Sadleir House is a community centre operating out of its 1892 Queen Anne style heritage designated property in Peterborough-Nogojiwanong.  Operated by the P. R. Community & Student Association (a registered charity), Sadleir House provides space for performances, meetings, studying, reading, film screenings, gallery showings, offices, libraries, and so much more. Sadleir House became independent from Trent University in 2004 but continues to serve as an important bridge and meeting place between university students and the wider community.

Donations to the Sadleir House Fund will support regular operations and ongoing maintenance projects of the 12,000 square foot space and help keep heritage features in good repair so generations of young people can benefit from extracurricular mentorship, leadership building, and creative collaborations in a unique community space.
