Build a Wall Niche I had one of these in my other home. In the living room, it was great for photos and knickknacks.

pull out cabinets - for ALL of your storage needs! You could hide all your stuff and still shelve things. It would only take up about 3 feet from the wall of floor space and it would act as insulation if you did it on an outside wall. and depending how it's done furniture could go in front of it most of the time.
