Some properties simply cannot be replicated, and 90 Quaker Avenue is one of them. Set on 1.9 beautifully landscaped acres, this remarkable circa-1780 residence offers approximately 4,100 square feet of living space, where centuries-old craftsmanship, distinctive architectural details, and modern conveniences come together in a truly special setting. Inside, the home is defined by its character and individuality. Five fireplaces, beautifully restored wide-plank hardwood floors, and a striking two-story entry with a sweeping staircase provide a sense of history at every turn. Generously proportioned living spaces offer plenty of room to gather, entertain, or find a quiet corner of your own. The updated kitchen was finished in 2020 and is complete with a wood-burning stove, butcher-block island, granite counters, stainless steel appliances, and a walk-in-style pantry with convenient outdoor access. A dedicated office, mudroom, and additional gathering spaces round out the first floor. The second level offers four bedrooms, including an expansive primary retreat with its own sitting room, two full bathrooms, and a flexible bonus room. Two separate staircases add to the home's distinctive layout and charm. Beyond the house, the grounds are equally impressive. Enjoy summer days by the in-ground pool, a match on the private tennis court, or fresh produce from the organic vegetable garden. Established perennial gardens and mature trees create a beautiful backdrop, while the patio and pergola provide inviting spaces for outdoor dining and entertaining. A rainwater collection cistern adds a thoughtful sustainable feature to the property. Recent improvements include a new boiler and hot water heater (March 2026). Additional amenities include a spacious walk-up attic and unfinished walk-out basement with abundant storage potential. Despite its peaceful, estate-like atmosphere, the property is conveniently located near Cornwall's shops, restaurants, Town Park, library, and the Hudson River. Commuters will appreciate the proximity to Salisbury Mills/Cornwall and Beacon train stations, Stewart International Airport, and West Point, with New York City approximately 60 miles away. Historic homes with this combination of acreage, amenities, architectural character, and location are increasingly hard to find. 90 Quaker Avenue offers a unique opportunity to enjoy a truly special property in the heart of Cornwall.
