Located in a secluded location, the GP House is a family home for six users of three different generations. Focusing on passive lighting and good air ventilation, the main feature of the house is its high ceilings that produce unique triangular forms. The height allows more openings allowing more sunlight to penetrate inside the house while also letting air circulating well. Hot air rises from the bottom up and escapes from the ventilator, making it efficient for cooling and the ventilation system.
