WWilts Posted July 31, 2021 Share Posted July 31, 2021 (edited) Lean to in the recess formed by 2 existing walls. For various reasons, it is exempt from BR. Outer skin (side wall) will be stone masonry, tied to the posts. Cavity 25mm with breathable membrane. Front elevation largely glazed, for various reasons. Roof covering OSB3, breather membrane, counterbattens & battens, slate. Any obvious flaws in the design? Is it crying out for any changes (eg, more purlins?) Would you insist on structural calcs? Would a 450 x 450 mm trench fill foundation suffice to hold up the stone outer skin, 2.6m tall? (soil texture is sandy gravel, good load bearing) How would you fix the timber posts to the foundation concrete?

I would be installing a course of blocks on the founds, DPC a treated timber sole plate, then your stick frame. Also a basic concrete or screed floor with DPM. Got somewhere for roof water to go? What length are the roof joists? 2 Link to comment Share on other sites More sharing options...
