Extension Josef Albers Museum Quadrat Bottrop «Josef-Albers-Galerie»

A two-story wing has been added to the “Josef Albers Museum Quadrat”, situated in Bottrop’s historical park Stadtgarten. It accommodates temporary exhibitions and additional space for museum education, art storage and the workshop.

The new structure is situated to the northeast of the judge’s villa from 1913 and the museum buildings by Bernhard Küppers from the 1970s and ‘80s, which form the existing ensemble. The shape, materials and colours of the extension were chosen so that the different construction periods and their respective architectures remain legible but nonetheless form a new harmonic whole. The added volume has a rectangular footprint like the historical villa and is offset from the adjacent wing in such a way as to preserve the trees and the views to the north-east from the existing rooms. The pond, which was created after the last construction phase in the 1980s, has been moved a few metres closer to the access road, thus enhancing its presence.

Contrasting with Küppers’s steel and glass pavilions, the new extension appears as a compact structure with only a few deliberately placed openings, while its materials and colours refer to the older buildings. A cladding of powder-coated metal panels envelops the volume and forms a brim around the sawtooth rooflights. Along the outermost rooflight, the cladding tilts forward and generates a light funnel. In a similar fashion, the north-western facade partly unfolds to create a protected outdoor delivery area.

The ground floor on the Stadtgarten level contains the workshop, the art depot, an office and the library as well as the two educational rooms. The latter are accessed via the exhibition level and are oriented towards the pond.

Museum visitors enter the new tract via a connecting bridge from which a window affords a view of the park. The trapezoidal plan of the bridge makes it seem longer upon arrival and shorter on the way back.

The path through the eight exhibition rooms of varying dimensions is partly meandering and partly straight. Four large windows, one on each side of the building, enable visitors to enjoy vistas of the park, and passers-by to look into the museum. The works of art are largely illuminated from above by the sawtooth rooflights. The spatial proportions, the door and window openings, as well as the surface materials are selected to foster the perception of the art. Art takes priority: it has not simply been given more room in the extension; it has also been given “breathing space”.

Housing Development Zellweger-Areal

The Zellweger complex, set on a former industrial site, boasts outstanding landscape features. Two large ponds, originally created to generate energy from hydropower, a stretch of river, and a park-like area with mature trees define the site. The site is demarcated by the pond Zellweger-Weiher and the Aabach stream. Two residential buildings of differing heights are positioned here in alignment with the promenade of plane trees by the pond in the north and the tree-lined course of the stream in the southeast. The two buildings create an L-shaped green area between them, opening up to the west onto a group of trees and an existing high-rise office building.

Broad paths lead to the buildings through the open garden area, beneath which the garage is located. Pines are planted on the gently contoured lawn like green sculptures. The private front gardens at ground level are set off from the public green areas with spruce wood fences. These are framed by open, elegant concrete structures that also provide parking spaces for bicycles and contain mailboxes and shafts providing natural ventilation for the underground garage.

The northern eight-story building along Weiherallee contains 74 rental apartments, a bistro, two nurseries and a day care club. The building on the new Zellwegerweg, set along the Aabach, ranges from three to five stories in height and houses 61 rental apartments along with a multi-purpose common room. Most of the apartments in both buildings have living/dining/kitchen areas that extend through the building, opening onto both the green inner courtyard and the pond or stream. The principle of the living/dining room extending from front to back was articulated differently in the two buildings. In the building on Zellwegerweg the space narrows in the middle to form an entrance area and then widens again to either side to form distinct zones for the living room and eat-in kitchen at opposite ends of the apartment. The rooms are arranged around the periphery of this central space. In the building on Weiherallee the entrance area provides access to the rooms and leads to the living/dining room that runs across the apartment. The subtle angling of the balconies offers outdoor areas of varying depths and provides a formal echo to the large-scale angled sections of the two buildings, adding a lively and sculptural touch to the volumes of these two housing ensembles.

The façades are articulated by layers of rhythmically offset thermally modified spruce wood planks and openwork prefabricated concrete parapets, which protrude somewhat beyond the wooden cladding to protect it from the weather. On the balconies, the concrete band projects further forward to form the parapet.

Office High-rise Andreasturm

The office high-rise Andreasturm is situated on a triangular plot of land that has become available between the spread of railway tracks at Oerlikon station. The pentagonal tower, the property of the Swiss Federal Railways, is 80 m high, with 22 above-ground and four below-ground storeys.

Precisely placed cantilevers on the 12th floor divide the building into a middle and a head section, making it look slender or flat from a distance, depending on one’s vantage point.

