If they're just replacing windows and doing some facade restoration, then it's disappointing because the building's issues at sidewalk level are beyond aesthetics. Overall, I like the Sheraton Centre's architecture, but the architecture at street level is terrible. It's mostly anonymous windows and concrete walls for a long block on Queen Street, but also on the other side on Richmond Street, and on a block of York Street. All three facades fronting onto sidewalks should be redesigned at sidewalk level to engage passersby and better animate the streets with retail, restaurants and better connections with the amenities of the building like the 'grotto'. No one is ever going to walk this stretch of Queen Street attracted by few restored pieces of concrete cladding and shiny, anonymous windows. It takes retail and restaurants to do that, and that's precisely the experience that people should be able to have at a place like across from Nathan Phillips Square.
