Spent the last couple of evenings creating a house based on one I grew up in, in the Detroit suburb of Oak Park, Michigan.
It has a few store items (washer and dryer), and I created it in Barnacle Bay, so it has the nautical-themed mailbox.
Oak Park.Sims3PackIt has four bedrooms and a bathroom upstairs. The house I lived in didn't have a bathroom on the main floor (rather, a closet), but I took a few liberties and added one. I was also going by memory, as I hadn't lived in the house since 1983.
There's also a decent-sized utility area in the basement, as well as a couple more rooms and a bathroom. If you have Party Animal Sims, I'm sure they'd appreciate having more rooms for fun stuff.
There's a kitchen with a kitchenette, as well as a dining room, in which I put a professional bar.
Bear with me here, Photobucket's giving me crap and I'm new to Flickr. I'll be getting pictures of the interior up ASAP.

EDIT: I updated the download link. I found a small issue with the house, fixed it, and re-uploaded.
