Custom Home Builders in London, ON

Homeowners weighing 47 custom home builders in London, Ontario face a market where building a house and buying a house in a planned neighbourhood are two very different paths. Several firms here do both, so a homeowner with a lot and a buyer choosing from model homes will meet many of the same names.

Plenty of London builders sell homes in communities they develop. Millstone Homes of London, rated 4.3 from 95 reviews, builds luxury custom homes in London and Southwestern Ontario and sells new homes in planned communities including Edgewater Phase B, Goldfield, Olive Tree Gardens and Talbotville Meadows. Halcyon Homes, rated 4.4 from 13 reviews, develops Talbotville Meadows, North Forest Village and The Heathwoods at Lambeth. Legacy Homes, rated 4.8 from 6 reviews, builds in Riverbend Towns, Timberwalk, Sunningdale Crossing, Warbler Woods and Fountain West Towns. Marquis Developments, with an Arva address and rated 4.3 from 11 reviews, develops Sunningdale Court Phase II with executive sized lots.

For owners who already hold land, a different group fits. Crown Homes of London, rated 4.8 from 24 reviews, builds on its own lots or on land the client owns, and its infill service covers a client's property in an established neighbourhood or on private acreage, from demolition of existing structures to utility hook-ups and house placement. Evergreen Design + Build, rated 5.0 from 35 reviews, builds on a vacant lot, a teardown or a forever home plan. Copp Backyard Homes builds on the client's lot with a modular approach, and XO Homes, based in Arva and rated 5.0 from 11 reviews, builds on client-owned lots and helps evaluate land.

The shared page runs a little beyond the city. Arva and Thorndale are the two smaller towns whose businesses sit here. Precision Homes London Inc. and Dick Masse Homes Trails at Wye Creek are both based in Thorndale, and PI Homes builds in London and nearby towns such as Talbotville and Ailsa Craig, using ICF walls. Bridlewood Homes has built in London and Sarnia since 1991 and lists available lots on neighbourhood pages for both. The wider reach is toward Sarnia, Aylmer, Grand Bend and Forest.
