The most authentic choice of façade material was therefore terracotta brick. The play of different colours was intended to bring the architecture to life and give each individual building a unique appearance. “We wanted to give each building its own identity; firstly with a specific shape, and secondly, using the shades of the bricks,” says Avenier. The brick ornamentation alternates between monolithic sections and rather airy surfaces. To select the right colours, the team looked at the bricks from different perspectives and under different lighting conditions.
“You have to see the play of light on the product,” explains the architect. Ultimately, they chose titanium grey, silver grey and blue red, all of which vary in their shade depending on the intensity of light. “Titanium grey, for example, changes from a light, violet-coloured grey at sunset to a darker grey when it rains – so the visual impression changes depending on the weather.” Furthermore, the hand-formed bricks have irregular, slightly shaded edges that give the façades a timeless appearance.
