There are historic downtown neighborhoods, and there's Palmcroft, one of the oldest and grandest collections of midcentury homes in the city. That's because Palmcroft, roughly bounded by Seventh and 15th avenues between Thomas and McDowell roads, is something other than a mass-planned subdivision. Both Palmcroft and its nearest historic neighbor, the Encanto neighborhood, are examples of the Garden City design principle, a comprehensive approach to suburban planning that includes a unification of architecture, community planning, and landscape design. It's an approach that has its roots in 19th-century suburban planning, which typically included innovative street plans, superior landscaping, and ornamental light fixtures — all combined in this single square mile to absolute perfection.
