There are four major stages of construction, following the demolition of the 1871 slab barn - 1876, 1884, 1903 and 1913. These construction dates embrace different architectural style which are expressive of the separate eras in which each part was built. The School of Arts as it exists today, is really a complex of separate buildings. The original part of the existing school of Arts complex, consisting of a Hall and Reading rooms built in 1876, was the culmination of community effort following the establishment of a Reading Room in 1863 by Edward Reeves Whereat when the township was barely ten years old. In 1884 the building more than doubled in size with the addition of a No. 2 Hall to the east, a new
bay to the south and gabled frontispieces to the Rouse St facade. These elements were constructed in a mixed
Victorian Rustic Gothic and
Victorian Romanesque styles. The Main Hall in
Federation Free Classical style, completed in 1903, is a memorial to men from Tenterfield who gave their lives during the Boer War, 1898–1901. The Billiard Room, designed by F. J. Madigan, was completed in 1913 towards the end of period uniquely nationalist architectural expression not known as the Federation Style. The local community and The National Trust in recognising the significance of the site and maintaining, its original characteristics have maintained the integrity of the building.
