I'm planning to demolish a timber framed lean-to and rebuild a larger version which will be a general storage area/glorified shed/utility area.

I'd planned on rebuilding using a timber frame then insulating and cladding but have been reading about these SIP panels and they look interesting and would make the job a lot quicker and easier I reckon.

I've already laid a course of blocks to mark out the area which and will install a DPC and a sill plate. Would the panels simply sit on this?

The size of the new lean to will be 3.6 x 4.2m with a single pitched roof. Is it simply a case of having four panels cut to size and then joining them together, or is it slightly more complex than that? Would I need to specify spaces for doors & windows or would I be able to cut these myself?

Looking for any tips and advice. Thanks in advance.

I've just had a granny annex built with SIPS, in my case they fitted into a timber frame (the frame was built up as they went along). The roof was also constructed of SIP panels, then additional insulation added inside. Additional info in this thread http://www.pistonheads.com/gassing/topic.asp?h=0&a...
