Roof trusses vs rafter, which is more expensive and can we still enjoy some storage use within the attic?
Answers: The span foot span is workable regardless of design from a builder's standpoint. It depends on the nouns but typically truss designed homes cost less to build or cost no more than stick built. Really, the pitch of your roof will determine the distance from the ground you need for all right headroom. Your designed could inform you of that question. Trusses CAN be manufactured and designed to accommodate your desired 6x20 attic storage space. I've instinctively incorporated that design over many garages. The bottom cord (joist) is 2x6 is lieu of 2x4 and the cross bracing is redesigned from angled bracing to vertical and angular bracing to create the space needed. Either instrument, truss or stick built joist & rafters, it depends on the roof pitch which determines the distance from the ground. Example: 20 divided by 2 = 10 x 8/12 pitch = 6' 8" overall rise less top cord (or rafter) and bottom cord (joist), which translates into smaller amount than 6' of usage headroom. Good luck with the construction of your latest house.
You are not going to have attic access beside trusses. Those have cross bracing. The benefit of the truss is that you do not own to worry nearly wall spacings whereas the common rafter design boundaries your room width or length. If room span contained by an "open floor" design is your choice, you should use trusses.
If you want pricing, those trusses are Standard and can be priced right at Menards, Lowes, or Home Depot.
You will find the cheaper to be Truss. Even though you might requirement a crane for a day or two That is the cheaper structure.
Many homes today are designed where on earth the upper level is also living space. Those obligation rafters.
Truss is the better choice when the "attic" is not to be used due to its strength and its cost pre-eminence.
I would use the trusses. They cost less and they collect on labor. You are right you will have 6x20 foot for storage.T.C. custom home builder with 30 years experience.
