Document 6: Janes &amp; Leo: Janes & Leo was the New York-based architectural firm of Elisha Harris Janes and Richard Leopold Leo (1871/72 — 26 September 1911). From 1898 to 1911, the firm designed and built numerous Beaux-Arts residential structures in New York City, both richly detailed row houses and luxury apartment blocks during the building boom that constructed Manhattan's Upper West Side. Though neither Elisha Harris Janes nor Richard Leopold Leo ever studied at the École des Beaux-Arts in Paris, they worked within its traditions. Their most prominent structure is the ebullient Dorilton (1902), at Broadway and 71st Street, bolder and more sculptural than any professor at the École des Beaux-Arts would have encouraged. Montgomery Schuyler, the critic for the "Architectural Record", disapproved of its flamboyant appeal:

Although the Great Depression forced Rockefeller to suspend operations, following World War II others were drawn to Forest Hill to build comfortable colonial and contemporary ranch homes on the remaining open land. Design principles of the Rockefeller-Thomas plan were extended to the later development and today Forest Hill is a rich tapestry of people, homes and gardens.

Document 15: Wallace E. Pratt House: The Wallace E. Pratt House, also known as Ship On The Desert (sometimes hyphenated), was the residence of Wallace Pratt in what is now Guadalupe Mountains National Park in far western Texas. Pratt, a petroleum geologist for the Humble Oil & Refining Company, had previously built the Wallace Pratt Lodge in McKittrick Canyon a couple of miles to the north in the Guadalupe Mountains. Finding the cabin site to be remote and prone to being cut off by flooding, Pratt started construction of a new, modern residence on the east slope of the mountains. Work on the residence started in 1941. The house was designed by Long Island architect Newton Bevin, who lived for a time at the site with his wife, and built by contractor Ed Birdsall. Work was stopped by World War II, but resumed in 1945 and was completed the same year. In contrast to Pratt's rustic canyon cabin, the house, which Pratt named the Ship On The Desert, is an International Style house with horizontal lines and extensive glazing. Only 16 ft wide and 110 ft long, the house provides broad views to the east over the plans and the west to the mountains. The majority of the house is on a single level, with a "captain's bridge" over the dining room giving access to a rooftop terrace. A detached garage contained a guest bedroom. Apart from glass, the predominant material was local limestone in several shades.
