702 Indiana Avenue An In-Town Oasis Where Sustainability Meets Timeless Charm. Known affectionately by local Master Gardeners as Tranquility, this remarkable property offers a rare blend of historic character, environmental stewardship, and breathtaking gardens--all within walking distance of downtown Valparaiso and Valparaiso University. Set across two city lots, this late-19th-century home has been thoughtfully renovated and expanded between 1995 and 2011, creating approximately 3, 900 finished square feet on four furnished levels. Original woodwork, solid oak joists and studs, hardwood and parquet flooring, and a decorative tin ceiling celebrate the home's heritage while modern systems provide exceptional comfort and efficiency. Energy-conscious buyers will appreciate the property's impressive sustainability features, including geothermal heating\cooling, a new geothermal compressor installed in 2023 with the system professionally inspected in March 2026, roof-mounted solar panels, and an electric vehicle charging station in the garage. The solar array produces electricity that is sold back to NIPSCO, generating monthly income for the homeowner through a transferable agreement. Hidden behind mature privacy hedges, the grounds showcase perennials, flowering trees, shrubs, specimen conifers, and enchanting garden rooms connected by winding flagstone walkways and arched garden entrances. Expansive decks, patios, and a charming screened gazebo provide idyllic spaces for morning coffee, outdoor dining, entertaining guests, or simply enjoying the sights and sounds of nature in complete privacy. Vinyl and natural fencing, along with an underground sprinkler system, help maintain the property's park-like setting with ease. Inside, the home's most enchanting feature may be the year-round solarium with wave pool, offering a private sanctuary regardless of season. Additional highlights include a security system, a five-year-old architectural shingle roof, second-story awnings, and paver drive.
