Spreestudios – Platte and Kantine

Berlin

In the 1920s, this place was a magnet for the public - the Lichtenberg municipal bathing establishment was located here, with up to 17,000 visitors a day. At the beginning of the 1950s, the customs administration of the former German Democratic Republic (GDR) was set up here to monitor the Spree and remained in place until the 1990s.

In the following decades (1990 to today), the area was not used. Nature reclaimed the area - the former open-air swimming pool became an enchanted natural site - “nature took over”. Only two historic buildings survive from the time of the river baths: the former restaurant and the bath attendant's house. Two of the former three swimming pools have now been converted into a small marina with a waterline of around 200 meters.

In addition to the two listed buildings, two buildings from the GDR era have been preserved and are being converted and extended - the former GDR customs administration office building - “Platte” - and the associated former “Kantine”.

The site has remained completely unchanged to date. It is located at the widest point of the Spree (approx. 1.3 km) with an exceptional view of the “Insel der Jugend” and the Spreepark opposite and has a beautiful south-west orientation. The condition and atmosphere of the area provide ideal conditions as a film and photo location or for private and public events for up to 8,000 people.

With the “Spreestudios” site, the “Venturenauten” are realizing their first project directly on the Spree, in the Rummelsburg district of Berlin. Creative minds, organizers and free thinkers will find perfect conditions for setting up their studios, for variable and above all original spaces for exhibitions and events. The existing buildings will be respected and renovated. The density will not be maximized. A limited amount of additional construction is planned - in the form of additional storeys. The aim is to create a place of inspiration with sweeping views over the Spree and the city. A place that offers synergies to different users on the site in a very relaxed way. Between all the studio and workshop areas, the landscape remains very important as a connecting element. The open spaces of the former sunbathing lawn are to be generously preserved and will continue to define the character of the site in the future.

The existing floor plans were cleared and transformed into “open space offices”, the supporting structure was exposed, the surfaces were kept largely “rough” and glazed in color. Installations were bundled together and the Elo sub-distribution was laid visibly.

The additions to the existing buildings were constructed using the same system, utilizing the existing load reserves in steel (columns and beams) and reinforced concrete (ceilings).

Kantine

The single-storey former canteen building has three storeys with different storey heights, the outer wall is made of standardized aerated concrete elements in free laying with different widths, lengths and thicknesses. A particularly cost-effective construction that can be budgeted at just €280/m2 GFA (columns, beams, ceiling panels, façade elements).

The arrangement of the differently dimensioned elements gives this industrial façade a strong plasticity - similar to the original, plastically formed façade panels. The thickness of these aerated concrete elements meets the requirements of ENeV. It is monolithic and requires no additional thermal insulation. The surfaces are plastered in two layers and the surface texture and color are adapted to the existing StBn prefabricated elements.

Platte

The three-storey administration building will be extended by a double attic storey, the outer wall of which will also be constructed from standardized aerated concrete elements on a steel structure. The shape of the mansard is reminiscent of boats on a keel. The roofing of fired, flat tiles looks like the scales of a reptile. The roof surface can be walked on and extends the outdoor area of the Spree studios.

The New Leitz

Stuttgart

Leitz has long been a family business with an important history for the region and Germany. Intelligent innovations in the product range and production methods have guaranteed the company a secure position in the market for generations. Entrepreneurial wisdom and technical experimentation have also had a recognizable influence on the development of the buildings on the Leitz site in every phase of the company's development: demand-oriented construction, establishing the idea of the “multi-storey factory” as the maximum flexible building form for adapting to changing production requirements or working conditions, careful handling of the public outdoor spaces through contemporary façade solutions, etc. “Keeping things in proportion” was the motif - today we call it “sustainability”.

"THE NEW LEITZ" - International Green Startup Campus

In the future, “resources” will be thought of, developed and produced here in an overarching, networked way. By “resource” we mean cultural and social resources as well as individual or communal, technical and artistic, material, (production) processes, e.g. recycling. Lateral thinking is desired, networked thinking across borders is the goal: “International Green Startup Campus”, an accelerator that consciously seeks proximity to local companies and universities.

