Getting there

Progress report on the odd buildings from almost one month ago.
The doors are in, so it's safe to say they are getting there.
I have discovered that they are going to be 7 grade 7, student, studio apartments.
It just gets stranger.
I count 2 building with 3 floors, presuming one apartment on each floor. So where does flat number 7 go.
Also the doors you see on each level, there are matching ones in the other block, open into mid air, apart from the bottom ones.
