hi I notice that you have a gabled roof, can you use that space for storage, me I hang my models from the ceiling some with wings attached larger ones without wings on, I have a racking system where I store the larger wings. One thing that I find is a must are lots of work area's to mount band saws, piller drills and other power tools. One thing I have done in my workshop is to get two cheap chests of draws & put a chip board top across the two, lots of storage space in the draws. hope this has been of some help.
