It's pretty common on the west coast.
Dad has his Porsche on the single garage and wife and just-got-my-drivers-licence daughter have their junks on the other? :P
I guess the outside pic doesn't have any lightmaps calc'd ans applied yet?
Scale and such is bit off, but otherwise it looks to me game-good. Having a BA in Architecture some things seems to me bit out of / wrong scale like:
-Work chair is usually 40cm * 40cm... yours look either too wide/deep or the seat is too low.
-All ceiling look to be too low, usually they are ~3m
-Couch and table seem to have mismatching scale too
