A part-converted roof shell becomes a calm penthouse across two levels: an open living area with a bespoke joiner-built kitchen, a clean oak staircase as the spatial motif, above it a deep-blue maisonette floor and a roof terrace with a wide view across Berlin. In parallel, serious defects in the existing fabric were put right - from waterlogged roof insulation to faulty steel connections. Delivered while the building stayed in use, without a façade scaffold and without a construction hoist.
