Home Remodeling & Custom Building in Lexington, MA
Thoughtful Craftsmanship for One of New England’s Most Architecturally Distinctive Towns
Lexington is two towns in one. There’s the Lexington of the Revolution, with colonial homes along the Battle Green and antique structures that have stood since the 1700s. And there’s the Lexington of the mid-century, with the country’s most concentrated collection of modernist residential architecture: Six Moon Hill, Five Fields, Peacock Farm, Turning Mill, Pleasant Brook, and the hillside studios of architects trained at Harvard and MIT who reimagined how American families could live.
Remodeling in Lexington means respecting both traditions. An antique colonial needs period-sensitive restoration and careful systems upgrades. A Peacock Farm or Techbuilt home needs contemporary improvements that honor the original architects’ intent. A 1990s colonial or a Colonial Revival needs thoughtful updating that improves livability without erasing the home’s identity.
Since 1992, Platt Builders has helped homeowners across Massachusetts renovate, expand, and reimagine their homes. As an employee-owned cooperative, every member of our team has a stake in the quality of your project. We listen carefully, plan thoroughly, and build with the craftsmanship Lexington homes deserve.

The Home Styles and Remodeling Challenges We See Most in Lexington
Lexington’s housing stock is unusually diverse for a town its size. Four centuries of American residential architecture are represented here, often within a single neighborhood, and each era brings its own remodeling considerations.
The earliest homes date to the 1700s and 1800s: center-chimney colonials, Federal-era farmhouses, and a handful of surviving First Period structures. Many are listed on the National Register of Historic Places or included in Lexington’s Comprehensive Cultural Resources Inventory. Working on these homes requires specialized knowledge: period-appropriate restoration, discrete systems upgrades, and careful coordination with the Historical Commission when changes trigger demolition delay review.
The Victorian and early 20th-century periods brought Colonial Revival, Craftsman, Shingle-style, and American Foursquare homes throughout Lexington’s older neighborhoods. These homes have strong architectural character, generous proportions, and often compact kitchens and closed-off floor plans that today’s families want opened up.
Then came Lexington’s second revolution: the mid-century modern wave. Beginning with architect Hugh Stubbins’s own home on Dover Lane in 1946, and accelerating through the TAC-designed Six Moon Hill (1947) and Five Fields (1951), the Peacock Farm neighborhood (1952) by Walter Pierce and Danforth Compton, and Carl Koch’s prefabricated Techbuilt houses at Middle Ridge and Turning Mill, Lexington became the most significant center of mid-century modernist residential architecture in the region. Pleasant Brook, Shaker Glen, The Grove, and other Peacock-style developments followed. These homes have devoted owners and specific renovation needs: replacing original single-pane glass, reworking flat-roof assemblies for New England winters, updating kitchens and bathrooms without compromising the architectural intent, and carefully expanding homes that were originally designed for modest footprints.
Postwar and 1960s to 1980s development brought ranches, split-levels, garrison colonials, and the first wave of subdivision building to parts of East Lexington and outlying neighborhoods. These homes are structurally sound but now carry 40- to 60-year-old kitchens, bathrooms, and systems.
The 1990s and 2000s brought larger colonials, Colonial Revivals, and Shingle-style homes on the town’s remaining buildable lots. Structurally solid, often spacious, but many now ready for kitchen, bath, and whole-home updates that reflect evolving tastes and how families use their homes today.
And scattered throughout are contemporary custom homes, some newly built, some Acorn-Deck homes from the 1980s and 1990s, and a continuing stream of teardown-and-rebuild projects on lots where the original house no longer served its owners.

Lexington Permitting, Demolition Delay, and Historic District Expertise
Few Massachusetts towns have a more layered preservation framework than Lexington. Depending on your property, you may be working within one, two, or even three review layers in addition to standard building permits.
Lexington’s Demolition Delay Bylaw applies to any building listed on the National Register, included in the Town’s Comprehensive Cultural Resources Inventory, or otherwise determined by the Historical Commission to be historically or architecturally significant. For qualifying buildings, demolition is delayed by 21 months, reduced to 12 months with an approved site plan review, to allow time for preservation alternatives. “Demolition” includes substantial removal of a building or significant portions of it, which means major renovations can trigger review even when the home is not being fully torn down.
Four local historic districts, administered by the Historic Districts Commission, require formal approval for all exterior changes including additions, construction, demolition, renovations, color changes, and signs. These districts have exclusive jurisdiction over properties within their boundaries.
Lexington also has Neighborhood Conservation Districts with their own commissions and review procedures, creating a third potential layer of review for properties within those boundaries.
Beyond preservation review, standard building permits for structural work, electrical, plumbing, mechanical, and site work run through Lexington’s Building Department under the Department of Land Use, Housing, and Development.
We understand Lexington’s review process. We identify which layers apply to your property early in the planning phase, coordinate applications and hearings, and build in realistic timelines so permitting doesn’t derail your project.

Frequently Asked Questions: Lexington, MA Remodeling
Q: Does Lexington have a demolition delay for my home?
A: Lexington’s Demolition Delay Bylaw applies to buildings listed on the National Register, included in the Town’s Cultural Resources Inventory, or determined by the Historical Commission to be significant. The delay is 21 months, reduced to 12 months with approved site plan review. Importantly, “demolition” can include substantial removal during major renovations, not just full teardowns. We confirm whether the bylaw applies early in the planning process.
Q: Is my home in a Lexington historic district?
A: Lexington has four local historic districts administered by the Historic Districts Commission, plus Neighborhood Conservation Districts with their own review procedures. We identify which review layers apply to your property during our initial site visit.
Q: Can you work on mid-century modern homes?
A: Yes. Lexington’s mid-century modern homes, including Peacock Farm, Six Moon Hill, Five Fields, Turning Mill, and Pleasant Brook properties, have specific renovation needs: replacing original single-pane glass, updating flat-roof assemblies, modernizing kitchens and baths without compromising architectural intent. We approach these projects with the same care we bring to antique colonial restorations.
Q: Can you renovate an antique Lexington home?
A: Yes. Our Concord and broader Boston-suburb portfolio includes extensive work on antique and period homes. Projects like Anti-Aging in an Antique demonstrate our approach to respectful modernization of historic structures. We coordinate all required Historical Commission review.
Q: How long does a whole-house renovation take in Lexington?
A: Most large renovations take 4 to 8 months of construction. Historical Commission review, historic district approvals, and any demolition delay considerations can add significant time to the front end, which is why we begin those steps as early as possible.
Q: Can you build a new home on my Lexington lot?
A: Yes, including teardown-and-rebuild projects. If the existing home triggers the demolition delay bylaw, we factor that into the project timeline and help you navigate the review process.
Q: Are you based in Lexington?
A: Our headquarters and cabinet shop are in Ayer, about 30 minutes away via Route 2. Our project managers are on-site throughout every active Lexington project.
