What Is a Bump-Out Addition?

How Can a Bump-Out Add Significant Space?

This would not be considered a major space-maker relative to the entire house.

These 45 extra square feet would only add 3% to a 1,500-square-foot home.

Bump-outs are often installed in rooms that are already very smalloften so tiny that they are barely functional.

A 150-square-foot kitchen, when bumped out another 45 square feet, receives a 30% boost in space.

Increasing the kitchen by one-third can be enough space to make the kitchen easier to work in.

Grade-level (first-floor) bump-out additions can be cantilevered or have simplefoundations.

They can rest on a concrete slab or foundation walls, which can create a crawl space.

Upper-level bump-outs, when short, are small enough that they can be cantilevered from the second-floor framing.

A bump-out addition can be as shallow as 2 feet and as deep as 15 feet.

Even the most experienced DIYers should leave a bump-out project to the professionals.
