Designed by renowned architect Robert Srote of Srote & Co. Architects and expertly built by R. G. Apel, every element of this home was thoughtfully executed with no expense spared. A true centerpiece of the home is the remarkable 5,500-gallon aquarium—believed to be the largest residential aquarium in Missouri—creating a dramatic, one-of-a-kind focal point that elevates the entire living experience. Constructed with concrete between the main and second levels, the home offers exceptional sound insulation and structural integrity, complemented by radiant heated floors throughout most living areas for year-round comfort. Every bedroom is a private en-suite, offering comfort and privacy for both family and guests. A 5-car garage adds to the home’s functionality and scale. The expansive lower-level gymnasium is a blank canvas for luxury recreation—perfectly suited for a golf simulator, private bowling lane, indoor pickleball court, or a custom entertainment venue tailored to your lifestyle. Set on 1.658 acres backing to deep woods, the outdoor setting is both private and breathtaking. A resort-style natural pool with waterfall, room for a sports court, and serene surroundings create an unmatched retreat experience. Enhanced by geothermal HVAC, state-of-the-art mechanical systems, and superior construction standards throughout, this home represents a rare opportunity to own a truly distinctive property where design, innovation, and lifestyle converge. Homes of this caliber rarely become available in Frontenac.
