Ivy House is a residential project completed in 1979 located in Yokohama, Kanagawa Prefecture, designed by the Musha Eiji Laboratory. This architectural work exemplifies the design philosophy of its era, showcasing thoughtful residential planning and spatial composition. The house derives its character from the presence of ivy, which integrates natural elements into the built environment. The design demonstrates careful consideration of how climbing vegetation can enhance the aesthetic qualities of a modern residence while providing practical benefits such as improved insulation and visual softness. This project represents an important example of residential architecture from the late 1970s, reflecting contemporary approaches to blending nature with domestic living spaces in urban Japan.