We want to create an inspiring place that brings people together to think about contemporary issues in a cross-cultural, multi-professional way. It is an educational project, a project for development, a project for production - a cluster in the best sense of the word.

To achieve this goal, we want to change the atmosphere in the area. People must be able to work and - temporarily - live here. We are removing buildings that are not protected and adding another building to the still rudimentary ensemble of buildings along Sieglestrasse, the future “Leitz Boulevard” (Area Management City of Stuttgart). This will create public and semi-public spaces for people who work or live here. It will be quiet, the surfaces will be unsealed and the uses will be mixed.

Mühlengrund district

Berlin

The “Mühlengrund” in Neu-Hohenschönhausen is a popular and still affordable residential area surrounded by large-scale urban structures on the northern outskirts of Berlin. In recent years, however, infrastructural deficits have become increasingly apparent here. There was no “neighborhood center” and there is a shortage of doctors. In order to meet the growing demand for housing in Berlin and the needs of residents who have lived here for a long time, the plots of a former department store and two unprofitable new buildings from the 1990s were released for demolition a few years ago. The convenient transport connections with a streetcar stop, a beautiful stock of trees and an existing neighborhood square with a remarkable fountain sculpture provided the backdrop for a neighborhood development with three buildings around this lively outdoor space.

Building

The open floor plans of the houses are filled with a variety of different types of apartments - apartments with outside access through a private garden, single apartments and multi-storey apartments with different numbers of rooms through to open-plan apartments for five or more people. The inner courtyards are private, reserved for the building community and their guests - with children's playgrounds, trees and benches for spending time together. The access systems are developed in a differentiated manner depending on the orientation of the building, use of the ground floor and optimized escape routes. The roof areas are extensively greened or covered with PV systems for tenant electricity. Stationary traffic is organized in the basement levels of buildings 1 and 3, as are a relevant proportion of the bicycle parking spaces, the building services and storage rooms for rental units.

Construction

The three buildings of different heights and storeys - VI - VIII - were developed as 3 free-standing volumes in timber-concrete hybrid construction:
The supporting structure of each building forms a simple skeleton of reinforced concrete columns with semi-precast flat slabs. This creates a “plan libre”, a free floor plan with options for different uses and layouts: Retail and other businesses on the ground floor, the health center and offices on the first floor as a “service horizon”, then the residential floors above with a diverse mix of apartments.

Facade

The building envelope is formed by curtain-type, storey-high wall elements in timber frame construction. The elements were completely pre-assembled at the factory, insulated and clad with rear-ventilated timber or metal façades.
The material of the outer skin changes from house to house or, in some cases, from building side to building side. This creates an exciting interplay of pre-greyed timber and white trapezoidal sheet metal facades. The steel balconies, which are also completely prefabricated, puncture the timber façades in a seemingly random rhythm. Together with the free interplay of the differently sized windows, this creates an exciting façade image.

Hafenküche

Berlin

The Hafenküche on the Spree is small - but not insignificant in terms of infrastructure: as a canteen for neighbors and surrounding businesses, for guest berths in the marina next door, for catering the saloon boats and as a beer garden for sundowners. The dilapidated structure was extended, with an unconventional look right on the water and a beautiful view over the Spree.

The structural remains date back to the early years of the GDR and before. They were structurally secured - not demolished - and renovated for energy efficiency. With just a few interventions, the identity of the site was transformed rather than eliminated. The industrial habitus was emphasized by interventions with light steel and timber constructions. The dock gates, which can be fully opened, allow guests to move freely between the beer garden, the harbor edge and the restaurant at any point.

The new components were installed with a maximum degree of prefabrication in a short time and with great precision and a high degree of efficiency. Timber as a supporting structure reduces the unavoidable thermal bridge to a manageable level and continues the architectural language of the location. The new roof cantilevers over the entire façade and thus forms a durable and constructive weather protection. The structures are bolted together and can be dismantled and reused with little effort if necessary. The center of the interior is an open kitchen around which all other functions are grouped.

