Home For Sale

Welcome to Cathedral Rock, a truly unique lakeside retreat steeped in history and set on 8.2 acres with 330 feet of frontage on Portaferry Lake. Once the site of a Boy Scout camp from 1947 to 2006, this remarkable property blends rich heritage with modern luxury. Its namesake, Cathedral Rock is a towering boulder that rises near the house and is where scouts once gathered for spiritual services and outdoor climbing activities. The main residence, constructed in 2015, is a custom designed contemporary home offering a blend of modern amenities and rich architectural character. This thoughtfully crated two- bedroom, three bath and one-half bath home features granite countertops, a stainless-steel kitchen sink, two antique stained-glass windows, an antique transom window from Argentina, a vaulted living room ceiling, and a historic fireplace mantel from the Waldorf Astoria. The spacious primary suite offers an en-suite bath, a cozy sitting area, and large picture windows with serene views of the lake. Also upstairs, a bridge offers elevated access to Cathedral Rock. The fully finished walkout basement features a professionally outfitted home gym, a full bath complete with a built-in sauna and steam room, a media room and access to an outdoor patio- perfect for entertaining. An attached garage provides convenient access and completes the main residence. Alongside the main house, there is a beautifully renovated 697 sq ft guest house that was once a camp counselor's residence. Thoughtfully updated, it includes its own kitchen, full bath, comfortable living area, and private bedroom. Enhancing the property's appeal, perennial flower beds surround the home, while extensive professional landscaping integrates a nearby stream into the design. The private lakefront with 330 feet of frontage offers an expansive view and includes a permanent dock, sitting platform, a rustic lean-to and a private beach. This home is being sold fully furnished.
