The construction of structures continued in the first decade of the 20th century. The neoclassical Peristyle (1904), Boathouse (1905), Tennis House (1910), and Willink Comfort Station (1912) were all designed by Helmle, Hudswell and Huberty, alumni and proteges of McKim, Mead, and White. The entrances into Prospect Park that were constructed during this time were also in the neoclassical style. Two now-demolished structures were also constructed on the peninsula, the Model Yacht Club House (1900–1956) and a shelter (1915 – ). Olmsted was said to have been "distressed" by these modifications to the park's original plan.
