This tiny gray store at the corner of Old Georgetown Road and Greentree Road in Bethesda, MD has been around forever (Actually "only" since 1924). For some reason, when I was a kid it was called "Browns" although I never knew why (was the owner named Brown?) Even back then it was called Bethesda Community Store and was painted gray.
For some time, the current owner, Arnie Fainman, has been trying to expand. Earlier this year the Montgomery County Circuit Court ruled that the store should "be preserved and that its economic viability be protected to enable to continue in operation as a ‘store.'" This opens the path for him to expand. Any plans still have to be approved by Montgomery County Historic Preservation Commission and in the past expansion has been opposed by the Huntington Terrace Citizens Association saying it represents an unwanted commercialization of the area. They haven't decided if they will continue to oppose the expansion.
Fainman wants to allow the Salt River Lobster company to continue to sell seafood on the store's property, and to be able to turn the storage shed into a permanent building expansion.
There is a whole lot more information at the Gazette.
