A brick skin seamlessly covers the cubed volume produced via these limitations — from the vertical exterior walls, over the sloped facade and attic, up to the floor of the roof terrace. The bricks form the outer layer of a double-shelled construction. The exterior shell’s brickwork references Gründerzeit construction methods and the materiality of the front building’s street-side facade, while its color spectrum quotes the tones of the surrounding facades within the courtyard. For this, a Brandenburg brick manufacturer fabricated 20,000 bricks in a range of six different colors: from off-white and yellow to orange-brown, pink, and grey.
