New life for IKEA furniture from SUPERFRONT. To Australia they only ship handles and legs. Otherwise they provide possibilities for upgrading your Ikea furniture with cabinet fronts for a custom "Ikea hack" look.
Floating bookshelves, these are bookshelves I like. Looks like you could do this with an IKEA kitchen wall cabinet minus door and turned horizontal to mount. IDEA for narrow wall next to our kitchen wall
This is a perfect combo of my two favorite ideas for that space under the stairs leading to the basement. A reading nook AND book storage and shelves . assuming that there is enough space for this there.
