Design
The Essence of GENSO’s Renovation Philosophy
Restoring Landscapes Rooted in the Local Community
We “return” Machiya to their original architectural roots, shaped by local history and climate.
Timeless wisdom and aesthetics enrich our modern lives, remaining beautiful across generations.

Material Selection
Choosing the right materials is essential to our architecture.
We select materials that return to nature as much as possible.
Natural materials possess a rich, quiet presence.
We trust their inherent power to shape meaningful spaces.
Through our architecture, we weave time from the past into the future.

A Richer Way of Living
While we value modern convenience, we also cherish time, nature, and the authentic.
We believe this balance is what truly brings richness to daily life.

Build
In-house Master Craftsmen
Our in-house master craftsmen ensure the highest quality of finish.
Unlike many other firms that rely on subcontractors, we have our own in-house carpenters. This allows us to maintain consistent quality and ensure seamless communication throughout the project.

Polished Craftsmanship
Taniguchi Koumuten is committed to employing full-time in-house carpenters.
This ensures we deliver the highest quality homes for every client we serve.
By working as a dedicated team led by a master carpenter, our in-house craftsmen accumulate the expertise needed to refine their art.
To truly realize a vision, it is essential to have full-time carpenters who share the same passion and skill.

Integrated Management: Our Carpenters Lead as Site Managers
At Taniguchi Koumuten, a dedicated team of in-house carpenters manages each site.
Unlike typical sites where fragmented responsibilities can lower standards, our master carpenters serve as site managers to oversee every detail.
By combining craft and management, we ensure consistent, high-quality construction from start to finish.

Rigorous In-House Inspections
Building codes only cover 9% of total housing quality; the remaining 91% depends entirely on the builder’s integrity.
To ensure absolute safety, we conduct over 100 inspections on every home based on our own strict standards.
These internal criteria are developed with a third-party agency to surpass legal requirements.

On-Site Client Confirmations
We invite you to visit the site for personal inspections during construction.
