Vaulted Ceilings & Natural Light

Roofspace Conversions and Buildings generally have become less efficient over the decades. As they have become larger and the families leave the house during the day to pursue outside activities, and as natural light and ventilation are minimized in favor of central air conditioning and electrical appliances. Our Roofspace Conversions use new technologies that optimize natural energy resources for what we call a net zero energy house design.
