584 Milltown Rd Brewster, NY 10509

Set on five private, wooded acres in one of Putnam County’s most desirable locations, this exceptional 21-room estate offers rare privacy, scale, and architectural significance. Originally built in 1928 and featured in House Beautiful, the home was designed by Ilonka Karasz, renowned artist and co-founder of MoMA. After serving as a wellness retreat, the property has been thoughtfully restored to a stunning single-family residence. A grand foyer opens to a dramatic vaulted living area anchored by a striking fireplace and sliding doors to a garden terrace. The dining area flows seamlessly into a sunlit wet bar and a newly renovated, lofted chef’s kitchen with high-end stainless steel appliances, oversized windows, and a statement granite island. A winding hallway leads to ten renovated bedrooms, five with en-suite baths. A lofted library with a fireplace connects the bedroom wings, while an additional living room or study opens through Andersen doors to a private rear terrace. A winding staircase leads to a beautifully renovated studio with panoramic views and its own terrace. Additional spaces include a billiards and poker room, fitness center, wine cellar, and attached two-car garage. Outdoor amenities feature a 35-foot swimming pool, a tranquil pond, and a covered carport creating a true estate setting with exceptional versatility. With its scale, layout, and prior use, the property offers outstanding flexibility for a variety of lifestyle or income-producing opportunities, including a boutique bed-and-breakfast, luxury short-term rental, wellness or retreat center, private event venue, or multigenerational compound, subject to approvals.
