The Cleaver House:
Was on a Universal Studios backlot street called Colonial Street. It replaced another house at Republic Studios, where
Leave it to Beaver was filmed for the first two seasons. It is now moved to an out-of-the-way part of Universal's backlot.
The Cleaver House wasn't actually built for the show; it was built for the 1955 Humphrey Bogart movie
Desperate Hours. That movie was filmed by Paramount, on backlot space it rented from Universal, so the house was referred to as the Paramount House for a while. When Universal began using it for
Leave it to Beaver, it was altered slightly and was given "matching" features to make the exterior correspond with the interior sets, which were on a soundstage elsewhere at Universal. This was primarily done with adding draperies to the windows that matched those on the sets.
The house has been moved several times, and was substantially altered at one point to become the home/office of Marcus Welby, M.D. It was restored for the early-'80s
Still the Beaver TV-movie, but has since fallen into disrepair again and has been replaced with a newer copy built for the
Leave it to Beaver movie. That one is the Cleaver House currently seen on Universal's tours, not the original.
What is interesting about these movie houses is that they are usually built in 3/4 scale, not full-size; only the lower storey's windows and doors are the size you would expect. For some strange reason known only to Hollywood set designers, structures built this way photograph as being normal-size, yet cost less to build.
Also, most sitcom houses serve a dual purpose - since there is not really anything inside them (except lights behind windows for night shots), their facades typically conceal storage for studio equipment like lights and electrical stuff. Real estate in L.A. is too valuable to waste an inch of space.
Sad that this house isn't getting more care, and even sadder that Universal tour guests think they're looking at the original when they're not.
Here's a pic from 1962 or so, when the house was seen on the show. Note the East Coast-style landscaping, which cost a fortune to maintain in Southern California. When a show stops using a movie house, the landscaping is always the first thing to go:
