Wedge House

Bronze 2025

Wedge House

by Kiyoshi Sugimoto for Masato Ikuta

This design tackles a challenging site: narrow, steep, and with strict building limits. To maximize space within a 40% coverage rule, a three story mix of wood and concrete was implemented. The innovative wedge shape places living areas on the view rich second floor, with diminishing lower levels to ease retaining wall pressure. This design balances regulations, space, and scenic integration.
