Almost every house has them, those small awkward spaces lurking around every corner. Most of us can't afford to give up that space and are looking for ways to make it useful. Here is an idea that you might find helpful. This is a space that was on a stair landing of a house that I recently worked on. We thought it would make a great little reading nook, so we added a little window seat, with storage below, and then some handy book storage all around. Some ways that you can dress up this space:
Paint the back of the book cases an alternate color
Add "feet" to the cabinet so it has more of a furniture type feel
Create a valance over the top, it will unify the whole piece, and that sense of a "ceiling" will make the seat more cozy.
