El Retiro – H.E.C. Webb Residence, T.M. Webster, Architect. A rare 1911 historic sanctuary in the heart of Sierra Madre, steeped in over a century of local history, 171 S Baldwin Ave stands as a captivating testament to the early 20th-century architectural heritage of Sierra Madre. Offered for sale for the first time in over 50 years, this singular estate presents an extraordinary canvas for the preservationist or vintage-home purist looking to celebrate classic California character. Commanding a generous 2,507 square feet (taped) of living space, the residence opens to a sweeping 13,291 sq. ft. lot, framed by mature trees–offering an expansive, private garden sanctuary that evokes the peaceful atmosphere of a bygone era. Boasting a stately facade, high-volume ceilings, expansive vintage windows, and a floor plan rich with original woodwork and natural light. The rare, oversized lot provides an authentic estate-like feel with ample room to curate a traditional English garden, restore period-accurate hardscaping, or construct a matching carriage house or artist’s studio. Tucked away in a deeply historic foothill community celebrated for its architectural tours, vintage village center, and deep appreciation for historic preservation. Located just steps from the iconic boutique shops and local cafes of downtown Sierra Madre, and minutes away from the legendary foothill trailheads, this property is a rare find. For the buyer who values character over conformity and history over the ordinary, 171 S Baldwin Ave is ready for its next great chapter.
