New Apartments and Commercial Buildings
The Service Industry DLC adds six new structures to your city-building toolkit — three apartments and three commercial buildings — in two base sizes, 2×2 and 3×3.

| Building type | 2×2 designs | 3×3 designs |
|---|---|---|
| Apartments | 1 | 2 |
| Commercial buildings | 1 | 2 |
Mixed-use buildings
Enable the Apartment and Commercial Buildings Have Retail Space option and the new 3×3 buildings can house large retail establishments — department stores among them.

Putting retail directly inside residential and commercial buildings lets you build genuine mixed-use districts — more economic activity in a smaller footprint, and more convenience for the people living there.
