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.

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.

Hafenhaus

Berlin

The Hafen und Hof GmbH & Co. KG has a large number of different users. In addition to various bus operators, there is also a marina with boat rental operators and a restaurant on the site. In order to expand the offer on the site and meet demand, a new building block is being planned in this ensemble.

In the future, the new “Hafenhaus” building will provide additional gastronomic offerings, space for boarding house use, office space and space for port operations. The aim is to upgrade the location as a whole and meet the needs of current users for more space. Large parts of the first floor are planned as an air floor. This is to ensure that bus operations can continue on the site without restriction.

On the upper floors, 19 units are planned as a boarding house in various sizes. The boarding house is an accommodation facility designed for guests with longer stays. The units facing the waterfront are a special feature. A new gastronomic concept is planned for the first and second floors. The space, which is open across both floors, is to be operated as an exclusive restaurant in a living room-like atmosphere in future.

The top floor is planned as a restaurant and event space. Especially at weekends, when the bus service on the site is largely at a standstill, many Berliners already make use of the gastronomic offerings on the site. The roof terrace is intended to expand this offer both in terms of space and content. In addition to the restaurant, a pool is also planned on the roof.

The building will be constructed as a reinforced concrete skeleton structure. Only the core on the north-western side of the building will be solid. Lightweight partition walls will be made of drywall.

A comprehensive redesign of the water's edge is planned to positively influence the atmosphere on the property. The site has already been developed and the new building will be connected to the existing infrastructure.

Heat will be provided by a combined heat and power plant. In future, this will not only supply the new building, but also the existing “Hafenküche” restaurant.

@55 House Of Business

Dortmund

The new “@55” building is located within the “Stadtkrone Ost” conversion area in Dortmund.

The new building stands on a 20 m high embankment and borders directly on a nature conservation area. The storeys are offset from each other, creating a terraced landscape to the south, which can be converted into additional office space if required. On the north side, the storeys overlap the entrance by up to 12 m, creating a cascading roof.

The loads of the cantilevered storeys are bundled at the top and guided downwards with tension cables that follow the slope of the outer wall. Here, the resulting forces are transferred to the ground via a counterweight (approx. 150 m3 cavity filled with sand).

The storeys are unsupported and undetermined, i.e. uses are not predetermined. The building currently houses a restaurant, a medical practice, offices and an apartment.

The façade is homogeneously covered with horizontally laid profiled glass/structural glass, which is held in a point-like manner. This creates a crystalline structure that gives the building an abstract identity. In some places there are ribbon windows behind the outer skin - here the profiled glass can be rotated around the horizontal axis using a simple mechanism - thus providing an unobstructed view of the surroundings.

Competition Wellinghofer Straße

Dortmund

The competition site on Wellinghofer Strasse offers excellent potential for a housing project with apartments, especially for families with children - embedded in a green corridor with a wide view of Phoenix West, a school and a potentially good position for gardens with a south/west orientation. Unfortunately, the provisions of the legally binding development plan are far removed from the requirements of the current Climate Protection Act. For example, a large number of existing trees are to be disposed of, a high demand for car parking spaces is defined, which cannot be met in a basement garage alone and therefore requires additional sealed areas above ground. The idea of a “sponge city” is thus thwarted. The planned north/south orientation of a large part of the future development does not allow for well-lit apartments with maximum use of the buildable area - building depth 18m.

We have therefore decided to deviate from some of the stipulations in order to create a balanced relationship between private and semi-public spaces and to create favorable conditions for climate-friendly and resource-conscious construction.

Living with nature

Children play in the fresh air, splash around in the natural pond, neighbors with green fingers garden in the vegetable patch and the fire pit is the place for spontaneous or planned celebrations. The existing green corridor is to be visually transferred to the private gardens and semi-public open spaces of the building community. In this way, we want to ensure ecological diversity and the infiltration capacity of the soil as far as possible. The underground car park will be enclosed with small walls, steps and seating, staggered paths, planting beds and water basins or infiltration troughs. The artificial geometry of the garden is a basic pattern that runs through the entire quarter and deliberately contrasts with the natural wildflower meadow, flowering fruit trees and native shrubs and hedges. Drought-resistant plants and moisture-retaining ground covers are preferred when selecting plants.

Access + Apartements

All building entrances and the entrance/exit to the underground parking garage are addressed to Planstrasse. The entrances are barrier-free and wheelchair-accessible. Arcades are designed so that they can be meeting points for informal exchanges. Each apartment is oriented on two or three sides and is therefore very well lit and ventilated. In construction site 2, we are currently planning large first floor apartments that are accessed via an inner courtyard and private front gardens. The specific staggering of the volumes allows for a roof terrace on each building for use by the building community.

Concept Floorplan

The floor plan concept contains only a few fixed components (shafts, columns or walls). The type of construction allows for a high degree of floor plan variability within the supporting structure and thus enables different layouts - apartments from 25 m2 to 250 m2 - from one-room apartments to cluster apartments for shared flats or integrated “townhouses” with individual entrances and private gardens for families. This means that a large number of small and medium-sized apartments can be created, as well as a smaller number of larger apartments. In this layout, we are proposing approx. 83 units on a gross floor area of approx. 9,200 m2, mainly apartments for families with children in various apartment typologies.

