Welcome to 39 Running Brook Lane, an exceptional custom-built home set on 2.7 acres, where timeless elegance meets everyday function. Spanning more than 7,000 square feet across three finished levels, the residence offers both scale and sophistication. Inside, freshly painted interiors highlight soaring ceilings and generously proportioned rooms. The high-end kitchen by Dean is a chef's dream, complete with butler's pantry, top-of-the-line appliances, and a walk-in pantry. A sunlit circular breakfast nook flows into a cozy family room with a fireplace (one of three throughout the home). Formal living and dining rooms open to bluestone patios for seamless indoor-outdoor entertaining. A wood-paneled study, two powder rooms, laundry room, and a flexible office or first-floor bedroom complete the main level. Up the grand staircase, the oversized primary suite is a true sanctuary with dual bathrooms and three custom walk-in closets. Four additional bedrooms and three full bathrooms provide comfort and space for family or guests. The walk-out lower level impresses with a brand-new sauna and Himalayan salt room, alongside expansive areas for a gym, playroom, or media lounge. Privately tucked on a quiet cul-de-sac just minutes from Metro-North and downtown New Canaan, this home offers a rare combination of luxury, convenience, and comfort.
