I like the little day bed and the window and beat board walls. day bed on plywood base with built in table. we would put the long edge further back for under the bed storage space. I also would want to paint it like white or something.
This bookshelf wall is the dream of every bookworm. How else will you store all your books in your dream home or interior? I always love when bookshelves go over a doorpost and all the way to the ceiling.
