Recent years have seen the implementation of the City Densification Project in the Krieau, an area within the Prater district of Vienna. A high-rise building, numerous office buildings, a residential building and a hotel – the Courtyard by Marriott Wien Messe – have been constructed on a building site of approximately 40,000 sq m.
The hotel structure responds to the concave and convex forms of the neighbouring high-rise buildings with a boomerang-shaped, curved eight-storey accommodation wing that projects over a single storey base.
Reception, restaurant, conference rooms and the hotel management offices are located within the all-around ceiling-high glazed base area. The rounded glass facade, which extends around the corners, allows hotel life to be experienced from the public spaces outside the building, and also in turn extends the interior space outwards so that there is a light airy atmosphere even when the restaurant terrace, which looks toward the future lake-side promenade, can not be used because of the weather.
The eight-storey hotel room wing with double-loaded corridors and 250 rooms is situated along the building's main axis to guarantee optimal illumination to both sides. From the north half of the wing the hotel guests have a view of the new 'Viertel Zwei'.
An attractive view in the direction of the Prater can be seen from the south and east halves of the wing. The facade of transparent and opaque elements is a key design feature of the hotel-room wing. The design of interchanging narrow light and dark stripes was inspired by the barcode, and bright aluminium sheet panels and dark window areas alternate with each other.
Displaced horizontally at different floors this interplay produces a simple, but far from dull, façade design that has a very individual appearance, especially from a distance.
