Penmarch Place is among Sioux Falls' most distinguished and historically significant estates. Originally constructed in 1926 and designed by renowned architects Larson & McLaren, this English-style residence showcases timeless architecture, exceptional craftsmanship, and remarkable privacy. A winding tree-lined drive leads to the stately three-story home, where classic details include Flemish bond brickwork, sandstone trim, copper accents, a slate roof, and a circular drive centered by a sundial. The estate grounds create a private retreat with a pool, greenhouse, tennis/basketball court, additional garage with workshop, and expansive outdoor living spaces including a solarium and terrazzo dance floor patio designed for entertaining. Inside, imported Italian tile, original leaded glass windows, and richly crafted finishes reflect the home's enduring character. Formal reception rooms connect seamlessly to the sitting room, library, solarium, and formal dining room. Portuguese cork-insulated walls and premium construction materials throughout further speak to the estate's extraordinary quality and preservation. Penmarch Place represents a legacy property of rare significance, offering the opportunity to own one of Sioux Falls' most celebrated historic estates.
