Architect Marcel Raymaekers collaborated with sculptor Raf Verjans on this 1965 Belgian home in Tongeren which celebrates play via its treehouse design.

House C looks like an oversized playhouse thanks to its timber facade inset with circular portholes and stained glass panels, which slot between tall ribbon windows. It was built against a medieval rampart – Tongeren was a major trading post from the Roman times, and the town centre is encircled by historic walls – its boxy volumes orientate around a small, secluded garden while interiors retain their strong 1960s vibe with materials on show throughout.

These include soaring volumes, parquet flooring and a sweeping minimally divided floor plan, with living spaces set across 285 sqm. Local brick and sustainably sourced wood was used to construct the Belgian property and is the dominant material across the light-drenched interior volumes. Meanwhile, Verjan’s specialism in blacksmithing can be seen in its bespoke circular fireplaces, inset with a stove and grill.

Part sculpture, part home, House C is listed via Architecten Woning for €569,000 and is located in the heart of the medieval city, a short drive from the Dutch border.
