This house was built without a single drop of cement or steel. It uses interlocking perlite blocks that snap together like LEGO, no glue, no mess. The system is fireproof, lightweight, and needs no extra insulation. A computer calculates the exact number of blocks needed, so the entire structure goes up in just one day.

The 3E System uses perlite blocks that are assembled without mortar, enabling fast, clean, and efficient construction. It provides thermal and acoustic insulation in a single step, making it ideal for sustainable projects and self-building processes. #SustainableConstruction #3ESystem #EnergyEfficiency | Architecture & Engineering
