Overview

Tucked away at the end of a private cul-de-sac and set well back from Black Rock Road, this remarkable residence offers a rare combination of privacy, architectural pedigree, and natural beauty in the heart of Gladwyne. Situated on 2.6 acres within the award-winning Lower Merion School District, the home enjoys wooded views from every room and a serene connection to its surroundings. Originally designed in 1937 by architects Douglas Braik and Robert Montgomery Brown, it is a striking example of early International Style architecture, a precursor to the Mid-Century Modern movement. Defined by clean lines, flat rooflines, and expansive bands of windows, the stucco-on-masonry façade, geometric forms, and light-filled interiors embody timeless modern design decades ahead of its time.
