Context

A family chose to move from their spacious, wooded Cumberland surroundings into the city to reduce the time spent in their cars and to integrate more into the urban fabric. They wanted open, family living but were challenged with one of the few remaining in-town Portland lots, very narrow with setback limits from all sides and with regulatory design constraints. Ideally the house would attain net zero energy and would be tall enough to get views of Casco Bay.

Response

A new structure reaches four stories in height to attain views over many adjacent rooftops and to 270-degee views of the water and the islands beyond from a skyroom and deck. Contemporary forms interlock to create a main living volume that seems to float above the recessed parking below, and a top-floor shifted box clad in wood. Large windows capture the light and lower-level views, and smaller openings regulate privacy. The house is super-insulated and has 12kW of PV to reach net zero energy and provide charging for an electric vehicle.

In Town

The house is less than two blocks from the park, with beach and water access, and walkable to downtown Portland and its many amenities. Public transportation is steps away.

Renewable Materials

All materials that have been used throughout are low- or no-VOC. The acetylated wood used on the exterior of the home is manufactured via a non-toxic treatment and uses fast-growing softwood timber from sustainable sources. The result is a highly durable, but natural rot-resistant material.

Water Conservation

All fixtures are low-flow and low-volume.

Energy Efficient

This building is capable of achieving net zero energy, including a superinsulated, extremely airtight shell and high-performance, triple-glazed ventilating windows.

The house will incorporate heat pump technology in the heating and cooling, water heater, and dryer. It is also designed to maximize the use of natural light to save energy, requiring very little use of electrical lighting throughout the day.

Renewable Power

The house will provide all of its own energy on site through 12kW of PV.
