Thoughtful architecture begins with listening to the landscape.

Designed to nestle within Maine’s lush coastal setting, this home uses a series of multi-level decks and expansive sliding glass doors to capture ocean views, draw in natural light, and create a seamless connection between interior spaces and the outdoors. Carefully sited among the trees, the architecture feels both sheltered and open... an intentional response to its extraordinary surroundings.

Mid-century lines and modern living.

A house that almost hovers where light leads and walls dissolve.

Through a dramatic double-height entry, a floating staircase sets the tone, and walls of glass pull the outdoors in from every angle in this home. As Sarah Jefferys puts it, it’s that quiet tension between simplicity and impact that makes the space come alive... where nature, light, and architecture move as one.
