Home Additions in Bedford, NY
Westchester Home Addition Service Serving Bedford
Additions that belong in Bedford Village, Bedford Hills and Katonah: designed around historic review, large-lot zoning, and wells and septic, then built under a single Guardian project manager.
Bedford Additions Start With Character
Bedford’s three hamlets each have a distinct look: the green and the colonial-era houses of Bedford Village, the turn-of-the-century streets of Katonah, and the varied neighborhoods of Bedford Hills. Out on the back roads, homes sit on large, wooded and often rocky lots, many with stone walls, outbuildings, wells and septic systems.
An addition here has to fit all of that. Rooflines, window patterns, siding and trim matter, and the town has real review processes to make sure they do. We plan for that review from the start instead of treating it as a hurdle at the end.

Bedford's Three Historic Review Paths
The Town of Bedford has three separate historic preservation commissions. Which one applies, if any, depends on where your home is:
Bedford Village Historic District
Reviews changes to exterior architectural features and landscapes within the district. A Certificate of Approval is required before you apply for a building permit.
Katonah Historic Advisory Commission
Reviews major changes to exterior appearance for properties within the Katonah historic district.
Historic Building Preservation Commission
Covers listed properties outside the districts. Tier 1 is reviewed for demolition or substantial exterior alterations, Tier 2 for demolition of over 50% of wall surface.
Designing an Addition That Passes Review and Looks Right
- Keep the original house dominant. Additions set back from the main facade, or slightly lower, generally read as respectful.
- Match the roof pitch and overhangs, and continue the existing eave and rake details.
- Use compatible materials: clapboard or shingle profiles, trim widths and window divided-light patterns that relate to the house.
- Mind the site. Stone walls, mature trees, ledge and septic fields often decide where an addition can sit.
- Plan the tie-in. We open the existing house only after the addition is dried in, to protect older interiors.
The building permit itself comes from the Town of Bedford Building Department in Bedford Hills, after historic review, zoning and any county health department approvals.
Bedford Home Additions FAQs
My house is in the Bedford Village Historic District. What changes?
Exterior changes there, including additions, are reviewed by the Bedford Village Historic District Review Commission. The town requires its Certificate of Approval before you apply for a building permit. The review covers architectural features, materials, windows, landscape and more, so we design with the district’s character in mind from the first sketch.
What about Katonah?
Properties in the Katonah Historic District go to the Katonah Historic Advisory Commission, which reviews major changes to exterior appearance. It is a separate body from the Bedford Village commission, with its own application.
My house isn't in a district but it's old. Am I affected?
Possibly. Bedford’s Historic Building Preservation Commission reviews listed properties outside the two districts. Tier 1 properties need review for demolition or substantial exterior alterations. Tier 2 properties are reviewed for demolition of more than 50% of structural or exterior wall surface, which a large addition tie-in can approach. We check the town’s list for your address.
Where are Bedford building permits issued?
The Town of Bedford Building Department is at 425 Cherry Street in Bedford Hills. Historic review, zoning and any health department approvals come first, and the building permit follows.
Will an addition affect my well or septic?
Many Bedford homes on larger lots use private wells and septic systems. New bedrooms usually mean a Westchester County Department of Health review of septic capacity, and the addition’s footprint has to respect setbacks from the septic field and well.
