This late Georgian house, begun in 1818, was built by the Corps of Royal Engineers as the residence and offices of the Assistant Commissary General stationed in St. John's . From 1821 to 1870 it was the premises of the officer responsible for the pay, supplies and services required by the British military establishment in the town. After withdrawl of the garrison in 1871, the Anglicans used it as the rectory of St. Thomas "The Old Garrison Church". It served as such until 1969 except for the period 1918-21, when it was a nusing home and hospital. The house is restored to about 1830 and the garden to mid-century.
