About This Home
As of January 2026Completed in 2021, this contemporary estate pairs modern architecture with traditional reclaimed brick all in a soft white palette. Just over one acre of level grounds with two gated entrances frames the two-story home, which has 5 bedrooms, an office, and 5.5 baths, including an optional ADU with laundry and kitchenette ideal for an au pair or extended family. Beyond the formal venues, a main kitchen and professional chefs kitchen serve an open family room where disappearing glass doors create a seamless connection to the outdoors on two sides of the room. Four additional bedrooms are located upstairs, including the primary suite with sitting room and couture closet. The grounds are designed for entertaining with a pool, spa, and open-air cabana with full bath all in a secluded, beautifully landscaped setting.
