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.

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.

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.

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.

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).

The main site of the IdF derives its quality from its valuable tree population, but above all from its size. The existing building structure that dominates today does not reveal this size. We want to make this open space tangible as a landscape space for the people who will be trained here over several weeks. It should be a campus that allows easy orientation and where it is easy to get into conversation with others. It should allow privacy without being a barracks and at the same time be open to the public without ignoring security requirements. We are preserving all the trees and buildings whose appearance can enrich the character of the future site.

The urban figure follows the orientation of the site, the trees and the development. The gate is located at the S/E corner with a good view of the entrance, the shuttle stop, the pedestrian access, the underground parking garage entrance, the campus with its open spaces and the foyer/reception with hotel.

On the opposite side of the garden, the teaching rooms are lined up next to each other in three pavilions - with inner courtyards for differentiated lighting, a three-storey gallery facing the campus - transitory areas for vertical and horizontal access, informal areas for breaks and exchanges, partly integrated as loggias with storey-high segmental doors (glass panels) that open the gallery to the garden. The pavilion group ends with a single-storey, approx. 7.0 m high building, the restaurant. It is oriented both outwards, towards the gastronomic public, and inwards, towards the event space and the campus.

The entire pavilion group with gallery is aligned parallel to the building edges of lecture hall building C and is thus positioned a few degrees off-center to the other buildings. The interior garden thus opens up as an inviting gesture from Wolbecker Strasse towards the canal.

Material + Construction

All new buildings are built in timber construction - hotels made of room modules, all other buildings as skeleton construction with timber frame facades, glass facades or segmental doors (gallery, restaurant) for optimal open space connection and ventilation.

Open space concept

The basic urban design figure is interpreted flexibly and according to the situation: While a striking group of existing trees in the south forms the address, an urban joint of thinned-out trees in the north creates a visual axis to the canal. There is also a beer garden on this axis, which is also accessible to visitors and the neighborhood. The resulting diagonal promenade divides the campus into a meadow and a water area of the “Feuersee”. The latter is a retention basin as well as a connecting, calming and stimulating landscape element. The identity-forming trees on the large meadows will be preserved and their function as park space will be strengthened by a variety of new planting. A “piazza” will be created between the restaurant and the lecture hall building (C) as a central event location.

The client wanted an ecological, spacious house. It was to make maximum use of natural energy resources. It shouldn't be expensive, but it should also be differentiated, tailored specifically to a family of five, who required a lot of space and even more open space. In other words, very diverse requirements, which were met with a compact, elongated building.

Consistently oriented to the north and south and demonstratively constructed using an alternation of solid and skeleton construction, it is a low-tech solar house. Behind its radically minimized supporting structure of rods and tension cables, it opens generously to the south with its continuous, double-skin glass front, while a highly insulated, almost closed wooden façade extends along the cold north side, which only allows the opening of a narrow strip of light there.

All the adjoining rooms, solidly constructed and consistently arranged along the north side, act as heat buffers as well as storage masses, while the living compartments opposite them, which are transparent to the garden and the sun and kept flexible by sliding walls, derive their maximum benefit from the passive use of solar heat.

The space that links these two areas is equipped with skylights and space-saving cabinet elements that give it a clear rhythm and immediately help the person entering to find their way around, it is the prelude to an extended living space. In summer, it is a flowing living space, protected from excessive sunlight by the cantilevered shading of steel pipes arranged in a row. In the winter months, on the other hand, the heat buffer of the double-skin south-facing side allows the sun's rays to penetrate deep into the house unhindered, warming the indoor air and having a purely psychological effect.

The other parts of the extensive ecological concept are also efficient, from the choice of building materials used to feed rainwater into the cycle of a domestic hot water system. In the third and fourth expansion stages, this concept will be extended to include the active use of solar energy.

New Building On Aktienstraße

Mülheim an der Ruhr

The height and position of the new building is aligned with its urban surroundings. The front edge is flush with the neighboring building. In order to make the façades facing Aktienstraße more prominent and to increase the visibility of the building on the site, the volume is planned across the entire width of the plot.

A steel construction with a timber frame façade is planned, which will be curtain walling. This materiality is not only sustainable, but also creates a better quality for the employees working there thanks to its tactile feel.

Conceptually, the volume is organized in a strong base with a “flying” upper block to create a new scale on the very different fronts (e.g. fast train connections, industrial character with large and less street-going buildings). Instead of one large block, the concept focused on working the volume in its height and in two main parts, with less weight due to the “aerial plane”.

Usage

The allowance for a large market activity attracts a high contingent of users to the site. This is reinforced by the office workers and visitors to create a lively place.

The emphasis on the aerial floor of the parking speaks to the less human scale of the railroad line and the industrial buildings, allowing a new and elevated view of the surroundings. The two-story commercial space includes a storage area, mechanical rooms, restrooms and circulation cores. Intended as a large retailer, the design of the ground floor and first floor forms a self-contained and strong base, which connects to the office building via the equally self-contained and external access cores.

The upper four-storey volume will be an airy and transparent body for office use. The external circulation cores are important for the flexible use and organization of the floor plans.

Open spaces

The site is higher than street level. For this reason, the entrances to the project site are based on the gradient of the current access road. The ramp to the parking deck is planned as an independent element and sits on the straight level of the access road.

In addition to the ramp, entrance areas, technical and delivery areas as well as the required parking spaces for bicycles are planned. A smart pool is also planned for flexible mobility. Together with the public transport system, the parking deck meets the number of parking spaces required for office buildings and businesses.
