To comply with the design specifications on the one hand and to create modern architecture on the other, van Velsen opted to use façade panels. The panels are made traditionally from heavy clay ceramic. Thanks to the diamond calibration, the panels offer a suitable solution for a modern combination of materials with glass and steel that is geometrically accurate to the millimetre. The architect chose two varieties of Terzo panels with two or three dummy joints. The panels with three dummy joints have the look and feel of flat facing bricks, while those with two dummy joints create the optical impression of large tiled surfaces. Randomly placed, a light, geometric pattern emerges. The concept is complemented by a surface that is chosen for its lively design, in changing shades of sand colours. No two panels look alike.
Gooiland is a region in the Netherlands with a landscape shaped by moors, woods, meadows and small lakes. For this region the architect Koen van Velsen designed a new and modern office building, which, in line with the wishes and specifications of the neighbourhood and the building authorities, features a gabled roof and brick-built exterior walls.
