A calm penthouse unfolds from an attic shell, spread over two levels: an open living area with a bespoke joiner-made kitchen; a clear oak stair as a spatial motif; overhead, a deep-blue mezzanine like a sky suspended above; and a roof terrace with broad views across Berlin. In parallel, serious legacy defects were addressed — from saturated roof insulation to improper steel connections. Everything was realised while the building remained occupied, without façade scaffolding and without a site lift.
