The project was designed by Dennis Mires, PA, The Architects.

Milestone relocated the historic Folsum Tavern three hundred feet to its current Water Street location. George Washington entertained dignitaries at the tavern on one of his visits to New Hampshire.

The Lethbridge Lodge at Colby Sawyer College is a new facility that brings out the history of Colby Sawyer College. The sitting room pictured is framed with the beams and sheathing dating back to the original New London Town Hall. That building was eventually dismantled and the materials were used to construct the Colby Town Camp on Little Sunapee Lake in New London, New Hampshire. Milestone dismantled the Colby Town Camp and labeled each and every piece for incorporation into the new Student Lodge. This historic, authentic old wood frame was restored and incorporated into a new facility consisting of a sitting room, kitchen, bathroom, and recreation facilities for the students.

The Cleveland Colby Colgate Archives is a complete restoration of what was once a barn on the site of the original farm. The barn attached to the original homestead and the Susan Colgate Cleveland Library were in such despair that they were literally collapsing. Milestone shored and preserved the original frame while constructing all new foundations and slabs and performed a complete restoration of the entire facility.
