I have a commercial paint booth at work, but its small, works great.
Have painted a few cars at home in my garage, use a fan that pulls the air out of the makeshift booth not pressurises it. Dust fume extractors are pretty good as the motor sits outside the fan assembly
Clear drop sheets attached to the walls roof etc, wash down the floor bring the car in and paint away. I made a dummy entrance door that was my filter pack.
Have also painted a car in my mates back yard, amazing how much dust and dirt is in the air
