I have created a new home so you can keep all of your sims together on the same lot, throughout their lives.
You can find it at The Exchange here
or type in under lot as a search "sweet success, by jak"
Here are some screenshots:

Well, this gives you an idea so you can see all the room that one has in this home.
Thanks, hope you enjoy it.
