Building a Reciprocal Roof with Tony Wrench.


This is Tony Wrench's cordwood roundhouse den in Wales. Like many of Tony's homes it's based on a henge of roundwood timbers with the ends charred and daubed in pitch before being buried in the ground. The roundhouse cost Tony around £100 ($150) to build using timbers from the woodlands that surround his home and some reclaimed windows. It was built with the help of volunteers who came to learn how to build these beautiful homes, but specifically, how to build a reciprocal roof.

Building a Reciprocal Roof


A reciprocal roof is a self-supporting spiral of timbers where each timber rests on the next and needs no central support. It leaves a round skylight that brings light into the room. In the video right you can watch the construction support, known as a 'Charlie Stick' being removed from the den's reciprocal roof and left is a video tutorial from film makers 'Living in the Future' that followed one of Tony's many reciprocal roof workshops.
