This house isn't completely decked out with furniture, it just has the basics, I had to keep it under 20,000. It's a starter, so earn money and decorate it however you like.
eta - As my boyfriend pointed out, in the living room where the bookcase is, you could move it over slightly, add a door and have stairs leading down to a basement if you wanted more room in this house. I thought that's a good idea anyway, something I'll most likely do when I move a sim into this house.
Some people may have been having problems installing this house. I've uploaded a new version which has been decrapified and s3rc'd and it now works.
