About us

BA-AS is an Amsterdam-based office for architecture and urban design. Founded in 2020 by Christina Behrendt and Gijs Adriaansens. 

For us, the beauty of the built environment and the city lies within the synergy of the two diciplines architecture and urban design. We call this: architectural urbanism. 

Our professional experience spans from the urban masterplan to the architectural detail. The focus of our office lies on residential, mixed used architecture and urban design.
