In the independant basement you can park a small car or a scooter/motorbike. The door can be opened.
The first floor is a kitchen/living room
The second floor is an office/bedroom with a bathroom.
You can easyly build an empty house if you want to.
Obviously you can change 1x8 and 1x6 parts with 1x3 1x2 and 1x4.
