Specialists in Passivhaus and Energy-Efficient Building
Over 25 years of pioneering sustainable construction in Herefordshire and beyond.
Welcome
Our commitment to energy-efficient building began long before it became mainstream. Since the mid-1990s, we’ve dedicated ourselves to crafting buildings that are not only structurally sound but designed with the future in mind, using less energy, creating healthier indoor environments, and standing the test of time. What started as a passion for good craftsmanship has evolved into a lifelong pursuit of sustainable excellence. We’ve grown with the development of the Passivhaus standard, integrating its principles into almost everything we do, and we see every new project as a chance to learn, refine, and push things further.
Our Path to Sustainable Building:
-
2007: Adopted zero thermal bridge detailing using Passivhaus principles
-
2010: Completed a PHPP-designed extension targeting 30 kWh/m²/year
-
2011: Built Herefordshire’s first certified new build Passivhaus
-
Ongoing: Continuously refining our detailing, techniques, and efficiency
