Residential Buildings These are buildings which comprise of several rooms which are used mainly for residential purposes. The building owner can also designate specific rooms by placing furniture or equipment, for example, buying and installing gym equipment in a room can designate it as a Gym Room. Likewise, installing surveillance equipment and a Missions Briefing Console will assign a room as the Control Room of a Team Base. Note: Unlike shops, you can build several buildings of the same types in the same city, even the same location.
