Home Addition Services in Chicago

Room Additions

Need a new bedroom, home office, or family room? We frame, insulate, drywall, and finish new room additions from the ground up, fully permitted and code-compliant.

Bump-Out Additions

Expand your kitchen, dining area, or living room with a professionally engineered bump-out that blends seamlessly with your existing structure.

Second Story Additions

Double your living space without losing your yard. Our structural team handles foundation assessment, framing, roofline integration, and interior finish.

Kitchen Expansions

A larger, more functional kitchen starts with the right addition. We coordinate plumbing, electrical, cabinetry, and finish work under one roof.

Transform an underused garage into livable square footage. We handle insulation, HVAC tie-in, flooring, and all city permit requirements in Chicago.

Sunroom & Porch Additions

Bring the outdoors in with a four-season sunroom or enclosed porch addition built to withstand Chicago winters and maximize natural light year-round.
