The Sinus House. A building on the move. Mobility plays a central role in today's everyday life and has also become a social issue. Especially "green" mobility is coming into focus. Besides to the expansion of local public transport, a classic means of transport is coming to the fore. The bicycle. The bicycle is a popular means of transport for all age groups and is being used more and more. At railway stations, but also in other places, this creates the problem of limited parking space. Bike safes now offer a remedy for this. They offer many parking spaces in a small area without being conspicuous in the cityscape. At Darmstadt's main railway station, three such towers are linked to one building. A building where pedestrians, cyclists and public transport meet. An interface for public life. A place for movement, but also for resting and taking a break. Also to the bike safes, it contains a small café and a small bicycle workshop. The building integrates three underground parking towers so that they are hard to notice from the outside.
The design also adapts to the movement of the site. The footprint is an elongated rectangular, starting with the café, opening towards the centre for the three bike towers and ending with the bike repair shop and the rental shop. The café side faces the main railway station and its entrance, while the bike workshop and bike safes are away from the main traffic routes. The café is thus located at the intersection of the traffic routes of the main station, bus stops, Kinopolis and the direct pedestrian routes leading off Rheinstraße. The basic form of the building was chosen to be simple, only to become expressive in its outer form. The elongated structure is covered by a wave-shaped roof, which intends to pick up on the movement and dynamics of the use. The wave shape can also be found in the floor plan.
