Planning Upstairs: SJ and JP Bedrooms

We are in the market for good ideas for the upstairs. So far we have lots of pictures for SJ and JP's room/rooms. We are thinking small, with good storage. SJ would like a small, nook like room with an older feel. JP likes the idea of yet another bunk bed (can't decide if he would use top or bottom) and is also thinking small. In reality, we only use our rooms for sleeping and getting dressed so a lot of space would be a waste.
