A former workplace for a stonemason is accessible by a gatehouse along the Leo Tertzweillaan in Gentbrugge. The site has been refurbished with a cluster of new residential units and small workshops around a central square. The client owns a portion of the site whoch consists of a concrete structure adjacent to a double height steel structure. The design leaves the existing structures intact and adds a third, light wooden structure. A compact residential volume of two floors is place under the roof of the high shed pushed to the side walls. The slabs of the concrete structure is removed to create a walled garden. The existing concrete structure is preserved in the garden and is copied in the wooden structure of the house.
