Hi, I'm looking for a movie I saw a long time ago, perhaps a 70s horror movie. There was a "smart house" and a girl gets stuck in the house and the temperature starts to rise. It gets really hot and she has to lay on a table because she can't touch the floor. At one point, she sees someone (the architect?) outside but can't go because she can't touch the floor. Can someone please help me find this movie?
Thank you!

Demon Seed (1977) (http://www.imdb.com/title/tt0075931/reference)

Quinn that is exactly what I was thinking, except being impregnated by the house sticks strongly in my mind.
