Residential development occurred in the postwar years in several spurts.
In the late 1940s to 1950, cottages around Long Lake off Goldsmith, on the Littleton side of Forge Pond (called Lake Mattawanakee), along Spectacle Pond, and beside Mill Pond off Harwood Ave were either winterized or torn down and replaced by bungalows and Capes.

At the same time, new construction went up along New Estate Road, Whitcomb Ave, and Tahattawan Road.
From 1955 through 1965, Snow Village (off Great Road about a quarter mile before Power Road—formerly Snake Hill Road), Edsel Road (Kimball land behind the current Post Office running up the hill on the right of Goldsmith Street), and lower Hartwell Ave (in the subdivision abutted by the cemetery, King St, and Hartwell Ave) were built with ranch houses and larger Capes.

In the late 60s and early 1970s, stretches along Harvard Road, Taylor Street, Liberty Square, Foster Street, Mill Road, and Grist Mill Road saw some of the first split-levels and five-bedroom Colonials go up.

In the late 1970s and early 1980s, the farms between Hartwell Ave and Great Road were developed along with upper Hartwell Ave.
In this period, the livery stable at the corner of Coughlin Road and Newtown Road sold off more than half of its land to developers.

In the late 1980s and early 1990s, the horse farms along Russell Street off Great Road closed and were developed as well as some of the horse farms off Harwood by the quarantine station.

The start of the 21st century has seen further building of quite large Colonials along Great Road, on Fort Pond Hill, and along Beaver Brook Road.
