Three new duplexes are being built behind the alley from where I live.
They dug out the basement and put in gravel, then poured cement only around the edges for the poured cement walls, which are now in.
I figured they'd pour the rest of the cement later, but no, they are just going ahead and building the houses...they have the first floor going in now.
Are houses no longer using concrete basement floors...or what?
