We have an older kit and I ordered it as an "expansion" of sorts to give more building options. The door is essentially the same, but they redesigned the window (probably to save on plastic, which is a plus). Well. The new roof style absolutely sucks. It consists of plastic trusses and individual clapboard panels. Panels are difficult for little fingers to maneuver and we lost quite a few in just a few months. We're disappointed, especially since we have an old, solid, one-piece, one-piece plastic roof to compare with. It works well as an expansion pack if you happen to have an older version.
