Curve-Fit Timber is a building system for architects and builders who want to create free-form wooden structures efficiently. It uses flat-packed, lightweight timber plates that are curve-folded on-site into load-bearing modules, solving the problem of high costs and resource waste associated with complex architectural shapes. It is sustainable because it uses renewable timber with low embodied carbon, minimizes material waste during fabrication, and features a modular design that supports disassembly and reuse.
