Even though I started this thread well over a year ago, I've realized that I've never actually submitted a suggestion for a condo design. Well, this post should remedy that.
This condo is designed for those who want to build in a large, indoor space who either don't want to spend millions of units building the space first in Smooth Dirt with Canvas Primitives, or feel constrained by the relatively small volume you're given with the Art Studio. The warehouse would mainly comprise of a single, tall room with a relatively large surface area for its floor and there are no windows on the walls or ceiling. All of the doors that lead outside of this room, both normal doors and giant garage doors, cannot be opened. The only source of light is a series of large light fixtures that are attached to the ceiling. There may be sections of the warehouse that are raised above the floor to accommodate for rooms such as the employee lounge, the manager's office, and electricity control room, etc.

Side Note: I already know that @TrappingGull had a similar idea with the empty convention hall posted earlier in this thread.
