Buffy’s house was orignally shot on location, but was later built on a soundstage to make filming easier. Changes can be seen in the original and rebuilt house:

1. In The Witch, when Buffy walks into the kitchen, we can see that the regular dining room is not through the door. Instead, there is a hall with peach-coloured wallpaper.
2. In Never Kill a Boy on the First Date, in the scene where Giles finds Owen at Buffy’s house, it looks like there is no entrance to the dining room to the right of the front door.
3. In Angel, when Angel bursts through the back door in the kitchen after Darla has bitten Joyce, we can see that the back door is different. The exterior side is green not white, and it’s window only has 4 panes, whereas the on-set house has 9 panes. The white door with nine panes can be seen in Surprise.
4. In Angel, just after Buffy and Angel run into the house to escape The Three, Angel looks through the window at one of the vampires. At that point, the window is small and divided into four panes. It also has a white and yellow checkered curtain over it’s bottom half. In The Body, it can be seen as a longer, thinner, frosted window on either side of the door.
