Home Additions

Add square footage that looks original to the house — dormers, second stories, sunrooms, and more.

Starting at $120,000Typical timeline 12–28 weeks

Our approach

Home additions add the square footage a growing family needs without forcing a move. Dormers, second stories, sunrooms, and rear additions — we specialize in making new construction look original to the existing house, right down to the trim profiles and roofline.

The first question we answer: can the existing foundation and framing support what you're adding? Our structural engineer reviews before you sign anything. For second stories we shore and reframe from below; for ground-level additions we match footing depths and siding to existing. Matching brick, stone, or stucco to a 1920s Chicago home takes legwork, and we budget for it explicitly.

What's included

  • Structural feasibility study

    Confirms the existing structure supports the addition before contracts are signed.

  • Permit and zoning review

    We handle variances, setback reviews, and all City of Chicago approvals.

  • Match-to-existing exteriors

    Brick, stone, stucco, siding, roofing, and trim sourced to match the original house.

  • Weatherproofing

    Every new wall and roof meets Illinois energy code with continuous insulation and air sealing.
