Design Solution: The house was designed by 2009 Design Vanguard OFFICE Kersten Geers David Van Severen to maximize the site’s surface area on one floor while adhering to regulations and ensuring full accessibility for a child in a wheelchair. To achieve this, the firm opted for an octagonal design, which provides an efficient layout and seamless flow between spaces and ensures that all essential family functions are accessible on a single level, minimizing barriers and optimizing the use of space.

The ground floor serves as the family’s main living area, offering accessibility and comfort. One quarter of the space is dedicated to the living room, creating a central hub for social and family activities. Individual bedrooms, each with its own en-suite bathroom, are found on three sides of the octagon. The remaining sections include the kitchen, a pool area, and the entrance to the duplex, which leads to the nanny’s quarters upstairs. The second floor, separate from the ground level, accommodates guest rooms and the nanny’s living space, ensuring autonomy while maintaining integration within the home.

Structure and Materials: The house’s structure consists of a square concrete basement inscribed within the octagonal ground floor plan. The ground floor walls integrate concrete columns that support a circular concrete beam that carries the roof, which includes four large pots for vegetation. The second floor is constructed as lightweight wooden roof volumes.
