This could happen I suppose if there was a persistent leak - but for it to be that bad the building would have had t have been in a state of severe neglect for a long period i think! True enough, it might only take one pole to go for the whole roof to cave in but it would be unlikely to happen all of a sudden- I think there would be a chance to try a repair before complete collapse- hopefully the same for society as a whole! :) Im not sure what would happen</p> Hi Nick I think I understand your point but a single pole failing would be extremely unlikely- there is no reason to suppose one would fail unless it became completely rotten.

is each main pole of your reciprocal roof fixed into a common element such as a steel hoop at ther top? I wonder what happens if a single main pole fails for any reason. Much like a lattice truss, the reciprocal roof without a tensile common top element does a fine job of spreading the load but relies on every pole being perfect. You’ll notice that most buildings utilising conical roofs without a central support are designed with each pole fixed into a tensile ring so that a number of poles could fail without the roof coming down.

I’m a bit of a worrier and I imagine the weight of the whole roof relying on the integrity of one pole: which one, of course, would only be known in the case of a failure – the load only being spread elegantly between the poles if they are all in pefect condition.

By the way, I’m not a structural engineer but my family had a structural engineering practice for many years and the phrase in the design office was “never trust a truss on its own”.

Otherwise, a beautifully simple and elegant building!

Best wishes

Nick

Just wanted to say how much I liked this post. Our family is looking at more sustainable green living. Step by step we are trying to adopt a more natural lifestyle. I think that what you have done here is wonderful. Thanks for sharing.</p> Found your blog by chance today. Just wanted to say how much I liked this post.

I like the careful framing you did for the opening and your choice of plastic for the roof liner. Are you still without leaks? Any suggestions you'd offer to someone also doing a reciprocal roof with timber? Thanks for any suggestions!</p> Hi G, I’m loving your roof!

Finding myself in the land down under Aotearoa- New Zealand theese days, I finally resived my residency here, weehej! Your home looks amazing, now its long ago since I visited. Still from time to time I send you my thoughts to you and all the other beautiful people in Eire. I'm living on the south island in our home built house truck and yurt. I love it here.At the moment I'm buizze winter pruning apple trees.People here shout out in joy when I mention the Action plan and Kinsale.The word has spread! Much Aroha(love) from Pernilla</p> Kia ora(greeting in Maaori)Graham! just found you on the wide wide web…..
