311 Millcreek Lane Rarely available custom-built jewel in highly desired Olesen Estates! This energy-efficient 1995 home combines timeless architectural detail including solid oak 6-panel doors throughout with massive mechanical and performance upgrades. Enjoy near-net-zero electricity costs thanks to a 1-year-old solar system. Major infrastructure is already handled: New high-efficiency Furnace and Air Conditioner (2023), plus a newer roof, skylights, gutters, and downspouts (2015). The home's envelope was professionally enhanced in 2023 with high-R-value insulation, air sealing, and weatherstripping for ultimate year-round comfort. Inside, a dramatic vaulted family room flows into a sun-drenched sunroom with skylights and a bay window. The spacious kitchen and laundry feature 2-year-old appliances (Refrigerator, Range/Stove, Dishwasher, Washer and Dryer), a reverse osmosis water system, and a mudroom with a new exterior door (2025). The master suite is a true retreat with tray ceilings and an adjoining sitting room overlooking the family room. The expansive full basement is a blank canvas-freshly painted from ceiling to floor (2024) and full of potential. Relax on your concrete patio or walk the new 1-year-old flagstone path through the garden. Minutes from Downtown Naperville, Metra, I-88, and top-rated District 203 schools.
