Brock Commons Tallwood House is an 18-storey student residence at the Point Grey Campus of the University of British Columbia (UBC) in Canada. At the time it was opened, it was the tallest mass timber structure in the world. It is the first phase of a complex at Brock Commons. The Brock Hall Annex located at the site will be demolished to make way for a building in phase 2. The 1958 mosaic mural "Symbols of Education" by Lionel and Patricia Thomas, commissioned by the university's 1958 graduating class, will be moved as a result.