Westfalenforum – Re-think the Urban

Dortmund

The era of inner-city shopping malls and shopping streets is coming to an end. New forms of retail and digital payment methods are making old-style shopping malls obsolete. This creates the opportunity to rediscover the city as a living space and give it back to the people. However, it is by no means possible to simply replace retail with housing.

Urbanity is created through plurality

This includes mixed uses as well as different residential typologies that promote real neighborhoods and generate identification potential for one's own “Kiez”. Sustainability, the lowest possible energy requirements, resource awareness from the limited building site to the selected building materials, mobility, etc. are self-evident aspects of the planning. However, the essential characteristic should be the creation of new places where people like to live.

A - Access

A group of buildings of different types with differentiated heights forms a new neighborhood. It is linked by public paths, alleyways and small squares - for access to the buildings, small-scale retail, eating and drinking or simply for spending time. The quarter is integrated into the overarching network of routes in the city center between the main train station, Westenhellweg and Marktplatz or Hansaplatz.

B - Mixed Use

The use of the buildings and floors will be mixed. Small, adaptable stores, cafés and restaurants will be created on the first floors, which can be extended to the first floor if required. Commercial uses will also dominate the first floor - offices, doctors and the like. The basement brings the buildings together under one floor and forms a continuous storey for parking spaces, technical rooms and other ancillary areas.

C - Sustainability

The use of materials, an efficient energy concept, short distances, the multi-layered linking of individual private and public mobility, social and cultural acceptance and other sustainability aspects are developed from the outset in a multi-professional team and brought together in an overall concept. A key starting point for us is the conceptual integration of an accessible green backdrop. As a structural break, it separates the floors with commercial use from those with residential use. It runs through the buildings, the courtyards, becomes denser at selected edges, recesses or terraces and gathers as a roof garden with bridges connecting all the buildings - a multi-storey park designed for the residents of these buildings.

D - Mobility

The group of buildings on Amiens Square is located in the immediate vicinity of Dortmund's main railway station with a variety of regional and national connections as well as direct access to inner-city public transport with buses and the S-Bahn. We will combine these options with a concept that ensures individual mobility - through an internal sharing system for e-bikes and cars that are available to residents. We expect to be able to at least halve the number of parking spaces required in this way. The remaining parking space requirement will be covered in the basement.

Competition Eisenwerkgelände Böhmer

Witten

The Böhmer ironworks is a former industrial site in Witten, where a company that prospered for many decades shaped urban development and has left its mark to this day. From the 50s and 60s of the 20th century until the closure of the company in 2020, structural development was always geared towards demand. The original industrial building stock is largely robust in substance, can be used flexibly due to its structure and has now been integrated into a mixed-use agglomeration as a result of unplanned development processes in the surrounding area. Today, large volumes of buildings with no specific use can be found in the vicinity of small-scale commercial enterprises, residential infrastructure and various residential buildings - a typical mix for the Ruhr region.

Activation

The building fabric is robust. Although it must be technically adapted to future requirements, there is no compelling reason for large-scale demolition. The existing buildings and the spaces in between not only shape the perception in the neighborhood, they also offer the best conditions for a comprehensive transformation process: the buildings are largely preserved. They are neutral in terms of use and are ready for short-term activation. For example, some of the halls of the former foundry are already being used as logistics space and may be activated in the long term for the “last mile”.

Each building is examined: for its structural quality, adaptability, “gray energy”, resources, future energy requirements, flexibility of use, fire protection, etc. In this way, targeted structural measures can be taken to secure the substance in the long term, to provide new uses in the short term and thus to generate the necessary income for the resilience of the portfolio.

