House modeling

I used 123D Design to design this house(100x100). This house has 2 rooms, 2 bathrooms, windows, living room, kitchen,hall. Hall of the house is wide enough to put the storage closet. So, while living in this house, I can store something up in the storage closet. And I can use rooms as I want. This is my first work for using 123D design. When I makes much more works of 3D printer, maybe I designs better things. Design this house more better if you have a good idea to make advanced design. Thanks for looking my work.
