How Much Does a Home Addition Cost?
When you love your neighborhood but need more space, an addition beats moving – no bidding war, no new mortgage rate, no leaving the schools and streets you chose. Here is what a home addition costs in Westchester County, priced the way builders actually price them: per square foot.
Typical home addition investment: $250 to $350 per square foot
Additions are priced per square foot because size and complexity vary so widely. A simple bump-out sits near the lower end; a two-story addition with a new kitchen or primary suite, complex rooflines, and high-end finishes moves toward the top.
What Drives the Cost Per Square Foot
Design complexity is the biggest lever. A straightforward rectangular addition on an existing foundation line is efficient to build. Adding a second story, tying into complex rooflines, or matching the character of an older home takes more skilled labor. Finishes are the other lever – an addition that includes a new kitchen or bathroom carries plumbing, electrical, and cabinetry costs that a simple family-room expansion does not. Site conditions, foundation work, and how cleanly the new space ties into the existing structure all factor in.
A Simple Way to Estimate Your Project
Multiply the square footage of your planned addition by the range above. A 600 square foot addition, for example, would fall roughly between $150,000 and $210,000 depending on design and finishes. It is a starting point – the accurate number comes from a site visit where we can see your home, your lot, and exactly what the addition needs to tie into.
