| Scope | Typical Range | What's Included |
|---|---|---|
| Single-Room Addition | $150,000–$225,000 | Primary suite, sunroom, or home office addition. New foundation, framing, roofline tie-in, HVAC extension, full finish. |
| Kitchen Expansion or Great Room | $200,000–$300,000 | Structural addition connecting to existing kitchen or living area. Load-bearing changes, matching exterior, full interior finish. |
| Full Wing or Multi-Room Addition | $300,000–$400,000+ | Two or more connected rooms with new roofline, foundation, mechanical systems, and premium finishes throughout. |
Every addition requires new foundation work and framing that ties into the existing structure. This is the largest single cost driver and is non-negotiable for structural integrity.
Matching the new roofline to the existing home without visible seams or transitions requires skilled carpentry. Poorly executed rooflines are the most common addition failure point.
HVAC, plumbing, and electrical must be extended from the existing home into the new addition. Depending on your current system capacity, upgrades may be required.
Siding, windows, and exterior trim must match the existing home exactly. Mismatched materials are visible from the street and reduce resale value.
“Home additions are the most complex projects we take on — and the most rewarding. Done right, they add real square footage and real value. Done wrong, they’re a source of regret for years. We do them right.”— Adam Kilgore, AK Renovations
Yes — a single-room addition of 300–400 square feet (primary suite, sunroom, or home office) is achievable at that range with quality finishes. Anything involving multiple rooms or premium exterior materials starts at $200,000+.
Adding square footage increases your assessed value, which increases taxes. The amount varies by Summit County township. Your county auditor can estimate the impact before you build.
Usually yes, though there will be days with significant disruption — especially during foundation and framing. We plan the sequence to minimize the number of days you can’t use key areas.
Most additions run 3 to 5 months from permit approval through final punch list. Design and planning typically adds 4 to 8 weeks before permits are submitted.
Landscaping restoration, driveway repairs, and interior furnishings are not included. Everything else — materials, labor, permits, trades, and project management — is.
