Along with the mandatory compliance with energy-saving standards in 2025, the special exception for Category 4 has been significantly reduced. After the enforcement in April 2025, structural examinations will also be conducted for two-story wooden houses, except for some small-scale buildings, and the attachment of structural-related documents will be mandatory. Our company offers services for structural calculations (allowable stress calculations) and wall quantity calculations (frame calculations). We also accept consultations solely for special foundations such as "cantilever foundations" and "deep foundations." Please feel free to consult us if internal handling is difficult.
