About the Home

This Westport residence is a meticulously executed Passive House retrofit of a modernist concrete home originally built in 1938. Few properties achieve this level of energy efficiency while also prioritizing non-toxic, health-conscious building materials. As you pass through the home's front entry gate and hear the gentle rhythm of tires over gravel, a striking and handsome facade comes into view-an arrival that feels both intentional and memorable. The setting immediately conveys a sense of privacy, character, and architectural distinction. Your attention is naturally drawn to one of the most distinctive features of property: the Frazier Peters outbuilding. Rich in charm and architectural interest, this versatile structure offers exceptional flexibility-equally suited as a private office, creative studio, retreat, or state-of-the-art gaming lounge. The space adapts effortlessly to your vision and lifestyle Originally designed by Frank Lloyd Wright protege Francis Barry Byrne, the home is a masterwork of form, function, and sustainability. Proportioned according to the Golden Ratio and set high atop a hill, those who visit cannot help but to enjoy sweeping views of mature rhododendrons and stately oaks. Inside, limestone walls, clean architectural lines, and abundant natural light create an atmosphere that feels both striking and serene.
