EXECUTIVE WATERFRONT LUXURY | UNMATCHED SCALE & PRESTIGE | 9441 SQ FT OF PURE 2023 EXCELLENCE - Welcome to the most extraordinary custom waterfront estate ever offered in Grand Bend: a next-level masterpiece sitting on 3 acres w/ over 177 ft of peaceful Ausable River frontage. This is ultra-premium living for upper-tier buyers who demand a home that simply doesn't exist anywhere else. Inside this 9441 SQ FT architectural triumph, every inch is finished at a standard beyond premium. The showpiece is the 4-season sunroom, a full "home within a home," featuring a built-in swim spa pool, the largest custom skylights available, & exclusive roll-up screens unseen in any other residence in the region.

The entire main & lower level floors are heated along with the garage, which is a car collector's dream offering 5 bay doors & floor space for 6 cars + storage. A double-deep RV/boat bay in the garage leads to a on site private boat launch adjacent to 50 ft of private dockage already in place + ample space to grow for larger boats or additional watercrafts. With the extremely private 3 acres, there is an abundance of land for a large hobbyist shop or development potential near the road for an additional lots.
