The generously laid-out housing estate has been built in Bursa, which is Turkey´s fourth largest city. There are 28 blocks of flats on the estate with a total of 385 modern flats, in different sizes to suit all of the residents´ requirements.
The entire estate is integrated skilfully into the surroundings by means of the simple but expressive shape of the residential buildings. In addition, social facilities like an indoor swimming pool, a fitness centre and a cafe have been built for the residents.
The housing estate is suitable for families and it offers an extraordinarily large number of green spaces, which are laid out in the form of different thematic gardens.

Project galleryMulti functional hall Bietigheim-Bissingen
To create new playing areas on the DLW company´s premises for the ‘Steelers’ Ice Hockey Club and the ‘SG BBM’ Handball Club the town of Bietigheim-Bissingen comissioned a feasibility study. The entire complex comprises a multi-functional hall (5,000 spectators, based on the ice sports rink), an ice sports training hall, a handball training hall, a fitness centre and a multi-storey car park.
The successor to the individual independent parts of the utilities and buildings will be integrated into a building complex - but designed independently in extent and height - above a curved plinth at the development´s level and ‘laid out’ next to the railway embankment. The new multi-functional hall forms the well-defined and dominant centre of the entire complex, which meets the passengers arriving at the railway station as well as those emerging from the underpass on the B27 highway. A generous ramp guides the visitors parallel to the multi-functional hall onto the plinth level.

A hotel with 100 rooms, a conference area and health spa is being planned for the town of Solingen in the German state of North Rhine-Westphalia, which is famous for its metalworking and exhibition centre.The business hotel in the 4 star category is situated directly next to Solingen´s main railway station. The hotel is tailored to suit businesspeople from Cologne and Düsseldorf, because it is situated half way between  the two on the Inter-City Express railway line.
The main body of the building is graduated in height in order to fit in with the small town´s surroundings and its length is subdivided into three components, which are staggered against each other laterally.
The windows are the characteristic element of the courtyard´s façade, which are south-facing and unfold from the façade. The ground floor is turned away from the line of the building and this gesture draws visitors into the lobby. The restaurant on the ground floor opens onto a garden terrace in the planted inner courtyard.

Project galleryMercedes-Benz Arena Stuttgart
Mercedes-Benz Arena, home ground of German major league football club VfB Stuttgart, will be transformed into a football-only facility during the next months. Construction work kicks off with the lowering of the playing field and demolition of the “Untertürkheimer Kurve” grandstand. The main and opposite grandstands will be extended towards the playing field bringing the spectators closer to the action. All work will be carried out while regular match day operations continue.
The next step includes rebuilding the “Untertürkheimer Kurve” grandstand as a two-tier structure at minimum distance to the playing field. With additional business and VIP areas this section of the stadium is an integral part of the overall transformation into a state-of-the-art football arena. Integrated into the “Untertürkheimer Kurve” structure is a 2,000 spectator sports-hall. The sports-hall has a separate access and can be operated independently of the stadium.
As soon as “Untertürkheimer Kurve” grandstand opens for spectators work will commence at legendary “Cannstatter Kurve” grandstand on the other side. Almost directly behind the goal-line a two-tier structure with a large standing terrace for VfB supporters will rise. Even a supporter's sports bar is included.
Throughout the construction phase a 40,000 spectator capacity will be maintained. Eventually the stadium will hold 60,000 spectators during league-matches when work is finished.
The membrane roof of Mercedes-Benz Arena will be extended accordingly in order to further on keep almost all spectators out of the rain.

The first real football stadium for 17,500 Bulgarian spectators is planned to be built on the previous training and sports site of the ‘Lokomotive Mezdra’ sports club. 
The stadium´s unique site is bounded by a wooded slope in the north and by the River Iskar in the south; it also closes off the river valley. 
The roof´s shape opens towards the west in a welcoming gesture and it attracts the spectators into the stadium. The stadium´s interior can be experienced far away already from the pedestrian´s perspective and the atmosphere in the arena is noticeable. 
The roof´s overall shape wraps itself around the stadium: it lowers itself in the area of the rear gate´s stand in the east and adapts itself to the tribune´s lower height. The reference to the dramatic landscape is emphasized as a result.
The stand´s individual components are anchored onto the site as sweeping, heavy ‘concrete sculptures‘, over which the aerodynamically shaped, light-weight roof floats.

