 The improvements were complete by April 1877, with the centre block expanded and its main facade altered to more of a Queen Anne style blended with a modified Elizabethan.Two story brick piers enhanced the corners and framed tall narrow windows, with the main entrance protruding forward, flanked by banded columns, more typical of Jacobean style.An octagonal cupola surmounted the main entrance volume, surrounded by narrow pinnacles topping the corner piers, which all concealed chimneys and ventilation openings.
