A spacious mansion in Antwerp's belle epoque neighbourhood of Zurenborg is being renovated. Between renovating the rooms under the roof and replacing the rear extension, a giant bookcase is also being designed and built. Everything in this house is grand. In the children's attic, 3 bedrooms with mezzanine are organised behind a house-wide wall of closets. What remains is a children's lounge connected to the sleeping mezzanines via a large window on top of the closets. On the ground floor, the familiar Flemish-style rear extension is replaced by a sober, elegant variant using recuperated marble from the Brussels' former North Station. We create a massive sculpture in the rear façade in which benches, countertop and kitchen furniture come together. The height is oversized so that it continues from the main building.
