Sol House proves that preserving heritage and embracing sustainability can go hand in hand. This Californian Bungalow's interior has been ingeniously reconfigured to minimise operational energy, all while respecting its original street presence. The result is a home that thoughtfully nods to its past while performing with exceptional energy efficiency, thanks to principles like cross ventilation and thermal mass, coupled with sustainable materials. The innovative Habitech pre-fabricated wall system was instrumental, dramatically reducing build time and creating a highly insulated, cost-effective living space.
