About this home

Commanding an extraordinary stretch of Winnipesaukee shoreline, on approximately 30 acres, North Ledges at Welch Island is one of the lake’s most compelling island estates. Encompassing three distinct waterfront parcels with roughly 3,000 feet of shoreline, this remarkable compound combines exceptional privacy and panoramic views, on a scale rarely found on Winnipesaukee. The estate unfolds across a beautifully wooded landscape, with walking trails connecting its residences, recreational amenities and extensive waterfront. A magnificent stone boathouse, substantial breakwater docking, expansive Ipe deck with integrated seating and McIntosh audio system, multiple sandy-bottom swimming areas and exceptional water access create a waterfront environment designed for generations of boating, swimming and gathering. A tennis/pickleball court, private gym, formal garden, and numerous outbuildings further distinguish the property. At the heart of North Ledges is a timeless six-bedroom lake house offering more than 4,000 square feet of classic Winnipesaukee character. Rich wood interiors, a grand wood-burning fireplace and gracious gathering spaces are complemented by an expansive chef’s kitchen designed for entertaining and a spacious sunroom overlooking the lake. Several bedrooms open to private sleeping porches, creating quiet retreats surrounded by water and nature. Two additional waterfront cottages provide exceptional flexibility for family and guests. A charming three-bedroom cottage features a spacious lakeside deck with hot tub, substantial breakwater docking and an established rental history. A staff cottage on the third parcel preserves the simplicity and character of traditional island living. North Ledges is more than a remarkable collection of waterfront properties. It is a private island estate of uncommon scale and beauty, offering the rare ability to gather generations together while preserving the space, privacy and authentic connection to Winnipesaukee.
