The Sims 3 Guide - Sunset Valley
While the above is all well and good, it is not unreasonable to want to alter Sunset Valley slightly. As well as simply moving your own family around to other lots, and perhaps picking out a different family to play as, you can change more critical elements of Sunset Valley to suit your wants and needs.
To access the Edit Town feature, use the Options menu.
There are a few key areas of Edit Town to explore:
Changing Positions: You can alter the location of community locations in the town centre, basically shifting the grid map of Sunset Valley around. Obviously you can do the same with residential properties, perhaps making the map more convenient for your family, or simply more interesting.
Changing Purpose: One of the most exciting things to do in Edit Town is to find unused plots of land (i.e. those you could build a house on in Build Mode) or evict the tenants, and then create a new community location. How about a library with a swimming pool in it? Use the cheats to fund these endeavours if you must, but the thrill of knocking down a house and opening up the area to the rest of Sunset Valley really is great. You can change a lot from private to community by clicking on it in Edit Town mode to access its options.

Changing Appearance: Perhaps obviously, you can pick a lot already in use and just change its appearance. Some families have small houses and massive gardens, and there is nothing to stop you from completely altering their land in Edit Town mode. You could, for example, create a large hill where it was previously flat, make new ponds, forests or perhaps something completely different, like a run-down derelict section of town. The possibilities are endless. Having a slum with depressed Sims living cheaply could give Sunset Valley a whole new character. Or, you could just paint someone else's house pink.
You can also edit lots such as the school and library, changing their position and appearance. Some restraints naturally must be in place to stop gamers from destroying a functioning town, but the tool is pretty powerful.
It's a very nice town.
