FAQ — Home Additions in Lexington
Do I need a variance for an addition?
It depends on your lot and the addition's footprint. We pull setback and zoning data on the feasibility visit and tell you upfront whether you'll need a Zoning Board variance — most additions in Stoneham, Woburn, Reading, and similar towns don't need one if you stay within existing setbacks.
Can you match my existing siding?
Yes. We match clapboard, vinyl, cedar shake, and brick. For older homes with discontinued siding, we either match by color/profile or we re-side the affected wall plane to maintain visual continuity.
How much does a home addition cost?
Single-room additions in our market run $80K–$180K. Second-story additions run $180K–$320K. Master suite additions with bath run $150K–$280K. Sunrooms run $90K–$160K. Your detailed proposal in step 02 has a fixed price, not a range.
How long does construction take?
From foundation to final inspection: 3–4 months for a single-room addition, 5–7 months for a second story, 6–8 months for a complete master suite with bath. Permitting adds 4–8 weeks before we break ground.
