“The Wedge” – Iconic Blue Heron Bay Waterfront! Featured in Sunset Magazine, this one-of-a-kind architect-designed home delivers an extraordinary Oswego Lake lifestyle in a remarkably efficient footprint. Set on the beautiful deep waters of Blue Heron Bay, its dramatic wedge design expands from just 19 inches at one end to approximately 18 feet at the waterfront, with three levels, two mezzanines and a striking steel staircase at its core. Renovated in 2021, the home features 3 bedrooms, each with its own bath, plus a guest powder room, chef’s kitchen, hardwood floors, heated bathroom floors, skylights, custom wood vanities and abundant integrated storage. Enjoy expansive bay and canal views, a rooftop boathouse party deck, hydraulic boat lift and additional waterfront space for a guest boat. The top-level primary suite offers a private, treehouse-like retreat overlooking the water. A recently completed detached ADU with kitchenette, full bath and laundry provides exceptional flexibility for guests or office space. Cedar and Ipe decking, generous parking and two extra-deep spaces for boat trailers complete this truly unique property. A rare townhome alternative offering big-water living, architectural character and direct access to everything Oswego Lake has to offer.
