Oak Lawn Heights remains the largest single-family neighborhood in Oak Lawn, which has been increasingly dominated by highrise, retail and office development. This neighborhood of Tudor cottages with steeply pitched roofs and stained glass was developed in the 1920s and annexed into Dallas in 1929. The early settlers coveted this high ground for which Oak Lawn Heights is named. After a slight decline from the suburban flight in the 1960s, there has been a several decade positive trend of reverse migration.
