I love those money trees in front! The concept of everyone sharing one big bedroom and bathroom is understandable, but I wonder if it will work in reality with your Sims. I don't think a couple will woohoo with other Sims sleeping in the room.
No, of course they won't. That's not a big issue. For single Sims (Recipe and soon Queen), they just find their fun via TV or whatever. The married couples Woohoo in the double beds when only they are in the room. Again, not a problem at all. It's just a question of timing.
And will they take a shower in the same room if they aren't married?
No. At the moment Girly is the only Man (heh heh, that sounded funny) that punches a clock. So, she has priority in the morning to clean up before heading to the Business office. Everyone else takes showers whenever, so it's not really too much of an issue. This simpler system of community living has been working really well.
EDIT: Oops. I forgot about Kareem. For now he's in the Business career too. I never concern myself much with spouses to be honest. But he showers at the same time as Girly with no issues obviously.
