Hi all, great forum you've got here! Seem to always pop in here when i need to do some research on something, but thought i better join up (and in) as im currently doing an extension (mostly myself apart from bricky) and have a few question that i could do with some help with!!
This regarding a flat roof and the joist layout, wall plates etc. As i've never done roof joists before im a bit stuck on the layout and if wall plates are needed and where the outside joists are situated.
The extension is 10.6 (width of the detached bungalow) x 5.5 metres, back wall is the existing bungalow, im going to be attaching a wall plate to the back wall with joist hangers, using 6 metre lengths of 47x225.
The main thing i cant get my head around is the wall plates! Im pretty sure that i need one on the top of front inner skin wall to take the joists and have something for them to fix too? but do i need them on the two side walls aswell?
Also the outside joists, do they sit on the innerskin wall/wallplate or just inside the wall?
Getting really confused with it and can't seem to find much online to point me in the right direction. Anyone got any advice.?
