In 1915 the 73 acre third addition was developed with large lots. This architecturally significant neighborhood is most closely associated with the 56 acre Dallas Country Club, the oldest Country Club in Dallas. The Fairfield street boundary runs along the fairways of the Dallas Country Club. Mockingbird and Beverly both have entrances to the clubhouse. Drexel and Hackberry Creek make up the final boundary.

Beverly Drive is considered one of the most prestigious addresses and a street associated with magnificent homes. Maplewood and Stratford are many people's favorite streets. They are also wide, but have no through traffic since they end at the golf course and Hackberry Creek. Many of the original homes have survived and are as gracious as ever.
