4 rooms house of 316m² in Waterloo

This exceptional modernist villa, built in 1959 as the private residence of renowned Belgian architect Jean Cosse (), represents a rare opportunity to acquire an authentic architectural masterpiece. Widely regarded as one of the leading figures of post-war Belgian modernism, Jean Cosse developed an architectural language in which geometry, light, landscape and spatial harmony merge effortlessly. This property is among the finest expressions of that vision. Designed according to a rigorous modular system, the house unfolds through a sequence of carefully proportioned volumes and living spaces. Its façades feature a subtle interplay of squares, rectangles, solid surfaces and openings, creating an architecture that is both understated and powerful. Inside, expansive glazing floods the interiors with natural light while establishing a seamless connection with the surrounding garden. Timber ceilings, original built-in elements, natural materials and refined level changes contribute to a warm and sophisticated atmosphere. The generous living room, centred around an iconic fireplace, forms the heart of the home and flows naturally into the dining area and kitchen. The current owners, including architect Joyce van Nieuwerburgh, have undertaken thoughtful renovations that enhance comfort while fully respecting the integrity of Cosse’s original design. The bathroom, kitchen and extension have all been carefully updated. Between the various volumes lies a beautifully landscaped garden where architecture and nature interact in perfect balance. The former drawing and studio spaces offer excellent possibilities for a professional practice, creative studio or home office. A truly unique opportunity to live within a timeless work of architecture by Jean Cosse.
