In the University at Buffalo Archives, Heritage Landscapes studied photographs, receipts and diary records with construction details and specific dates of plantings. One photograph shows water spilling from a basin under the port-cochere into the rock-lined pool in July 1928.

Heritage Landscapes highlighted the boulder edge and circular drive shown in Wright's 1927 sketch for the pool area to understand the forms.

A Wright plan received by landscape architect Ellen Biddle Shipman in 1929 includes a note directing pool removal.

A 1930 Shipman plan proposes a redesign of the pool area with lawn and three apple trees.

By 1932, a photograph reveals change: the sealed basin outlet is planted with shrubs and the pool is removed.

Historical period plans can be developed and compared to current conditions for guiding restoration efforts and educating visitors on the relationship between past and present landscapes. The 1931 Period Plan encompasses the intersection of Wright and Shipman landscape designs prior to the removal of the pool.

Line drawings that overlay 1931 and existing conditions provide direction for restoration treatment recommendations. Analysis of plans reveals more than the presence of remaining historical features; it also depicts changes in circulation and canopy density. This information carries implications for many other aspects of the site including historical experiences of sun and shade, views and visual relationships, and hydrological function.

The 2005 Existing Conditions Plan illustrates the starting point for restoration treatment that aims to restore the character of the property to 1931.
