I'm currently building a 20 foot x 40 foot workshop / garage beside my house. So far, I have built it up to lintel level as a cavity wall using 4 inch concrete blocks with a 4 inch cavity using stainless steel wall ties But now I am unsure how to proceed with the roof.
I need the roof space to be pretty free of structural members as I plan to build a boat in there and I need the headroom. I would like the roof to be insulated, drip-free, and to have lots of rooflights.
Any ideas? Please help me! :lol:
