A Remarkable Roof with a Story to Tell

Distinctive and rich in architectural character, this turn-of-the-century Colonial is a special Port Washington treasure. Documented on a 1914 map, the home offers a fascinating connection to the community’s past while retaining the warmth and charm of a gracious residence.

The home’s architectural details make a memorable impression. A distinctive front gable, rising above the main entrance and featuring four square second-floor windows, enhances its classic Colonial appeal. Below, a contrasting white front porch, framed by impressive columns and accented by elegant overhanging cornices, creates a striking and welcoming entrance. The stained-wood front door, accented by a beveled-glass panel, adds warmth and character.

The home’s most remarkable feature is its unusual green copper roof, a distinctive architectural element that sets this property apart. Historically prized for its beauty, durability, and longevity, copper has long been valued as a premium roofing material. Over time, exposure to the elements transforms the metal, creating the beautiful green patina that gives this roof its distinctive appearance. Whether original to the home or installed at a later date, it lends an unmistakable sense of individuality and timeless elegance.

Set on an oversized lot adorned with beautiful mature plantings, the property offers a lovely garden-like setting that complements its classic architecture. Established greenery enhances the home’s appeal, creating a sense of privacy and a welcoming connection to the outdoors.

With its distinctive copper roof, impressive columned porch, traditional architectural details, and beautifully planted grounds, this special Colonial captures the enduring charm of Port Washington. It is a home with a story to tell, offering a rare combination of architectural beauty, individuality, and old-world character.
