New Rule: Custom Patterns are Not Allowed, this is simply because they do not always transfer well and can look messy once downloaded.
(Patterns made in Creat a Pattern)I think where I live it's two houses connected to each other. But that seems to be different than what Thomas intends it to be.
That's a Terrace but it could also be considered a Town House. By Town House I really mean a House you'd typically find in a Town, so it won't have a huge garden for example.
I started getting blurry here, when you say must fit the town's theme, you mean towns like sunset valley and Bridgeport, or you mean real towns?
I'm sorry it's confusing for everyone. The Town Houses must look like they fit in the centre of a town, in Sims. Which town is up to you or whether you just want to build a House you would find in a town that's fine as well.
