Yeh if I move the whole ground floor foot print back onto the solid ground I can use a timber frame and as suggested below more of a light weight concrete steel supporting mechanism for just the decking overhang .

Thanks Russell, that would actually work with the site . There enough room to put the entire first floor footprint apart from the Balcony on solid ground. Just means less garden space which I can live with , yeh, less concrete and steel , less co2 & less 💰

Dam, I was hoping to keep the Carbon footprint on this as low as possible, guess its back to the drawing board on that.

That glazing, being triple gonna be expensive, the view justifies it though:) Thinking of a Louvre to mitigate the overheating problems. I'll have to make some calculations on how many windows will require shading and also the optimal overhang too.

its a tiny level plot so brining it forward like this gives so much more floor space, yep rain water to consider, harversting tank at the rear and an exit to be considered, I like Gus's idea on that

Thanks Gus, really appreciate you taking the time to think about these details. there going to be a rainwater harvesting tank at the back taking the roof water, then need an exit for when thats full. To keep it minimalistic, that idea of running the drainage inside the columns is definitely one I'll bring up with the architect.

Thanks John, I knew I'd get some invaluable comments right off the bat. Yet to go to a structural engineer and yeh prob take your advice and save some serious £

Hi guys, I intend to build a single floor frontal glazed SIP passive house inspired house on a hillside cantilevered in N Wales UK. If anyone has done a similar cantilevered project with SIP's, please let me know. Many thanks. Pic attached for ref
