A reciprocal frame roundhouse is a beautiful structure, here is a film made by one of our course participants of my husband Nigel Lishman’s course run this year in July.
As you can see the frame is actually quite simple, leading to a very beautiful roof structure. This shelter took only 8 days to build with 8 people. People use this type of frame for anything from a shed to a house. For more info and links visit the Plas Helyg FB page.
