Until 1890, Tenleytown was a rural crossroads, but the arrival of the electric streetcar and the Permanent Highway Plan spurred suburban development. Real estate promoters advertised new houses on the town’s high ground as offering city conveniences, country charm, fine views, and a 25-minute ride to downtown. Developers Ernest M. Pease and Colorado Senator Thomas M. Patterson acquired land between the Wisconsin Avenue and Connecticut Avenue streetcar lines and in 1904 promoted their subdivision, Colorado Heights, to middle-income white workers, with homes priced at not less than $2,500. Although Tenleytown had police and fire protection, electric lights, water, and sewers, growth remained slow until after World War I. The Warren brothers then bought many of Patterson’s lots and built three blocks of battleship gray, two-bedroom bungalows, many with front porches or sleeping porches. These blocks preserve the look of the 1920s and contrast with the upright brick Colonial houses that became popular in the 1940s. In Tenleytown, the Permanent Highway Plan followed the lead of real estate developers who imposed a grid on the older curving streets, and later changes erased parts of Grant Road and other country lanes while renaming others. The introduction of Nebraska Avenue in the 1930s and Brandywine Street in the 1950s led to the demolition of the old Nebraska Market at Brandywine Street and Grant Road.
