Crowning the knoll at Edgemont Street and Los Feliz Boulevard is a 21-room Italian Renaissance mansion, built in 1912 as the marital home of newlywed Edna Letts (whose father owned the land) and Malcolm McNaghten.

At the Edgemont approach, stone steps ascended thirty feet in a series of flights, each marked by an urn planter and lamp post. Cypress trees beautified a seven-foot retaining wall supporting a grass terrace. The surrounding two-acre lawn boasted formal gardens, fruit trees, marble fountains, and concrete walks.
