A quickie today: I don't have any great complaints about the architecture of the Mirabella, a recently completed high-rise "continuing care retirement community" in the South Waterfront. I'm not sure who wants to retire to a building adjacent to a working shipyard. And I think the heinous gray box at the buildings base was a misjudgment on the part of Ankrom Moisan, who designed the project with its developer, Pacific Retirement Services. It's a heavy weight on what is otherwise a graceful, winglike profile. But I must ask: The building has been finished for months now. Isn't it time to take off the masking tape?
