In New England, it’s an honor to work on a listed, antique home. Right behind that highest of honors for the Yankee carpenter is the opportunity to put an addition onto a replica of a famous antique home, the Jethro Coffin house of Nantucket, circa 1686.

With this addition, the client asked us to design a structure that would work as a large, front porch addition—easy enough—but also one that could readily adapt itself to becoming a conditioned space in the future.

On this project we designed the structure, working closely with the client, produced all the necessary construction drawings, sourced the native timber, the custom tongue-and-groove roof decking, and all the specialty hardware; we performed the exacting demolition of the old siding so that no new siding would need to be patched in, cut and erected the frame, and installed the standing seam metal roof.
