**UPDATE**
I have recently built a base design for the apartment/skyscraper building in the city.
Here is a shot of the entire thing

and another view of the building

The lobby or ground floor consists of a checkin desk, a small library, some flowers, and a ladder that allows access to other floors.

and another view from the desk

The first living floor has 4 5x5 room apartments.
There is 1 shared balcony for the entire floor.
Currently there are 4 floors of this in the building.
Here is an image of hallways

and another of one of the rooms

Here is a picture of the shared balcony

The next design has each floor split in half
There is one shared balcony
Each apartment gets a private balcony.

Another view in the other room

The last design features apartments that take up the entire apartment floor

And last is the roof which features a minecart track, 8 miniature trees, and a small pond.(Mostly for decoration purposes)

Here is a helpful note, you can buy out multiple rooms in the apartment buildings and combine them if you want. This can also by done if the rooms are above or below each other.
More plans and features for the town:
Cactus, wheat, reed, melon, and pumpkin farm.
A subway to connect to the main line on the map.
A mall, with trading booths.
A formal town hall.
A suburban section for people who want to build there home.
A section where people can claim a small home for temporary shelter until they are able to purchase a more permanent home.
Also, just some rules about the area.
NO TNT
NO LAVA, unless you consult me about it.
NO FIRE, unless you consult me about it.
NO GRIEFING(This should be obvious by now)
And no mining unless you are making a basement for you home which at the moment there are no limits. There might be limits when the subway is being built if it is not above ground.
Once again, if you want to help build the city, please leave a reply below this post.
All donations are greatly appreciated and also result in a discount on a lot/apartment.
