I think the black would go well in our living room and this wouldn't feel to crowdy in our place. we would want part of it to be built to accommodate the records or else leave that part out to keep our current record storage in place. Even just on one side of the door way this could hold all the books probably. It would make me so happy to minimize the footprint of the books and still have them handy.
bright turqoise blue cube built-in bookcases, massively high ceilings, decorative victorian plaster, bright white walls and rooms, painted blue hardwood floors, french doors with awesome transom window, old leather chairs...and dont let the painted library ladder on the right pass you by-it matches the book shelves... this house seems pretty awesome