An expansive base anchors the structure in its surroundings and opens it up on three levels. The main entrance with public facilities and a small, new plaza face the traffic-calmed Andreasstrasse. The premises of anchor tenant Amstein + Walthert are accessed directly from the higher railroad platform while the delivery entrance is on the lower street to the rear.

A well-appointed, double-height lobby welcomes tenants and visitors, who reach the upper stories via the lift lobby. An open staircase leads up to the first floor and the main tenant‘s reception desk. The tenant’s public spaces are arranged around a central core: a “piano nobile” with conference rooms, a gallery and a staff restaurant in the protruding portion of the base.

The skeleton of the high-rise is reinforced concrete with a double-shell element façade. Flat slabs span up to 9.30 meters between the core and the prefabricated concrete supports along the façade. The column-free spaces allow for flexible layouts and workplaces with natural daylight. The double-shell façade consists of an inner layer with slender windows that can be individually opened, and exterior glazing with horizontal parapet bands, into which copper and gold coloured inlays have been laminated, their tone varying to match the angled surfaces of the façade. The appearance of the building changes depending on the weather and lighting: at times, the tower may look like a flat, reflecting surface; at others, one can see the filigree vertical structure of the interior.

Housing Development, Färberei-Areal

Four new buildings were planned for the site of the former “Färberei”, or textiledyeing factory, to be constructed in successive stages in order to establish an ensemble together with the refurbished “Blue Factory”. This former industrial area is thus gradually developing into an urban residential, commercial, and office district. The elongated, cubic buildings are set into the hillside like a fan, creating flowing interim spaces that expand to form plazas. The colors of the buildings were developed during the various construction phases in collaboration with the artist Harald F. Müller.

House 1

In the long, five-story House 1, constructed parallel to the steep slope that descends down to the lake, 35 apartments are arranged in a variable mix of 3.5 to 7.5 rooms. The two floors adjacent to the Blue Factory hold flexibly dividable office spaces, while a day-care center is provided on the ground floor.

A characteristic of the single-story apartments is the arrangement of the rooms around a central living and dining area, with a connection to the kitchen. Each apartment possesses two loggias that are integrated into the building volume and extend the continuous living space toward the lake and to the south. Floor-toceiling windows enhance the sense of spaciousness. These let southern light into the rooms and provide vistas over Lake Zurich to the north and the lakeshore opposite. The outdoor spaces in the penthouses are designed as large patios that not only open to the façade, but also to the sky. Due to the hillside location, the typology changes to duplex apartments on the two lower floors. Here, the daytime area with living and dining rooms and kitchen extends over the entire depth of the upper floor, while the nighttime area with bedrooms facing the lake is situated on the ground floor.

The grid pattern of the monolithic load-bearing exposed concrete structure defines the exterior. The concrete surfaces of the façade are washed in white, while a metallic note is introduced for the components in the façade openings: in the wood-aluminum window frames, in the blinds, and in the glass parapets’ subtly reflective surfaces. Glossy silver paint was used for the elevator cores, while the concrete walls of the staircases are painted a matt yellow-green in some areas, and treated with a transparent glaze in others.

House 2 and 3

In the concluding phase of development, two further buildings, with a small park set in front, will complete the ensemble in the northwestern part of the site. In house 2 the emphasis is on smaller, low-cost rental apartments for families, while house 3 focuses on providing housing suitable for older people.

In order to make the most of the sunny southwestern side of the building, which is however exposed to noise, single-story apartments were created for house 2 with a living, cooking, and dining area that runs through the entire depth of the building but which is set at an angle. This floor plan produces a varied assortment of 48 apartments ranging in size from 2.5 to 4.5 rooms. The bathrooms, ancillary areas, and circulation cores are arranged in the central part of each apartment, dividing the living area into two spaces of equal size and hence offering flexible use. In the eastern part of the building the upward slope of the site makes it possible to offer duplex apartments on the ground floor. At the western tip of the building, facing the square, rooms for public use are incorporated into the design.

The compact footprint of house 3 allows for five 2.5- to 5.5-room apartments on each floor. Two apartments are open to the exterior on one side, facing southwest, and two wrap around the corner of the building on the southeast side. The fifth apartment, oriented toward three sides, is located on the northwest side of the building. This floor-plan configuration, incorporating apartments of differing sizes on each floor, coupled with a care facility at ground level, responds primarily to the needs of older residents.

The exterior of both residential blocks uses light beige and pebble-gray glazes. These subdued tones are complemented by brighter colors in the interior stairwells, which are lit from above via skylights.

