Among the accolades received were the Maximum Construction Number Award, the Three Consecutive Growth Award, a recognition for achieving 700 total constructions, and second place in the S Group Competition.

What Is the SW Method?

The SW Method, developed by LIXIL Corporation, is a housing construction approach characterized by high airtightness, high insulation, and high seismic resistance, all based on a wooden frame methodology. This construction method features a monocoque structure that integrates high-performance panels to provide resilience against natural disasters such as earthquakes and typhoons. The careful design minimizes the temperature differences within the house, ensuring a climate-controlled environment supported by a planned ventilation system to maintain clean air, thus leading to a healthy and comfortable living experience.

In addition to adopting the SW method, Seizu houses incorporate the hybrid water heater
