As others have written, it makes no sense to criticize Mark Bennett for his drafting prowess or lack thereof. He draws blueprints as well as can be hoped for for an amateur draftsman. That is, he draws better than most of us can hope to do. Even Franz Joseph Schnaubelt, who was a professional, had numerous inaccuracies in his historic "Booklet of General Plans" (a.k.a. Star Trek U.S.S. Enterprise blueprints). There's only so much you can do with fantasy plans. Aside from the sets changing often, people have to remember that these were never real houses. They were sets. As such, they often had extremely unrealistic interiors that would never have fit together inside a real house. I think he did a very good job on one of my favorite homes, the Brady house featured on the cover. (You know; the house that looked like a single-story ranch from the outside yet had a second floor and an attic. Prime example of why fantasy houses can't be drawn precisely.)

That said, some of his blueprints do have significant errors. The Jupiter 2 from "Lost in Space" seems completely wrong. Many rooms and items are on the wrong level altogether. The Jetsons' home is also much too small, taking up an entire floor of what should be a large apartment complex in the sky. Ditto for Gilligan's Island, which he makes about the size of a city block. On this island, the castaways would never have gotten lost, as they often did, nor could strangers have hidden, again as they often did. Also ignored was the first season set for the Odd Couple, which was copied from the movie set. Instead, Bennett describes the season 2 through 5 set as the only apartment. Disappointingly, some very familiar but non-residential sets were not covered. How about the Batcave and Wayne Manor? The newsroom from Kolchak: The Night Stalker? Barney Miller's squad room? Then there's also the Three's Company apartment. Major Nelson's house from "I Dream of Jeannie," both the original and the season 5 renovation. Anyone up for Volume 2? Somebody get that man some DVDs. Stat!
