Rathsillan House is a truly exceptional lakeside residence, perfectly positioned on an elevated site of approximately 1.1 acre, with uninterrupted panoramic views over the shimmering waters of Lough Sillan. This magnificent 6 bedroom, 7 bathroom Georgian inspired home is a masterclass in timeless design, luxurious living, and precision engineering, offering a rare blend of classical elegance and contemporary convenience. Built just 17 years ago to the highest specifications, this substantial property spans over 434 sqm (4,674 sq ft) across three beautifully appointed levels, with an additional 144 sqm (1,549 sq ft) of flexible space in the detached, double-storey garage.

Approached via new electric gates, the avenue leads you to the home’s symmetrical façade, framed by ivy-draped gables and bay windows, makes an instantly graceful impression. The house’s design cleverly balances its classic Georgian styling with the demands of modern living and once inside, the full impact is breathtaking. A soaring double-height atrium greets you on arrival, setting the tone for the home’s expansive proportions and light-filled interiors.

Inside, the home exudes refined comfort and timeless elegance, with marble and solid hardwood flooring, a bespoke wall-to-wall library, and a seamless open-plan layout that flows effortlessly from one end of the home to the other. Expansive floor-to-ceiling picture windows frame unobstructed views of Lough Sillan, drawing the eye outward and flooding the interiors with natural light. At the heart of the home lies a custom-designed kitchen, featuring a generous island, bespoke cabinetry, and premium NEFF appliances, all centred around a double-sided hardwood stove that warms both the kitchen and adjoining living areas. Underfloor heating throughout ensures year-round comfort, while granite fireplaces, luxurious bathrooms, and meticulously chosen finishes underscore the home's sense of understated opulence. Some of the bedrooms offers access to a terrace or balcony, with the upper levels enjoying the most commanding views of the lake and surrounding landscape.

An entertainer’s dream, Rathsillan House features extensive viewing and entertainment terraces on both the ground and lower levels, perfect for hosting guests or simply soaking in the natural beauty of the surroundings. The basement level, measuring just under 100 sqm, includes additional living, games, and recreation spaces ideal for families or visiting guests. The detached garage, built to the same standards as the main residence, includes underfloor heating too, offering even more flexibility as a home office, studio, or guest accommodation (Subject to PP.)

Outside, the grounds have been landscaped for both beauty and privacy. Mature trees line the boundary, while manicured lawns gently slope down toward a spectacular 665 sq ft private jetty, complete with a hydraulic boat lift. Whether it’s morning coffee by the water, afternoon picnics, or sunset cocktails, the south-facing jetty offers the ultimate in lakeside living. Lough Sillan is renowned for its vibrant water sports community, with boating, waterskiing, jet skiing, kayaking, and more right at your doorstep.

Purpose-built for both relaxation and refined entertaining, it offers the perfect balance of elegance and adventure. Boasting a Green BER rating, solar panels, enhanced insulation, and a suite of cutting-edge technologies, the home delivers sustainable luxury without compromise.
