870 University Drive is a one of a kind house. Built for Herman Pettit, designed by Frank P. Martin, the impressive house remains as a reminder of the boom years (1910-12) in Saskatoon. The most unusual feature is the porte-cochere (carriage entrance), which stretches over the front driveway.
Herman Pettit left Saskatoon in 1915, probably another victim of the bust that followed the boom.
Dr. George Sommerville (a dentist), purchased the house in 1918. The house was converted into three suites. Each floor became a suite, two staircases were added. Dr Sommerville died in 1936 after which Mrs Sommerville continued to live in the house. It has been largely restored to once again become a gracious dwelling with the charm of an earlier era.
