Living with roommates and large households: complete walkthrough
Decide who needs what space
Count household members and their schedules before choosing the lot and bathroom capacity.
Reduce bottlenecks
Place multiple toilets or distinct workstations for busy large homes, and test narrow hallways.
Use individual task priorities
Pause to manage urgent needs and keep an eye on Sims who are not actively selected. For a six-person household, test the morning rush as several Sims try to prepare meals and reach the bathroom. If routing fails, look for a single tile bottleneck at the entrance or kitchen before buying more expensive appliances. Assign the most time-sensitive school and career preparation first so one member is not late because everyone else is using the same doorway.
Build relationships gradually
Shared living allows many interactions but also creates opportunities for accidental conflicts.
Protect important saves
Moving, splitting or merging households changes living arrangements; save and confirm where money and objects went.
