A house in the UK will have a ceiling somewhere between 7ft and 9ft high, unless you smash holes in from the room above, you can’t get a high angle. Building a set allows you to shoot from any angle, even below.
A normal house is lit by small windows, so natural light is limited, depending on the shot but not as limited as the number of amps you can pull from a domestic ring main for your lights. Building a set gives you access to much more power and you need fewer (if larger) lights.
A medium sized property generally has only one parking space if any, and the crew can rarely turn up on the tube. Studios have car parks, loading doors and can hold the kit overnight.
You can hire a location for a lot of money, a little money, or even for free but you still can’t paint it any colour you want and move a wall that blocks the action.
Building a set lets you float walls and ceilings around all you want.
If you are building a set, you can make a space that fits your lens and tells your story. You will, already have begun to take the audience where you want them.
Reality, is not why we work in movies, we are creating a better reality, so create it, don’t borrow one thats wrong!
