A first-class architectural studio in Kariya, Aichi, Japan. Since 2008 we've been practicing wooden structural calculation, Passive House design, and thermal performance. We provide calculation outsourcing, design support, and second-opinion reviews for fellow architects and builders.
We handle the structural calculations actually needed in practice — allowable stress design, load-bearing wall checks, horizontal diaphragms, slenderness ratios. Also second opinions on complex plans and high-seismic designs.
From envelope calculation to primary energy, ventilation, and thermal bridge (Flixo) analysis — numerical work and design support to raise thermal performance.
Based on certification experience from the second Passive House in Japan onward, we support design of Passive Houses (and high-performance equivalents).
BIM-based duct planning, 3D detailing verification, drawing templates, and document formatting — practical support to raise studio productivity.
