Four Leaves Villa | Weekend Villa in Karuizawa

KIAS (Kentaro Ishida Architects Studio) has designed a weekend villa in a forest Karuizawa, Japan’s Nagano Prefecture. Called Four Leaves Villa, the 225-sqm (2,422-sqft) retreat was completed in 2018.

In order to form variable cross section suitable for each function, roofs were designed as curved surface like a gently twisted leaves. Combination of a concave and a convex roof configures from a high ceiling’s expansive space to an introverted compact space. Every roof was designed as a Ruled Surface in which straight LVL joists were arranged continuously to form an organic geometry. Series of wooden joists are exposed on the ceiling highlighting its dynamic spatial characters of each living space.
