 In 1774 the house was purchased by Major Joseph Peavett, an Englishman, who added the wood-frame second story, and put glass windows into openings previously only enclosed by wooden shutters.It was further enlarged by the third owner, Geronimo Alvarez, who added a two-story wing built of coquina.The house was taken over by the St. Augustine Historical Society in 1918, which undertook its restoration to a late 19th-century appearance in 1959-60, reversing a number of intervening alterations.
