This is a project page for a renovated Kyoto townhouse (machiya) concept, not a specific property for sale.

This page describes the "Korekara no Kyōmachiya" (The Future of Kyoto Townhouses) project by fikaso and Hachise. It focuses on a renovation case study aimed at achieving high insulation and airtightness in a traditional machiya, which is typically difficult to retrofit. The article details the construction methods, including creating ventilation and insulation layers inside the existing walls, using resin sashes and insulated double-pane glass, and achieving impressive thermal performance metrics: ceiling thermal resistance of 5.6, wall resistance of 4.6, and floor resistance of 2.2. The C-value (airtightness) reached 1.3, and the UA-value (heat loss coefficient) was 0.41, exceeding standard energy-saving benchmarks. The narrative includes a discussion with the construction company president and the project designer about the challenges and benefits of high-insulation, high-airtightness housing in a traditional structure. The page also includes a photo gallery showing various rooms, such as the genkan entrance, LDK, tatami lounge, pantry, study, and a tsuboniwa courtyard garden. This is a conceptual project showcase, not a listing for a specific property on the market.
