As early as 1910, Key & Seal was endeavoring to move to Prospect Avenue, to the empty lot just east of Charter Club. The first proposal is known through the Class of 1911 Bric-a-Brac (1909-10), which reproduced a drawing of a Tuscan- style villa. This structure bears a strong resemblance to Raleigh Gildersleeve's Elm Club of 1900, an Italianate Revival design.
