The recently completed Villa X in Brabant (NL) combines solid and void in a geometrically minimalistic composition. By folding the front and back facades inwards, the open living space – the “void” – is fluently connected to the surrounding nature. Two closed blocks at both ends mark the “solid” private spaces, which contain the guest and private living quarters. These private spaces are covered by hefty anthracite concrete walls, with a smooth, reflective finish achieved by multiple layers of hand-polishing. The protruding guest room window is cast into the wall, appearing to have been pulled out from an elastic surface.
