Our new house will have an area that we want to put a potted tree. I have considered bonsai's in the past but never had the place for one. The area is about 3 ft wide x 4 ft deep with a ceiling about 12 ft tall. One side is open, one side is stairs up to 3 ft and then open above, and the other 2 sides are wall. There is a south facing window a couple feet away. Would like something that we would maintain at around 7-10 ft tall with a spread of around 3 ft.

Any suggestions and/or pics? Anyone else have a tree this large in their house?