Building Equipment

The energy requirement is covered without complex building technology, via district heating. To this end, the new residential quarter in Planstrasse will be connected to the city of Dortmund's new low-CO2 local heating network. The building envelope (Efficiency House 40) of the houses in conjunction with low-temperature underfloor heating and façade-integrated decentralized ventilation units with highly effective heat recovery reduce the primary energy requirement. Shafts are bundled as far as possible and their number is reduced to a minimum, with external awnings (south-facing windows) or curtains on the balconies, depending on the orientation. Generous window areas with triple glazing allow - if necessary - a high natural heat input into the apartments in winter. PV systems (CIS solar modules) will be installed on the roofs to generate electricity (60% of the gross roof area). The yield and consumption data will be available to all residents on a touch panel in their apartments. The aim is to motivate them to use energy sparingly.

Construction + Architecture

Hybrids are created from timber (exterior walls, interior walls, columns) and prestressed reinforced concrete hollow core slabs (ceilings) with a high degree of prefabrication and great detail quality as a “detachable” construction - designed in such a way that they can be separated by type and treated separately - for reuse or disposal. StBn is used where sound and fire protection requirements make other constructions uneconomical - in the garage as a monolithic StBn construction, in the rising storeys with prestressed concrete hollow planks, which are characterized by a minimized use of materials: -50% concrete and -70% steel. Wooden walls and columns (west side) form the primary supporting structure with a grid of 7.5 m on which the prestressed concrete hollow core slabs are placed. Cores for TH and elevators form part of the bracing. Closed wall panels also have a stiffening effect on the structure. The exterior walls are brought to the construction site as a timber frame construction with a pre-greyed timber cladding and assembled to the supporting structure there. The principle of “no waste” should be adhered to during production and erection on site.

Urban Densification Strategy Max-Eyth-Straße

Dortmund

The market development in Dortmund as an office location is stagnating and the commercial offers are essentially identical. We propose a strategy that restructures the large-scale property at Max-Eyth-Strasse 2 in a small-scale manner and thus activates it in an invigorating way.

Preserving qualities, creating diversity

The existing trees will nevertheless be largely retained and combined with a simple but sophisticated group of buildings of different typologies.

The design is based on the same scale and connected via a central access route, creating a family of buildings with a recognizable formal connection, while at the same time giving the individual buildings a high degree of independence with their own addresses.

Urban Densification Strategy

On Max-Eyth-Strasse, the buildings are set back 5 m from the edge of the sidewalk. Towards the property boundary in the east, we will preserve the existing trees, in particular the dense green backdrop, in order to protect the adjacent private gardens. This will create four decentralized addresses. All four are located on a central access route. In this way, densification takes place in the center of the group of buildings - at the edges, especially towards the neighboring residential area, the contours dissolve.

The size, storeys and arrangement of the buildings at the four addresses are designed as a variable system that can react to the actual space requirements.

The positioning of the future buildings ensures the necessary noise protection both inside the new ensemble and from the neighboring residential buildings.

Building typology And Floorplan Efficiency

The building typology is based on an efficient construction grid of 1.35 m. The floor plan dimensions allow adaptation for different conditions and uses.

The fit-out can be carried out in different materials according to the tenants' wishes: Plasterboard, wood, glass or composite. If required, individual buildings can be linked together on different levels.

The resulting office spaces are ventilated naturally as far as possible. Mechanical ventilation and air conditioning are available on request as optional extras; the space provision for this is taken into account. The ground floor zones of some buildings (variants 1 to 3) can be rented out as retail space.

Porsche Center

Dortmund

Porsche is synonymous with technical perfection, formal precision, passion, speed and understatement.

With its new building, Porsche Dortmund gives significant shape to the sensuality of these attributes.

The building is constructed parallel to the highway (B1) - as a direct entrance to the Airport Business Park. The building consists of two components - a base to absorb the topography and a metal membrane resting on it, which envelops a space 8 meters high and 130 meters long. The silhouette is reminiscent of an extruded aluminum profile - a significant reference to the high technical qualities of PORSCHE products. Everything is visible - technical service is staged.

A café lounge provides online images of current racing events, shows ongoing production processes or test runs of the PORSCHE typology. At night, the building makes a media appearance and communicates PORSCHE images via the transparent façades with light installations. The building's structures are all prefabricated - the concrete construction of the base floor consists of inclined columns curved in three directions, computer-animated laser and welding machines produce precise steel and aluminum components that are assembled as individual modules on the construction site to form the building.

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.

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.

Multifunctional Space Extension

Berlin

The existing building to be extended is a service hall for bus operations with offices. A multifunctional room for team meetings, workshops and office use will be added to these usage units in an extension to the existing roof. An additional kitchenette is used for catering.

The existing construction of the ceiling above OG2 was designed and constructed as a “roof”. The load-bearing capacity of the structure is not sufficient for future use with traffic loads. For this reason, the structure was reinforced. Steel girders and prestressed StBn ceiling elements in accordance with the structural analysis form the new ceiling level. The roof structure of the additional storey is constructed as a mixed structure of timber (laminated veneer lumber) in the longitudinal direction and steel (HEB) in the transverse direction in accordance with the structural analysis. Verification erected. Supports are positioned as X/V elements on the existing load-bearing axes.

The façades are designed as elements - the N/E façade as a closed timber/metal façade, all other façades as sliding glass doors.
