For the new building of a mixed used complex at Amsinckstrasse in Hamburg Hammerbook a volume was developed that strongly reacts to its urban surroundings. In its basic constellation the building follows the orthogonal grid of Hammerbrook. It consists of three long volumes that gradually rise up from five to seven to eleven stories towards the north. The shifting of the volumes adjusts the building towards Amsinckstrasse that traverses the rectangular grid in a curvy diagonal. Thus, a protected outside area is created towards the canal Sonninkanal.

Apart from its timber structure the building contributes to a sustainable development of the city with its high flexibility that ensures a long-term usage even if functions might change in the future. Therefore, neither does the building show the intended functions in its facades nor in its basic inner structure. Rather a building was designed that offers a basic structure with an economic column grid that can be flexibly used for many different functions.
The open and high ground floor activates the public space and opens up the view towards the outside space at the canal and the Sonninhof behind.

Because of its exposed situation next to a highly frequented street and due to the often-rainy weather in Hamburg, the timber building does not show its materiality towards the outside but is covered by a facade of ceramic tiles. As one uniform and clearly articulated structure, the façade unifies the three staggered building volumes. It shows the load bearing structure towards the outside by featuring wider dimensions in the lower floors than in the upper floors. The diminishing upward motion of the façade grid creates a differentiated impression despite the economic unity.
