Copper House

Copper House in Boston, Massachusetts, is an architectural intervention by Kennard Architects to an 1895 Neo-Classical residence. The project's brief called for modern living spaces and enhanced functionality while respecting the historic character of the original home, situated on a steeply sloping site. A series of copper-clad additions are positioned in response to both the existing architecture and the site’s topography. These contemporary volumes introduce new spaces, including a kitchen, family room, master suite, and sunroom to the main house, while a reworked detached carriage house accommodates guest quarters and a gallery. Interior spaces are organized with interlinking stairways and half-levels, providing varied views and daylight access throughout. Exterior stepped terraces make use of the slope, defined by stone and boulder retaining walls that relate to the geometries of the copper elements. Together, these components create a nuanced relationship between the historic structure and its contemporary interventions.
