Welcome to Tria Rotunda (latin for “three rounds”)! Nestled in the picturesque landscape of Stone Ridge this captivating modernist gem stands out with its distinctive architecture - three interconnected cylinders that harmoniously blend with the surrounding natural beauty. This 3-bedroom, 2.5-bath home offers a refreshing and unmistakably bohemian feel, with a touch of West Coast ambiance, that exudes retro charm. The property's striking stucco exterior is composed of three cylindrical structures, contrasted by the sharp right angles of the 2-car garage. The curvilinear design showcases a harmonious blend of modernity and nature, where the use of sleek lines and a subdued color palette creates a seamless connection between the home and its lush surroundings. Large, strategically placed windows invite natural light to flood the interior spaces and offer glimpses of the vibrant outdoors. Upon entering, the interconnected cylindrical floorplan creates a subtly psychedelic experience, a wow moment combined with a dash of disorientation. The modernist design effortlessly combines contemporary aesthetics with a retro twist and the interior spaces are bathed in warm, natural light, highlighting the home's open layout. The first cylinder embodies the communal spaces of the home - living, dining and kitchen. The spacious living room is a comfortable and inviting space, perfect for relaxation and entertaining, anchored by a statement fireplace with stacked bluestone surround that adds a cozy ambiance on cooler evenings. The open-concept design seamlessly connects the living room to the dining area and kitchen, creating an ideal environment for gatherings and entertaining. A second cylinder encompasses the primary bedroom, which offers a serene and restful atmosphere complete with a sitting area and en suite bath. Large windows provide tranquil views of the surrounding landscape, allowing you to wake up to the beauty of nature every day. A third cylinder houses the additional two bedrooms which share a jack-and-jill full bath. Tria Rotunda offers outdoor spaces that seamlessly integrate with the property's natural surroundings. At the interstices of the three cylinders are doorways to the outdoors - the double-door entrance with front porch, a side door that leads to the garage via covered walkway, and the double-door access to the brand new deck and verdant, fully fenced backyard. The spacious deck and screen porch provide an ideal setting for alfresco dining, entertaining guests, or simply unwinding while taking in the lush beauty of the property. Recently updated with a new roof, new electric heat-pump central AC, solar panels and much more, Tria Rotunda is ready for you to move right in to this one-of-a-kind residence and start enjoying your country escape that combines modernist architectural sensibilities with a distinctly bohemian design. The unique trefoil structure, thoughtfully designed living spaces, and integration with the natural surroundings create a harmonious blend of serenity, style and sophistication. Ideally situated in desirable Stone Ridge, only moments from the town center and just 90min from the GWB, Tria Rotunda enjoys the best of both worlds - a tranquil retreat that is completely private and hidden from the road but within easy reach of amenities (right down the street from Cherries!!!). Within minutes, find yourself dining at Butterfield, enjoying a round of golf at Inness or shopping for local produce at the High Falls Food Co-op - the location can’t be beat!

Unique contemporary home with mid-century vibe in private setting in historic Stone Ridge. This 3 bedroom 2 1/2 bath home on a large one acre lot is surrounded by cedar trees offering good privacy yet still only minutes to every convenience Stone Ridge offers. Lots of natural light and one of the most interesting layouts comprised of 3 distinct circular wings of the home. Must be seen to be appreciated, fairly well maintained but some updating needed. Large 2 car garage is outfitted for heat and would make an excellent workshop or studio. Large shed adds to the storage space here that most homes lack. Great southern exposure and a very large fenced in garden just perfect for anyone with a green thumb. Extensive decking makes entertaining friends and family a breeze. Stone Ridge, in the Rondout Valley, offers up something for everyone - it is a small town community with a big quality of life. Set amidst some of the most popular Ulster County hotspots of High Falls, Rosendale, Kingston and New Paltz; all roughly within 15 minutes away, mean that nothing is too far from reach. Artistic types will thrive here, with lots of nearby galleries and festivals, flea markets and craft fairs and unparalleled natural beauty. The proximity to protected Mohonk Preserve and Minnewaska State Park, as well as plenty more parks and swimming holes makes this Catskill mountain getaway something to consider. Being in the heart of the Rondout Valley also means the freshest Hudson Valley produce is right outside your door- visit Davenport Farms, Kelders Farm, Saunderskill Farms, Stone Ridge Orchards, Westward and many more, only minutes away. Immerse yourself in country living, while still only being less than 2 hours from New York City. This is an excellent opportunity for someone looking for something unique and special, something out of the ordinary and not often seen on the market at such an affordable price. Black top driveway and full basement complete this rare offering. This is an estate sale and owners are motivated and ready to make a deal. Easy to show, contact your agent for more details.
