Closets are an often overlooked and under-appreciated part of our lives. While the closet at the front door requires only the basics, we find that the deeper into the home that the closet in question resides, the more particular it's function becomes.
The master closet comes to mind immediately, and no matter it's size, some simple questions can quickly determine the accessories needed to make it functional and user friendly. Obviously, types of clothing determine large portions of the layout, but then we look at shoes and accessories, belts and ties, purses and even jewelery. These things all need their own space for functional/simple, access and use.
