Mr. Ambalal Himatal (father) and Mr. Amit Ambalal (son) wished to replace their old bungalow with a new house that reflected their lifestyle. After meeting several architects, they entrusted the design to Bernard Kohn, who understood the role of architecture as being most in tune with nature and closest to human experience. Throughout the design process, Kohn regularly visited the Ambalals, befriended them, and gained an understanding of their lives. As an artist, Amit Ambalal required exhibition walls in his home. Kohn therefore designed the ground floor to be very high, with zenithal light to highlight the artworks. Furthermore, the diagonal walls, reminiscent of a pyramid, serve to block light in summer and allow it to enter abundantly in winter. The house was once red with exposed bricks, but it has since been renovated and painted white plaster.
