Appearing to float above the landscape of Okayama, Japan, the Pit House was actually built by excavating six spaces of earth. Accommodating the clients’ desire to create a home with a deep connection to the earth, UID Architects organized the entire house around a circular living room, creating several interior garden areas that serve as an extension of the landscape.
UID Architects‘s main goal for the Pit House was to make the transition between the exterior and interior as seamless as possible. Multiple branch-like columns support the cedar floating box, while the concrete cylinder situated in the central area of the house acts as a both visually and structurally dominant element. The cylinder connects six types of floor levels. A staircase spirals around it, enclosing a circular bathroom and a storage closet.
“The concept is inevitably drawn from the request of the clients, and the context of the site. It becomes a subterranean room with little influence of the open air, and a relationship with the external surface of the earth”, state the architects.
The space seems to flow and gradually develop into different areas of the house. The cedar box encases the house and hovers above the sunken ground floor. Providing a glimpse of the complex spatial relationships behind the simple geometry of the box, a large rectangular opening reveals a recessed balcony behind the façade, which is a continuation of the L-shaped first floor.
