I was looking at all of your mini blogs and got inspired to work on my house:
I turned that bottom left room into the laundry/utility/junk room.
The place where work gets done and odds and ends of sports equipment gets stored.
I have a couple of these types of rooms in my house but they are not nearly as tidy as this one.
