A rare opportunity in Whispering Ridge Estates- this isn't simply a beautiful homesite; much of the legwork involved in building has already been completed! This premium 1.31-acre corner lot offers cleared, level land in a beautiful Johnsburg setting near the Fox River, along with remarkably low holding costs- 2025 property taxes were just $1,172.34. Since purchasing the property, the owners have invested considerable time and expense preparing it for future construction, including soil testing, a plat of survey, and professional engineering for the proposed well and septic system. And here's what really sets this property apart: a complete set of custom architectural plans by highly regarded local firm ALA Architects was designed specifically for this homesite. Available for purchase separately from the sellers for a fraction of the original cost, the plans feature an impressive 2,896-square-foot home with 4 bedrooms, 3.5 baths, a main-level primary suite, English basement, and open-concept kitchen and living space. The design also includes an incredible 1,407-square-foot, extra-deep 3-car garage with a 769-square-foot attic above that could potentially be finished in the future, bringing the home to approximately 3,665 square feet of potential finished living space. It is uncommon to find a vacant homesite with this much of the preliminary work already completed. Build using the thoughtfully designed existing plans or bring your own vision and builder. With 1.31 acres, a premium corner location, low property taxes, proximity to the Fox River, and valuable testing, engineering and design work already in place, this is an exceptional opportunity to take a major head start toward building your dream home in Johnsburg.
