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.

Housing Construction In The Ruhr Area

Dortmund

The inner-city location is ideally suited for different groups of residents: young families, older people in small apartments or in shared apartments 50+, students in apartments or shared flats. A building that offers different types of apartments under one roof and thus provides the basis for a real house community. Access to the upper floors and the functional areas on the ground floor is via a central foyer with deliberately spacious circulation areas, which are available to the building community as a protected space for private events, children's play, etc. - as is the garden itself.

“High Density - High Privacy - Low Energy” is the theme of the architectural language. The building structure is compact, the circulation areas are equally yet communicative, the residential units have a differentiated typology and the largest possible private open spaces. All window areas are based on the same basic module, but their handling is adapted to the respective floor plans.

All necessary infrastructural facilities (waste management, storage rooms, building services, etc.) are housed in the building. This leaves the open space around the building tidy and reserved for garden use - with a direct link to the neighboring public green space.

The building has four upper storeys and a staggered storey with three penthouses to clearly articulate the urban contours. It has two independent entrances/exits. All floors are barrier-free and some of the apartments are handicapped accessible.

The first and second escape routes are routed via stairwells, which are located on the outer wall as nested staircases with minimal space requirements and are ventilated at the top.

The primary load-bearing structure consists of reinforced concrete ceilings laid on masonry walls. The ceilings are free of joists and are smooth and undisturbed from below. The masonry of the outer wall is monolithic (highly insulated) - with an additional mass shell for sound insulation towards Kaiserstraße and Karl-Lücking Straße. It remains open to diffusion throughout its entire construction. The surface forms an interplay of coarse and fine plaster textures. The floor plans are largely column-free. The space is created by non-load-bearing partition walls.

Restructuring Old Piano Factory

Berlin

Sustainable architecture means creating possibilities.

For our office location in Berlin, we have transformed an old piano factory in Berlin-Mitte into a residential and office building, giving it a new lease on life.

In doing so, our goal was to intensify the existing qualities while also meeting contemporary demands for living and working.