Adaptive Idea

The initial aim is to maximize the adaptation of existing buildings - irrespective of any monument conservation assessment. Research evaluates the possibilities for transformations. The metalworking shop becomes a market hall, the assembly hall becomes a food court. Distinctive building typologies - “Blitz” - are preserved and integrated into the concept in a way that shapes the design and creates identity:

  • New building configures/contours the future context
  • Sample warehouse becomes student accommodation
  • Foundry becomes logistics location
  • Workshops may or may not remain workshops
  • Assembly hall 1 becomes a food court
  • Assembly hall 2 becomes a market hall
  • Office building becomes new office building or studio/student housing
  • Sample warehouse becomes student accommodation
  • Foundry becomes logistics location
  • Workshops may or may not remain workshops
  • Assembly hall 1 becomes a food court
  • Assembly hall 2 becomes a market hall
  • Office building becomes new office building or studio/student housing

Iterative process: Termination + Re-arrangement

Our proposal is less a concrete urban development concept and more an urban development strategy for gradual transformation and integration. A strategy that keeps options open that are perhaps not yet known today.

This is why conversion, demolition and new construction follow an iterative process. What stands in the way of development or is no longer needed is removed - if necessary, the material is recycled. Demolition and reorganization create new places, new identities - the visible/perceptible/contextual transformation process begins for everything that characterizes urban life: Eating + drinking, living, children, old people, doctors, care … „… come on you raver, you seer of visions, come on you painter, you piper, you prisoner, and shine …”.

“Housing” is becoming an important building block here. Existing buildings will be converted in various forms, e.g. the model warehouse on Westfalenstrasse, or new buildings will be constructed. To this end, we have developed a typology from the large-format, early assembly halls (not foundries) that offers differentiated spaces on a compact foodprint - flexible in use (residential, care, commercial) and adaptable and can offer variable-use spaces with greater room height on the first floor. In this way, the future urban scale is derived from the existing building, interpreted in a contemporary way and designed for the future. The load-bearing structure and technical concept (as much as necessary, as little as possible) also allow for future adaptability in these newly constructed building types. According to “Wittener Baulandmanagement”, 25% of the residential construction area will be built as subsidized housing. The floor plan organization of our buildings allows for this.

A central square will link the future and existing buildings and create a tangible, vibrant urbanity. From here, further development stages could open up the adjoining areas to the east - with residential buildings that take up the existing grain and formally follow a curved line. To the north, they face a public street (play street); to the south, private gardens are set up for the residential community. In this way, a “stitching” of new and old can gradually be created. A public thoroughfare - for pedestrians and cyclists - is to be created towards Erlenweg.

Mobility

In the future, there will be three types of traffic here - motorized, non-motorized and commuter traffic. We offer parking spaces at a central location in a garage.

Commuter traffic - logistics and commercial enterprises - will drive into the industrial estate via Westfalenstraße / vehicles for supply and disposal or ambulance transport will frequent the area temporarily and can use all roads - as can private deliveries.

Pedestrians and cyclists have barrier-free access to all areas

Private motorized traffic can drive directly to the buildings for deliveries and then park their cars in the garage.

Parking: The parking space concept is based on the mix of uses desired by the developer, including care, retail (market hall), medical practices, offices, residential, etc. Accordingly, no underground parking garage is required. Should the requirements/mix change, partial underground parking garages with natural ventilation can be built under the footprints of the buildings.

With its wedge-shaped cubature and variety of uses, the Haus am MIR mediates between the public use of the “Musiktheater im Revier - MIR” and the adjacent residential development to the east of Schalker Strasse. In terms of space and design, the new building frames and accentuates the current, very heterogeneous “non-space” on the east side of the MIR.

The recessed first floor is integrated into the public space through its transparency. This effect is reinforced by a homogeneously designed theater forecourt surface that incorporates the new building. An independent, highly recognizable urban space is created between the different uses.

Urban Densification Study Nordhafenquartier

Berlin

The most urgent goal of the urban densification study for the Nordhafen quarter is to develop the site as part of a future living environment in the new Europacity. For us, Europaplatz is an urban campus - a meeting place for residents and everyone who works here.

In addition, the study discusses the overlapping of private and publicly accessible uses, in parts also within the building, as well as the possibilities of resource-saving measures for heating and cooling at this special location.

