Penmarch Place stands as one of Sioux Falls’ most iconic and architecturally significant estates, offering an extraordinary blend of history, elegance, and modern-day livability. Designed in 1926 by acclaimed architects Larson & McLaren, this distinguished English-inspired residence is set behind a winding, tree-lined drive that reveals a stately three-story home surrounded by exceptional privacy. From the striking Flemish bond brickwork and sandstone detailing to the copper accents and slate roof, every element reflects a level of craftsmanship rarely found today. A circular drive anchored by a timeless sundial welcomes guests to an estate designed for both grand entertaining and intimate living. The grounds unfold as a private sanctuary, featuring a swimming pool, greenhouse, tennis and basketball court, expansive terraces, a solarium, and a terrazzo dance-floor patio—creating an unparalleled setting for gatherings and quiet moments alike. An additional garage and workshop provide flexibility for collectors, hobbyists, or future possibilities. Inside, Penmarch Place showcases imported Italian tile, original leaded-glass windows, and beautifully preserved architectural details that honor its storied past. Formal reception rooms flow effortlessly into the library, sitting room, solarium, and elegant dining room, while Portuguese cork-insulated walls and exceptional construction materials underscore the home’s remarkable quality. More than a residence, Penmarch Place is a once-in-a-generation opportunity to own a landmark estate—one that offers timeless beauty, enduring craftsmanship, and a legacy unlike any other in Sioux Falls.
