New construction, this extraordinary custom Cape Dutch residence is a masterwork of timeless design, brought to life by Duncan and Heuser Design and Development, with interiors curated by James Duncan. Every detail, from the graceful gabled facade to the refined finishes within, reflects a rare devotion to craftsmanship and
enduring elegance. Offering six generously proportioned bedrooms and six and a half beautifully appointed bathrooms, this home balances gracious scale with warm, livable comfort. Soaring ceilings, thoughtfully placed windows, and an effortless flow between rooms create a sense of light and openness throughout, while curated materials and bespoke millwork lend a distinctly luxurious character to every space. This is more than a house; it is a legacy residence, designed to be lived in beautifully for generations. A truly rare offering for the discerning buyer seeking timeless architecture, exceptional interiors, and uncompromising quality throughout.