A new district emerges

The inner-city wasteland, which has so far been largely unused or only rudimentarily used, is set to become a lively district with a direct connection to Berlin's main railway station. Despite good connections to the transport network, the site must nevertheless be understood and thought of as an island, as it is separated from the surrounding districts by various spatial barriers. Extensive railway tracks prevent direct contact with Wedding, while the Spree Canal forms a natural border with Mitte. New bridge connections will counteract this peculiarity, but will not be able to eliminate it. This makes the new district's own urban identity all the more important. The newly created town square as the heart of the new quarter will become an address, the inner open spaces a private garden.

Construction and sustainability

The complexity and multitude of technical systems should be kept to a necessary minimum. To this end, the solid components are activated and circulated with cool night air so that the coolness stored at night naturally compensates for the internal heat loads that arise during the day. Earth ducts and - where possible - evaporative cooling from the Spree canal provide the necessary cold air. Circulation through the building is initiated by a “chimney” (stair tower), which is routed beyond the parapet edge of the building.

Competition Urban Center

Berlin

The Urban Center Neu-Hohenschönhausen project is to be developed in accordance with the basic principles of ecological and social sustainability, a new hotspot of urban biodiversity, a green hub in the ecological system of the metropolis. Municipally controlled urban development based on public housing companies and cooperatives can prevent the negative effects of speculation and gentrification. The planning implements various standards of green in order to radically improve the social and ecological quality of the urban context. By combining nature-based solutions with the help of innovative and sustainable technologies, new qualitative, spatial and livable standards are created. The aim is to create a modern and lively new urban district. In the medium term, Falkenberger Chaussee will be rethought as a lively green axis in connection with the transport transition and electric motorization.

The available plot of land with a surface area of ​​around 6 hectares will be divided into three building plots: Building plot 1 along Falkenberger Chaussee: A large entrance pergola with a market hall marks the beginning and creates a connection with the neighboring shopping center. Living and working areas will be accommodated in a large modular and hybrid city shelf in two sections. With its perfect southwest orientation and green terraces, it fulfills people's desire for contact with nature and for sufficient open space with privacy. All infrastructure facilities of the new district, small shops, library, theater, family center, and an above-ground neighborhood garage for 200 cars will be integrated into the city shelf. A green high-rise building forms the signature.

Construction site 2 west of the cinema: The Berlin apartment block is being rethought, diagonally and modularly, with a diverse mix of apartments, duplex apartments if possible, townhouses integrated on the ground floor and first floor with direct access, enclosed and green inner courtyard, allotments in the courtyard and on the roof.

Construction site 3 east of the cinema: A cooperative quarter is planned here with a participatory planning model for alternative and communal forms of living and working, 30% cluster apartments + commercial/creative workshops + a public and green courtyard for community activities outdoors.

A completely CO2-neutral wooden city with model character is proposed. With wood from urban planning to the execution details, the new urban district also gets its own aesthetic identity. The creation of vertical and horizontal green spaces contributes to the character. Modularity and flexibility of the building elements in combination with simple and robust structures should promote longevity and a continuous mix of uses.

The interface between living and the city is formed by the ground floor and access zones, as well as arcades and staircases. The aim is to create lively spaces with a variety of uses and community offers. Courtyards and small, intimate squares offer village security, but also the opportunity for networking, new urban hotspots.

ECOLOGY

The use of state-of-the-art irrigation and rainwater collection systems and the selection of native plants - with high CO2 storage capacity, removal of air pollutants and attraction for pollinating insects - are among the core points of the project to increase comfort in the buildings and the well-being of the community. The new district is to have car-reduced living. The central district street will be traffic-calmed and developed as an Active Street.

In line with the ecological approach, Falkenberger Chaussee will be intensively greened and calmed with new rows of trees. A municipal sports park with covered sports fields will be built along the railway tracks in the green embankment under the railway overpass. On the south side of Falkenberger Chaussee, a new attractive train station with an integrated mobility hub (car sharing, e-bike station, bicycle parking garage) is planned in the form of a large roof folding over the tracks.

