Breakwater House

"KTA was exceptional to work with from start to finish. They asked the right questions, paid attention to detail, and listened to our needs. KTA did an excellent job partnering with the builder, and developed creative solutions to keep the project on budget while maintaining the integrity of the design and energy efficiency. They are very progressive in using technology to collaborate and communicate effectively. We love our new home and it truly exceeds our expectations."


Our clients were “from away,” but they were in love with everything Maine has to offer. They wanted to create an in-town office and home suitable for extended vacations to Maine’s coastal Rockland area, with two separate offices and opportunities to enjoy the views and sun from as many angles as possible. They also wanted to create a low energy or net-zero energy home that would be affordable to build and save them money over the years they’d spend there.


We focused on the panoramic views of Rockland’s working waterfront and historic breakwater lighthouse, aligning the footprint to capture views to the east and winter sun from the south. The compact home respects the neighborhood’s established pattern of small properties in close proximity, offering the owners contemporary amenities that still fit into the street pattern.

The home has no basement, and fits guest rooms, storage, and services on the first floor. The second floor includes open plan living spaces that allow them to entertain guests, and there’s a workspace and bedroom on the top floor.

Exterior doors and decks facing east frame views of the Rockland Breakwater and Penobscot Bay. Large south-facing windows capture winter sun, and can be protected from summer sun by exterior slats. A carport structure doubles as a large second floor deck, and a balcony suspended from the third floor has a Crow’s Nest perch for two with a 270-degree view.
