get some sets of cube shelves..
get some floating shelves that match the width of the alcove as closely as possible..
get some furniture legs..
and just put it all together!
Attach the legs to the bottom elements and then stack everything up in whatever combination you choose. The floating shelves are NOT attached to the wall using the supplied brackets. Once happy with the layout attach the top-most shelves to the wall with some brackets. Not recommended for households with small children with climbing ambitions.
