A Rare Legacy Estate. Nearly 40 acres within city limits where extraordinary privacy, distinguished architecture and remarkable natural beauty converge. Beyond a private, tree-lined drive, the residence emerges amid mature woodlands, reconstructed tallgrass prairie, tranquil ponds and abundant wildlife. Thoughtfully sited to capture both sunrise and sunset, the home showcases timeless craftsmanship through expansive windows, soaring ceilings, marble floors, a Swarovski chandelier, bespoke millwork and a sweeping freestanding curved staircase. A chef's kitchen, executive offices, an exceptional primary suite and ensuite bedrooms provide refined comfort. Elegant, yet inviting, the living spaces are equally suited to everyday living, intimate gatherings and gracious entertaining. A rare offering, this is more than a luxury residence—it is a private sanctuary for single or multigenerational living, stewarded and cherished across generations.
