A bathroom addition can be a bit more affordable, with the average project expenses ranging between $10,000 and $25,000 including materials and labor.

If you want to add a bigger space to your home, such as a large living area with a vaulted ceiling, you can expect expenses to climb as high as $100,000. You’re likely going to need a stronger foundation, a more sturdy roof, and more materials for interior outfitting.
