We ahve just signed a contract for building a modular home, we had planned on putting a 2 car garage in the basement with the doors facing toward the street, we do not have enought room on the sides of the house to make a driveway. The way the blueprints are written, they have some columns 6 1/2 ft apart, while some are 8 1/2 ft. apart. This presents a problem with our garage (the reason why we sold our old home and bought this modular was because we wanted a BIG garage!) How far apart can these beams be safely placed? It is a 26' 8" by 60' home. It has a microlame beam built into the house. Please tell me at least the width of a garage door!!!!
