Our new house has a lot of storage. When we first looked at it, it kept me awake the first night because I knew I loved the house, but I couldn't think of how, since the house didn't have a basement, we would be able to get all of our stuff put away. We went back the next day and I took an inventory of the storage space and quickly found that we had enough (probably too much).
Each of the upstairs front rooms have dormers and to either side of the dormers are storage rooms (with little half doors). Augusts' room has two of them, but they're unfinished (as shown in the figure below).
