The original buildings were opened in the early 1960s but further development has taken place on a regular basis ever since, such as the library, information technology rooms and science facilities as well as the post-16 learning centre. Treviglas opened a new sports facility, The Dome, in October 2001 and, in February 2004, a new dedicated sixth form and community learning block was opened. The SportsHub, funded by Sport England, opened in 2012. From the playing fields there are views to the sea dropping down toward Porth, with the village of St Columb Minor neighbouring the college.
