Unless there’s a continuous scene where you watch characters move from one room to the other with no cuts in between, you’re more than likely seeing several different locations stitched together to appear as though they’re the same place. This especially happens when filming in and outside of a house- it’s rare you’ll find a location that fulfills ALL your needs, and it’s rarer still that an interior will have an exterior that you also like. Example: if you’re from a desert area but your film is set in a snowy area, you can film the interiors locally and then pretend that the exterior of a different house in a snowy area is the outside.
Make a list of the particular rooms you need and any shots that would require you to be in the same location (for instance, if you have a scene of a person standing in a hallway of a house with two bedroom doors and thus you need a location with two doors off of a hallway, even if you film the rooms themselves elsewhere). Then ask your collaborators for access to those individual elements instead of the whole list, and after you’ve created your house out of these elements, get a production designer to help you match all these different rooms so they seem like they’re part of the same house.
Never underestimate the power of faking it
