Penthouse

Penthouses are new additions in The Sims 3: Late Night. They are fixed-size lots on top of Skyscrapers. They can be residential- as well as community lots. You can see people moving in or out but virtualy you are the only one living in a penthouse

Penthouses are similar to apartments in The Sims 2: Apartment Life, but do not feature the whole social experience of living in a community, your active Sim is the only one playable sim living in the building where your penthouse is, however NPCs will often live there too and we can see them sometimes walking to the elevator and locking doors, you can actually talk to them and you can ring their bell to get them out of their rooms and then you can socialise with them. They have been compared to the "Shell" buildings in World Adventures such as the pyramids. Apart from your residential space, there is a lobby with an intercom (to allow visitors to talk to you on the top floor) and an Elevator.

Penthouses are moderately-priced to very expensive and come in either one or two stories, depending on the price. It is not possible to make extra room, nor can you edit the existing walls. You can place pools on elevated floors in penthouses as well as windows as the siding in pools, though it is unknown whether this can also be done on normal residential lots.
