Pre-made floor plans?

I'm far too lazy to build my own entire houses, but I really wish I could see the floor plan of a house before I move my Sims in. The description of beds/baths can be misleading and is it 3 BR with a huge living room or 5 BR and each room is really tiny or what… I've done a Google and I searched here as well, but I haven't found a site that shows the prebuilt lots and I was wondering if such a thing exists. Thnx!!
