This renovation project reimagines a single-family house in Genval by optimizing its layout and expanding its living spaces. The project includes the elevation of the existing house with the creation of new rooms and a winter garden. The ground floor of the existing home has been completely restructured, with interior partitions removed to create an open and rationalized plan. A full additional floor has been added to the house, introducing new rooms that increase its capacity while preserving the architectural coherence of the original structure. A highlight of the extension is the integration of a winter garden, which bathes the interiors in natural light and creates a connection to the surrounding environment.
