Matthew Barnett Howland, Dido Milne and Oliver Wilton used cork blocks to build this house on a small island in the River Thames in Berkshire, England.
The dwelling, called Cork House, was designed by Howland, Milne and Wilton in response to the architecture industry's impact on biodiversity, greenhouse gas emissions and reliance on single-use materials. The house comprises five silver-grey pyramids, which emerge from the surrounding plants, trees and streams. It is constructed almost entirely from sustainably-sourced cork blocks supported by timber components and built without cement, glue, plastic insulation, plaster or render. The structure is designed so that in the future it can be easily dismantled, reused or recycled.
