02 · Renovation

Welch House, as it stands

Welch House closed in April 2026 and is under renovation. The design starts from the building as it is: listing photography from the spring, and the existing-conditions drawings the workshop set is built on.

Welch House

The direction from the 29 September workshop: an amenity-led flagship for the Boothbay Harbor collection, used year-round. The McKown Street front stays close to its historic character; the rear is modernised to open to the harbor, with double-height public rooms, expanded decks and a mix of suites, some with private decks.
