This 1826 Beacon Hill single-family townhouse received upgrades that were seamlessly integrated into the existing reproduction Georgian-period interior. Also, a new contemporary kitchen with a feature ceiling exposing the existing rough-hewn timbers of the floor above, and custom-sawn black walnut flooring. Circulation for the new master suite was created by a rotunda element, incorporating arched openings through curving walls to access the different program areas. The client's antique Chinese screen panels were incorporated into new custom closet casework doors, and all new partitions and casework were blended expertly into the existing wainscot and moldings. Architecture: Frank McGuire Architects, with Stack + Co.
