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.

@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.

F40 – House of Business Friedrichstraße

Berlin

The property at Friedrichstrasse 40 is located in the southern Friedrichvorstadt district, a place that, like its surroundings, was culturally infused for years - inhabited by writers and artists. The plot was initially occupied by a two-storey residential building and later by a multi-storey, high-density front and rear building. The Skadamowski brothers, who are regarded as the inventors of 3D glasses and cinematography in Germany, lived here. In the past, the cultural character of the area, the adjoining entertainment district to the north - between Kochstrasse and Leipziger Strasse - and the Friedrichstrasse shopping street on the other side of Leipziger ensured a high number of visitors. Today, the former border checkpoint “Checkpoint Charlie” marks historical events. It is not far away and is clearly visible from Friedrichstrasse 40.

The new building closes the last gap in the streetscape.

Friedrichstrasse has a distinctly urban character here, with the courtyard area resembling a large garden. We will therefore extend the seven upper floors as deep as possible into the plot. As open floor plans, they will be variable in their use. The façade facing Friedrichstrasse will be formulated with technical precision, completely transparent with vertical glass slats to protect against heating and two-storey bays that link the building to its surroundings - an urban statement. The garden façade is different - also precise but with sliding doors, room-high, for large openings from which you can lean out. The sun protection is “woven” from textile material. In the interior, glass, wood and textiles come together - the city and the garden are interwoven here. Antje Schiffers' pictorial interpretation of the location accompanies the route through the public areas of the building. Sustainability in construction and technology as well as the media supply have already been pre-certified with the GOLD seal of approval by the DGNB.

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.

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.

House at MIR

Gelsenkirchen

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.

Residential and Commercial Building Königswall

Dortmund

The property on Königswall is located in the immediate vicinity of the Dortmunder U, the soccer museum, the Kampstrasse boulevard and the main railway station. It is currently developed with a 3-storey office building from the 1950s. In the immediate vicinity, adjacent to the west, a mixed residential and office complex with 3 buildings on a common base has just been built. A high-rise building forms a striking accent and the conclusion on the corner.

The ageing existing building has a clear, simple skeleton structure with a column grid of 4 meters. The original plans envisaged a building with up to 6 storeys. It can therefore be assumed that it is possible to add a storey to the existing building. The building has a full basement.

The current proposal for conversion and extension envisages 6 storeys, with an additional penthouse on the roof. The existing single-storey side wing in the courtyard is to be demolished. There are several options for the courtyard: from keeping it free as a parking lot to a completely single-storey superstructure as a ground-floor office extension of the front building with small green inner courtyards.

The planned conversion of the front building will have 1 or 2 office floors on the ground floor and 1st floor and apartments above, either 1-room apartments or 2-3 room apartments, some as two-storey maisonettes. A particularly spacious penthouse apartment, also extending over two floors, with a roof terrace and roof garden is planned for the top floor.

Access to the building will be completely reorganized with a new staircase and elevator on the street side. All units will be accessed from here. Up to 6 apartments are connected on each of the apartment floors. While the wet cores are largely predefined, all units can be designed as open spaces or with room divisions. The entire building is planned to be barrier-free. The building can be accessed from Königswall and therefore does not require a second escape staircase.

The new exterior design of the building is intended to attract attention with an expressive façade. This consists largely of curtain-type prefabricated elements. Their alternating suspension creates a dynamic and exciting façade appearance. At the front, the view is further enlivened by protruding bay windows. On the western front side, the façade structure is led around the corner and can have windows despite its location on the property boundary due to the existing neighborhood approval. The south side is to form an attractive and pleasant outdoor space with projecting and planted terraces, thus improving the quality of the courtyard. In conjunction with the planned new residential building on the opposite plot on Schmiedingstrasse, the character of the entire quarter will soon meet today's demands for a high-quality, inner-city living and working environment.

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.

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.

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.
