One of the storied properties in the Tall Timbers niche of River Oaks quietly arrived on the market this week. Restrained and almost dainty in its design by the then in-demand architect Hiram Salisbury, the 1941 main building features columns and balconies accenting a brick exterior. The east-wing addition in 1950, meanwhile, was by another go-to architect: John Staub. The resulting work by 2 premier architects blended in one estate sits on a large lot measuring more than an acre and a half. All that land can be subdivided, “for 2 building sites, already approved” by the River Oaks Property Owners association, the listing says. The asking price is $8.1 million.
