Crossway Passive House: An Unbelievable “Eco-Arch” in the Countryside

Crossway Passive House: An Unbelievable “Eco-Arch” in the Countryside

Architect Richard Hawkes of Hawkes Architecture, renowned for his sustainable designs, built his family home in the English countryside using Passivhaus (passive house) techniques. As mentioned in the British online magazine, building, construction, design, “the iconic feature of this pioneering house is a scarily thin soaring arched roof. Made by gluing clay tiles together using Plaster of Paris without any formwork, this in turn supports over 100 tons of soil which is now host to a thriving wildflower habitat. The house has incorporated the country’s first Solar PV-T system, harnessing the sun’s energy as both heat and electricity and a phase change material heat storage system.”
