The fonds consists of architectural drawings. This material documents a small portion of the life of John Schreiber as a physical and landscape architect. It consists of a number of drawings, as well as the files containing specifications, proposed and final, used by John Schreiber in the design of two residences located in the Thousand Islands region of the province of Ontario, for patrons Mr. Robert Hewitt, and Mr. and Mrs. C. Vandendries. The two examples of his work provided here are tangible examples of how John Schreiber incorporated his ideas of style and landscape in order to blend these structures perfectly into the unique geography known as the Thousand Islands.
