Maybe the auctioneer is calling this Standard Properties 1950s contemporary bi-level a colonial because of the added portico. In any event, it is being sold at an estate auction tomorrow (June 10) at 1 p.m. The auction will be at the property, which is located here in Rock Creek Palisades in Kensington, which also includes Charles Goodman’s mid-century modern community of Rock Creek Woods. Starting price will be determined at sale time. The house looks mostly untouched except for that portico.
