Using space wisely is the hallmark of good design. I love nooks and crannies when they are utilized, but I do not like them as junk storage spaces. More often than not people are intimidated by the strange spaces in their homes. These little areas like space under the stairs and eaves of your home are wonderful space to get creative! If you think about a ship every area of the interior is used for living and storage, how can you use this model to help make use of your spaces?
In the room above we use built-ins to make use of all the space under the eaves. We had a desk area built with shelves above and then tired the window bench into the desk. The window bench gave us storage and a sunny spot to sit and read. The desk area is a wonderful homework space.
