SASKATOON The 500 block of 11th Street East near Broadway Avenue is known as a hidden historic gem in the city. “Because it evolved over time, it has representation from almost every building era,” researcher Dianne Wilson told CTV News. That is unique in a city that doesn’t always value old in favour of new, according to Wilson. “In the older neighbourhoods there has been so much recent demolition and infill,” she said. No new buildings have been constructed on the block since 1950. The styles include a 1911 brick house with a truncated hipped roof, which once had an exposed porch that was closed in because of cold weather for more than half the year and mosquitos in the summer.