Galatasaray Sports Club’s new Istanbul football stadium is located on the European side of the Turkish metropolis.
The stadium will belong to the prestigious UEFA Five Star/Elite Stadium category. It holds 52,230 spectators; VIP facilities include 150 sky-boxes. The stadium features a retractable roof – the first of its kind in Turkey – and a 3,000 vehicle underground garage.
The topography of the sloped site with a level difference of up to 60 meters from one end to the other posed a particular challenge. Special foundation measures were necessary – especially for the large “super-columns” that support the roof structure.
Construction work is well underway. Opening is scheduled for the end of 2010.

The location at the western and eastern end walls allows an undisturbed building structure with a clear grid using the very economical steel-composite construction system, which on the other hand makes a relative short construction time possible.
The always difficult integration of a car park into a naturally dominated environment shall be optimized through the consciously used simplicity
in the design of the facades (example multi-storey car park of the Gottlieb Daimler Stadium) or rather through facade greenery.

Modernization includes complete demolition and reconstruction of the north grandstand, refurbishment of the stadium concourse and new technical equipment. Additional program requirements included new catering facilities, additional restrooms and new locker and storage rooms. The interior of the new north grandstand houses a five level building that also serves as load-bearing structure for a new upper tier.
The north grandstand building is literally the keystone for an enhanced functionality of Gottlieb-
Daimler-Stadium. Particularly the new second level food-court improves visitor convenience.
The new upper tier provides 2150 attractive new seats close to the playing field and serves as a visual counterpart to the upper tier of the existing main grandstand.

Bozen Library Center combines several library institutions for the trilingual region and a cultural center under one roof. The new library’s holdings will include about 1,100,000 volumes. It is expected to attract about 400,000 visitors per year.
The rapid development of information technology challenged the traditional concept of the library considerably. The library as an institution is supposed to be a center for different media, information, education and cultural exchange, as well as a meeting point in the city.
The design concept seeks to define the library center as a vital part of its urban context. It is an autonomous building that does not conceal its purpose but rather becomes a distinct part of public life through its inviting transparency. The building opens up towards the city and thus becomes part of it.

DaimlerChrysler Sindelfingen Expansion Masterplan
DaimlerChrysler invited five renowned architectural firms to develop design proposals to accomodate future growth of their Sindelfingen research and production facilities near Stuttgart.
The expansion of the 40,000 employee facilitiy towards the undeveloped area termed “Südlicher Mittelpfad” north of the existing plant had to be environmentally friendly and sensitive to the local microclimate.
The concept proposes a linear “science-city” that can freely expand to the east and to the west respecting the natural preserve north of it. At the transition from structure to landscape a sense of spatial transparency becomes tangible.
The southern edge of the development marks the conclusion of the inhomogenous texture of the existing plant and redefines the streetscape of the “Calwer Strasse” thoroughfare. A high-rise office building becomes the edificial and social focal point of the new development. All major connections converge here.

German Bridge Design Award 2006
The La Ferté Bridge is an important pedestrian and cyclist connection across a busy four-lane road with tramway tracks in the middle. It links a residential neighborhood to important local infrastructure like the school complex, public festival-ground and the local swimming pool.
The site conditions with a steep slope on one side of the road and a flat public park on the other were essential for the design of this asymmetrical bridge. The bridge has an even slope and curvature. It is supported by six slender columns. Instead of walking the gently sloped cyclist's ramp pedestrians can use a steel staircase in the middle of the bridge as a convenient shortcut.
The bridge is part of the surrounding landscape without producing a sharp divide or obstructing views.
