Wescon: Premier Home Builder in Westford, MA

Company president Dave Guthrie founded Wescon in Westford, Massachusetts in 1994. A Westford native, Dave was committed to responsible development and quality construction in his growing home town. He launched the company by building single family homes in Westford, but quickly expanded services to include the construction of luxury custom homes and select, stick built commercial buildings in Westford and surrounding towns including Chelmsford, Townsend, Carlisle, Tyngsboro, Littleton and Concord.

In 2001, Wescon joined with Guthall, a partnership between Dave Guthrie and local real estate attorney Howard Hall, to build The Village at Stone Ridge, an age-restricted condominium community on 108 acres in Westford. The success of The Village at Stone Ridge made Wescon a leading builder in Massachusetts. Wescon partnered with Howard Hall again to develop Summer Village at the Pond, a waterfront community of 276 seasonal cottages and resort amenities in Westford.

In 2014, Wescon joined forces with Jamesco Development to create Archstone Builders. Archstone Builders combines the strengths of each company to offer premier residential development and home building services throughout Massachusetts’ Merrimack Valley.
