As a result, over the past three years, 41% of our new graduate hires were women, and 65% of our employees were in their 20s to 30s. (*Results as of April 2024)・Overwhelming results-based system

In our general contracting business, which focuses on housing complexes made of reinforced concrete (RC), we strive to provide high-quality buildings while optimizing construction costs and construction periods. For some projects, we also use the design-build method, which covers everything from design to construction.

In addition, we support the creation of homes with excellent design by providing interior coordination sheets created by a design specialist team.
