In 1927, the Landscape Engineering Division of the National Park Service San Francisco office created a development plan to give ""a sense of order"" to the buildings the government and concessionaires had built in the Longmire Plaza area south of the road. Three particularly significant buildings came about as a result of this plan, each of which demonstrated the National Park Service efforts to construct structures ""that harmonized with the rugged slopes of Mount Rainier"". The Community Building (1927) is a good example of early National Park Service Rustic style. The use of pairs of columns rather than the notched corner technique shows a particular skill in using natural minerals. The Administration Building (1928) is said to be the most architecturally significant of the buildings from this period. Features such as the heavy masonry first floor and timber second story were influenced by the 1924 administration building at Yosemite. Careful selection of local boulders was important in achieving a building that matches the surrounding landscape. The Service Station, built in 1929, is the last of these three buildings. It was designed to be unobtrusive in its natural setting.