Competition Multi-Generational House With Day Care Facility

Salach

Salach is getting a new garden. A “garden for everyone”. It used to be allotment gardens, parceled out in miniature, inaccessible to the public. Today it is a large meadow, flanked by multi-storey residential buildings, the buildings of the local fire department, a house for senior citizens and the new “House for All”. The center is the garden. It connects everything and is intended to become a place where people enjoy spending time - a new green center, with fruit trees, other deciduous trees, beds that are cultivated together, deckchairs in the shade of the trees, small ponds in which rainwater collects and a photovoltaic pergola. The view goes over the railroad line to the Schachenmayer site - striking buildings, significant for the history of the town and important for its appearance in the future. We do not want to obstruct this view and propose a glass wall as protection against noise emissions from rail traffic - unpretentious in design, inconspicuous in the townscape.

Development + Floor Plan

The “House for All” is addressed on Messelbergstrasse. A small forecourt connects the entrances to all units and is also suitable for small events. The rooms of the Ü3 daycare center are located on the first floor and surround an approx. 800 m2 green inner courtyard with direct access to the “Garden for All”. The U3 nursery is located above this on the upper floor with a covered play terrace. This allows the children to keep an eye on each other. The family center is organized over two floors. The ground floor opens directly onto the garden and is connected to the upper floor via an air space and gallery, which also has direct terrace access to the garden. The entrance to the young people's rooms flanks the entrance square. The façade of the rehearsal room can be opened up completely, turning it into a stage and the covered entrance area into an auditorium. A terrace on the upper floor (east) extends the space and signals independence to the young people through the location and arrangement of these rooms.

The visitor parking lot will be at ground level, close to the entrance, between the “Haus für Alle” and the municipal depot. Delivery, waste disposal etc. are also arranged here. Only a small part of the building will have a basement - for storage areas, building services, etc.

Color

Areas of colour characterize the different areas. We don't want to simply “paint” walls and ceilings - all colors are independent elements. They are independent of the surfaces they are applied to and support the design and space. Some colors are reminiscent of summer, some of spring, others of autumn or winter.

Construction + Material

The house is planned as a timber frame construction. Ceiling and roof surfaces are integrated into the structure as compact timber hollow core ceilings and form a smooth soffit. The bracing is provided by combined access/sanitary cores made of solid timber components (cross-laminated timber), which are dimensioned for burn-off, as are other load-bearing components. All opaque façades are constructed with vertical inverted cladding. The façade surfaces of the upper floor overlap those of the first floor for optimized water drainage. All roof surfaces can do more - they are either energy-generating surfaces (PV) or greened, thus ensuring reduced rainwater runoff. The remaining rainwater is collected in a cistern and fed into the gray water system.

Energy concept

To optimize visual and thermal comfort while reducing investment and operating costs by minimizing the installed building technology and maximizing passive use (storage masses, air flow, etc.) - no dependence on fossil fuels.

Ventilation concept, particularly in the assembly areas, with mechanical basic ventilation - supply air via displacement air outlets, exhaust air at a central point for heat recovery. Minimization of the air volume to the amount of fresh air required by the user and consistent minimization of the pressure loss in the duct network and the ventilation units.

Low heating requirement due to high thermal insulation standards via surface heating (floor) with low temperature or ventilation (assembly rooms). Intelligent use of heat sources and sinks in the building, as well as covering residual energy requirements with natural resources wherever possible. Waste heat from artificial light can be used for temperature control in other areas (ancillary rooms, offices). This networking of energy sources and sinks makes it possible to “shift” the energy within the building and reduce the use of additional energy.

Activation of the soil using a compact soil absorber and a reversible heat pump for the supply and removal of heat as required, with a constant soil temperature all year round and a high heat pump performance factor to cover the base load when heating is required. Due to the large-scale thermally activated floor areas in the building, the existing soil temperature can also be used for direct cooling over a long period of the year. If the soil temperature exceeds the possibility of direct cooling, the compact soil absorber is used to cool the refrigeration machine (reversible heat pump).
