There are many well-known buildings, especially in northern Germany, bearing the hallmark of ahrens & grabenhorst. The interdisciplinary team with headquarters in Hanover has worked on quite different, but all-in-all unique, buildings: from places of worship to hotels, from residence buildings to museums.

Building an annex building to the statemuseum‘ Ostfriesisches Landesmuseum’in Emdenwas not an easy task. Containing the region’s oldest collection the museum is
situated in what once was the historic town hall. Destroyed in the Second World War it had been re-erected in a modern style only partly reusing historic features.When ahrens & grabenhorst took part in a contest in 2003 – andwon it – to build an extension, this history had to be taken into account on the inside and outside.
