Adding Conservative Apartment Tower (2x2)

A bit goody rich but also offers the advantage of 2 houses per square density.  The stone filler on the exterior sides of the elevators will be partially filled with emergency stairs when z-levels are in.  The upper floors will have multi-bedroom apartments and I'm a bit undecided about a basement laundry/utility.  

The Modernist Apartment tower will have a less repetitive interior/exterior and forgo the geometric shape while still having the same components in each suite.

The locked front doors are a bit of a surprise that I didn't remember when I was play testing. 

Pic will be in the OP here, soon:
