Iconic luxury emerges from waterfront prestige in this generational mansion on the shores of Lake Ontario in the idyllic village of Port Dalhousie, St. Catharines. Revered as the 'The Big White House in Port' and historically recognized as 'The Breakers', this three story lake house was completely restored in 2017 to make an affluent impression at every corner. Graced by cinematic views of the lake from every floor, and staged for entertainment with a chef's kitchen, formal dining room, living room and den, this mansion boasts a professionally designed interior, in floor heating, state of the art smart home amenities and a third floor 120 inch home theatre system offering wet bar with once again, panoramic views of the water. With no expense spared, and a 500 bottle wine cellar with custom cherry wood cabinets and cobblestone floors to further characterize the charm and magnificence of its historical allure. All new landscape patio stones, composite decking, and heating in garage. Visions of sea ships and sailboats and proximity to Lakeside Park beach, The Port Dalhousie Yacht Club, the Port Dalhousie Pier Marina and local shops and restaurants positions this luxury masterpiece as a one of a kind opportunity to live life to the fullest.
