1616 Riverside Avenue St. Charles, IL 60174

One-of-a-kind custom home with breathtaking Fox River views, ideally situated on a rare double lot just steps from downtown St. Charles and Geneva. Experience the best of both towns, acclaimed festivals, award-winning dining, shopping, and more, all within walking distance. Nestled in the highly rated St. Charles 303 School District, this home offers easy access to the Fox River, Fox River Trail, and parks. A long driveway leads to the beautifully designed home, thoughtfully set back from the road for added privacy and framed by a spacious front yard. Step through handcrafted copper French doors into a bright, spacious living room featuring 10' ceilings, new 2025 carpet, a generous 10' closet, and large Pella Designer Series windows that showcase stunning river views. The living room, staircase, and upper level were custom-built and thoughtfully renovated between 2004 and 2006, seamlessly blending timeless design with modern comfort. The kitchen features new granite countertops, updated stainless steel appliances, abundant cabinet storage, and a dining area. Adjacent is a mudroom with built-in cubbies and convenient access to the backyard patio. The main-level bedroom offers vaulted ceilings, skylights, built-in storage closets, and new carpeting. The main level also has a full bathroom with a tub/shower combo and a spacious laundry room for added convenience. A custom winder staircase with new carpet and elegant half-round windows offers river views as you ascend to the second floor. As you make your way up, you'll notice unique architectural details including a pressed tin ceiling, handmade custom chandelier, and custom oak railings. At the top of the stairs, tucked away above the second floor, you'll discover a secret bonus room perched inside the home's tower, accessed by pull-down stairs. With sweeping views of the water, this secret lounge is the perfect private hangout retreat away from the rest of the home, and it even has access to the flat roof, which could be transformed into a rooftop deck. The primary suite boasts a large window framing breathtaking Fox River views, 12' ceilings, an electric fireplace, a built-in safe, double closets, and hidden wraparound storage behind the walls. The third and fourth bedrooms both showcase vaulted ceilings and new carpet, with the fourth featuring a built-in loft bed and built-in storage spaces. Outside, enjoy a spacious and private fenced backyard with a brick paver and concrete patio, raised garden beds, and a cozy fire pit, perfect for outdoor entertaining or relaxing in privacy. Two detached garages provide abundant storage and exceptional flexibility: a heated and insulated 2-car garage with loft storage, and an expansive 3-car garage (36x24, built in 2021) with high ceilings and the potential to add power and plumbing for an ADU conversion. Built with exceptional quality and attention to detail, this home offers both long-term durability and outstanding energy efficiency. Exterior highlights include James Hardie siding, copper roof ridges, custom copper gutters and downspouts, and 50-year architectural shingles paired with R-38C roof insulation for superior performance. Inside, the construction is equally impressive, with 10-inch-thick walls, R24 insulation, R30 insulated foundation walls, and 20% more drywall than standard builds, providing excellent temperature control, sound insulation, and remarkably low utility bills. Every detail speaks to quality, from solid 13/4-inch doors throughout to hardwood floors upstairs with cork underlayment for quiet, comfortable living. Radiant heating pipes have been installed in the slab and zoned for future hookup. Major updates include a new furnace and water heater in 2020 and new roof in 2019. Overlooking the picturesque Fox River, this home offers scenic views, exceptional privacy, and an unbeatable location near downtown St. Charles and Geneva, offering a lifestyle of comfort, convenience, and a connection to nature and community