House 5

A site in the southwestern portion of the plot, near the railway tracks and sloping down on two sides, was chosen for a six-story building with eleven condominiums. A range of variously configured single-level units was developed for this building, complemented by specially designed penthouse and duplex apartments. On the upper floors the apartments open to the exterior on three, or even four, sides, affording vistas both over the lake and to the mountain panorama in the south. Due to the steep slope of the site, the apartments on the lower stories are open only on the side facing the lake to the northeast. The design nonetheless incorporates generously proportioned outside areas for all apartments: the two upper apartments enjoy large roof terraces thanks to the slanted form of the building volume, while elsewhere in the building the apartments include either one or two loggias depending on size. In addition, the two ground-level apartments have external seating areas.

Accentuating the play of light in the stairwell, the inner-facing longitudinal wall is painted gold from the top to the bottom of the building, complemented in the entrance area by a pink-painted portion on the facing wall. The load-bearing monolithic exposed concrete façade structure is finished in a brown glaze, while all cutouts in the building volume and all façade openings, loggias, and roof terraces are left unpainted. A subtle golden anodized finish is utilized on the exterior for the wood and aluminum window frames.

Würth Haus Rorschach

A greenish crystalline building responds to the unusual location of the site, set between the edge of Lake Constance and Churerstrasse. Walkers and passers-by experience a glass structure that oscillates between transparency and shiny reflective surfaces that multiply the natural beauty of the setting. The architecture affords views out to the surroundings, glimpses into the building, and sightlines through it to the park and lake.

The interior offers staff and visitors generously proportioned sequences of rooms - workspaces, communication areas, and leisure zones - as well as providing space for product presentations and art exhibitions. The structure responds to the train station building with lower volumes and reacts to the expanses of the park and lake with a higher segment. There are plans to add an extension on the eastern side in a future phase of construction. Toward the street, the volumes give shape to a range of external spaces through precisely defined projections and setbacks: in the middle is the entrance area, to the east the vehicle access and workshop zone, and to the west Bahnhofsplatz, the station square, which is expanded toward the lake. Maple trees set in a perpendicular configuration characterize this space, and also continue as rows along Churerstrasse.

Approaching from the station, a broad canopy signals the main entrance. The various user groups - visitors, people attending courses, and company staff - enter the building through a large lobby and are guided from this point to the different parts of the building. On the ground floor and first floor, the public functions - training and conference rooms, as well as the restaurant - are grouped around a foyer with an open courtyard in the center and are linked by a sweeping stairway. Both the conference area and the separate exhibition spaces can be accessed directly from the exterior, allowing the option of using these areas independently from the rest of the building. The exhibition area guides visitors from the entrance to two different-sized exhibition rooms, which are located on the first floor of the southern part of the building and are naturally lit from above. The structure of the shed skylight over the exhibition spaces simultaneously supports the enormous projecting canopy over the entrance. Office space extends over four stories in the highest part of the building, which is not open to the general public. Informal meeting areas with balconies facing the lake, transparent or closed-off meeting rooms, and individual offices alternate here with open-plan office areas.

A double glass envelope encases the building. The inner layer is made up of triple glazing and metal-clad thermal insulation. The external, back-ventilated layer is composed of offset greenish glass panes equipped with a fine mesh insert with a metallic luster. This creates a rhythmically articulated glass curtain that provides protection against wind from the lake and noise from the street and also against excessive heat and cold. The predominance of glass in the building materials is continued on the roof in the form of CIS photovoltaic panels.

Housing Development Goldschlägi

The Goldschlägi site is located adjacent to the railway station in the center of Schlieren. The site borders a wide stretch of railway track to the north and a green space to the south that serves as a vista and access area for the apartments. The elongated, narrow residential buildings emphasize the orientation of the plot parallel to the tracks, but rigidity is alleviated by their offset alignment. The height of the complex varies between three and six floors, resulting in a division of the overall volume that creates differentiated outdoor spaces.

The urban concept is reflected in the individual apartment types. Those rooms in which noise level is of less relevance, such as the access cores, kitchens, and bathrooms, are located on the north, facing the tracks. All living rooms and bedrooms, as well as the generously proportioned, projecting balconies, face south over the garden area. Their staggered positioning provides residents with an outdoor space one or two stories high. The parapets and the side elements are composed of colored glass panels that ensure privacy and cast bright blue shadows when the sun shines.

The complex is divided into 105 apartments with different floor plans and of varying sizes ( with 1, 2, or 3 bedrooms ). All have one open-plan living / dining / kitchen area that is naturally lit from both sides. The kitchen and bathroom form one module in each unit, and a large number of different floor plans have been generated through its alternate siting.

The projecting and recessed façades facing the tracks have been finished in a bright red. The black-framed windows of various sizes and division – belonging to the kitchens, bathrooms, dining areas, and staircases – create a rhythmic pattern. The south-facing façades and the end walls are of white plaster, with the window frames and sunblinds executed here in anodized aluminum.

