It's called billy's shed, and it has some nice cut-out buildings. All you have to do is print them off on card-stock, or glue the paper to cardboard, then fold and glue! If you take enough time with them, and do a few embelishments, they will turn out very nice.
As for hills:
Cut out two oval of circular sections of styrofoam. Be sure that the smaller piece will sit on top of the larger with enough room left for the minitures to stand on the bottem row. Glue them together (glue-gun hot glue works best.)
Next, cut or crunch the edges where you cut into a slight slope so your hill does not look "boxey."
Paint green.
While paint is still wet, sprinkle on some grass-flocking or green saw-dust. Allow to dry, then shake off the excess.
BAM! A nice little hill.
But! I have seen lot's of people use books, and then throw over a section of green felt. Add some trees and stuff, and it does not look bad.
Almost forgot, the buildings at Billy's Shed are free for download. Also has some links for other free cut-out buildings, and pay-sites.
