Hello. I need help in sizing a TJI for an attic I plan on making in my
existing garage.
The garage design/layout is such. I've been told it is a cottage style
roof system. There are no trusses. The roof is shaped like a pyramid.
There are about 8 or so 2x4s that span the width of the garage. I
assume they were for holding the walls true during/after construction.
Other then that the attic space is completly void. The exterior walls
sit on a 8" concrete footing. Overall garage is in excellent
condition.
My plan was to build an interior wall and roof system on that 8"
footing, inside the existing walls. The joists need to span 21 feet.
The attic space is purely for storage, but needs to accommodate me
walking around up there.
Anyone have experience in this area, offer some guidance? What size
TJIs do I need?