Concrete floor slabs cast in-situ and prefabricated concrete supports give the complex a regular structure. Bracing is achieved by means of the stairwells and the external end walls. The concrete structure is encased in large, prefabricated and insulated timber elements, clad with a rear-ventilated and plastered façade. Using frame construction throughout and avoiding load-bearing internal walls wherever possible has ensured a high degree of flexibility with regard to the floor plans.

Location Schlieren, Switzerland

Programme Two buildings with varying heights (3 to 6 storeys); 105 rented apartments, different typologies and sizes (2.5-, 3.5- and 4.5-room apartments), less noise sensitive rooms orientated towards the tracks; living accomodation / bedrooms and balconies face the green space to the south; underground parking

Swiss Museum of Transport – Road Transport Hall

The concept for the new Road Transport Hall differs from the first design during the 1999 competition. Originally conceived as a three-story building with concrete shear walls, a load-bearing, glazed façade construction, and bridge-like ramps on the exterior, the new building is to have two stories, be more economical, and in particular offer greater flexibility. It is an exhibition building that in its rudimentary simplicity and as “dark-gray black box” is reminiscent of those buildings countrywide that are designed for the storage and housing of cars, i.e. multi-level parking garages and automobile repair shops. An automated parking system is employed here; a shelf-like structure operated by a mechanical lift displays the collection of cars densely positioned one above the other and out of reach. At the touch of a button, visitors can move one of the cars forward to look at it close up. The open areas on the first two levels provide space for running temporary theme-based exhibitions. A workshop shows the visitors how the vehicles are maintained and repaired.

The façade cladding of the mainly closed building volume is composed of sheet metal in differing formats and colors. Instead of standard façade sheeting, however, or metal from car bodies (as envisaged during the preliminary project), sheet-metal traffic signs have been recycled here: highway signs, guidance and information signs, warning signs, marker signs, and place-name signs. The signboard walls, which spatially delimit the Road Transport Hall, indirectly refer to the great freedom of mobility afforded by private transport, which is directed and regulated with the help of such boards. Furthermore, they also refer to numerous locations near and far that might be the home towns and cities of the visitors, who arrive via diverse traffic routes and using different modes of transport in order to discover more about the subject here. On the rear façade, toward  the neighboring buildings, the signs are reverse-mounted, which means that the printed side faces the building while the untreated, metal side faces outward. Thus, the neighbors see these boards just as road users would see the signs meant for the oncoming traffic – from the back.

«Platform» Office Building

In the immediate vicinity of Hardbrücke railway station, the seven-story office building called Platform completes the ensemble comprising the high-rise Prime Tower and its annexes Cubus and Diagonal. The building’s volume, with various angles, reacts to the urban situation, providing a coherent link between the station and the new central square. A two-story-high passage through the building connects the square with the public pedestrian and bicycle path along the side of the tracks as well as with the new pedestrian underpass to Hardbrücke Station. In addition, the passage acts as a generous covered area outside the entrance foyer.

With its pronounced horizontal and layered design, the building contrasts with the Prime Tower nearby, effectively forming its reclining counterpart. As in the tower, the stories increase their floor area as the building rises, made possible by various projections. the volume of the building is also subdivided by courtyards that cut into the west and south sides and ensure well-lit office spaces within, as well as by the angular projections in the façade.

The central, prestigious entrance foyer forms an additional internal open area. A tall atrium flooded with natural light links the entrance level with the office floors above. Its function as a hub that lends the building its identity is additionally underlined by the open staircases and adjoining seating areas on the office floors. Dark glass balustrades mirror the space and the light in multifaceted reflections, creating a kaleidoscope effect.

Next to the entrance foyer on the ground floor are a restaurant, a cafeteria, and an auditorium. A wide, inviting staircase leads from the entrance level to the customer lobby on the first floor, from which the various conference rooms can be accessed. the levels above provide office space for around 1,000 staff. Although the building has been conceived as a corporate headquarters, the positioning of core facility areas permits a variety of office typologies if required in the future, including the division of each floor into a maximum of four separate rental units. Wall and ceiling paintings by Nic Hess, wallpaper and drapes by Lachmayer/Nobis and a textile sculpture by Ernesto Neto complete the interior.

To be able to meet changing spatial needs or different uses without radical structural alterations, the building has been designed as a load-bearing skeleton structure with reinforced cores.

The glazed façade is articulated by horizontally layered bands of parapets and windows. The double windows hold sunblinds in between and help reduce noise from outside. The inner windows can be opened for ventilation purposes toward the interim space of the double-skin façade. The slightly reflective outer glazing shell and parapets accentuate the building’s folded structure.
