Hopefully these are the first of many for ZOM Living, looking at their website they do a lot of downtown high rises in Florida, some 40/50 stories. So maybe eventually they will do one downtown Phoenix.

Biltmore: 300 units on 2.9 acres can be achieved with a 4/5 story wrap easy
Scottsdale: 749 units on 3.7 acres means they are trying to do towers probably around 8-10 stories to make that work. They mention 2-3 buildings.
Desert Ridge: 600 units on 26 acres, no idea what they could be planning here. The 20 acre piece (zoned commercial) is NW corner of 56th/Loop 101 and is wrapped on two sides by City North development and 6 acres is across the street, East of 56th (zoned R-1 residential) and an awkward shape (narrow triangle).
