This green-roofed carbon neutral home designed by Mark Waghorn Architects will begin construction in Cairn Valley, Scotland this month. The design was inspired by the sloping natural landscape of the project’s site. The energy-efficient home incorporates rainwater harvesting and purification, an air source heat pump, a wind turbine, and solar-thermal panels. Locally-sourced materials will be employed including reclaimed timber, and more unconventionally, wool sheared from sheep of the surrounding farms. A copse of trees and an outcrop of rocks will frame the view of the building, while existing dry-stone walls will extend through its interior.
