|The Denrike Building is an eleven-story office building on the west side of Vermont Avenue just north of McPherson Square in downtown Washington, D.C. constructed in 1925-26. Designed by notable local architect Appleton P. Clark, Jr., the Denrike Building is executed in a Tudor Gothic Revival style of architecture, a style rare for this city's commercial building fabric. As one of a collection of 1920s office buildings and financial institutions surrounding McPherson Square, the Denrike Building represents the northernmost edge of the city's financial district as it spread north from lower 15th Street around the Treasury Building to McPherson Square. The Denrike Building replaced the 19th century residence of former House Speaker Joseph Cannon (House Speaker from 1903-1911) on the site. The Denrike Building is illustrative of the wave of 20th century commercial development that replaced older and well established residential building stock in the city's downtown that had, during the 19th century, been home to the city's most prominent and affluent residents.
