150 m² Colonial Steel House – 3+1 Single Storey

The 150 m² colonial style steel home is designed with wide eaves and stately colonnades specifically optimized for Mediterranean and warm regional climates. Instead of conventional plaster, an advanced climate-adaptive coating system (silicone-based, reflective, UV-resistant with a 10-year warranty) is applied, actively reducing summer heat gain on roof and wall surfaces.
