Renowned architect Richard Hawkes' Crossway Passive House, completed in 2009, gets another look on this week's episode of the British TV series "Grand Designs."
"The iconic feature of this pioneering house," writes Building Construction Design, "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 3,000-square-foot home is packed with energy-efficient technology, including 580 liters of phase change thermal storage and DuPont Energain
PCM panels in the south-facing rooms.
