Well, the 68 Smithe PDF document says "A rezoning application for Area 6b (Plaza of Nations, owned by Canadian Metropolitan Properties) was submitted in June 2012 and is in process." 6b is the location of the Arch building pointed out by dleung.
However, in the 750 Pacific Blvd thread there is a
message from user Trocadero saying, "I was at a public meeting of False Creek residents a few weeks ago where the developer (Canadian Metropolitan Properties) announced that the whole project was dead. Perhaps developers make announcements like this often while negotiating with the City, but it seemed sincere. He said that the Aquilinis and his owners were prepared to let it all sit, as is, for as long as necessary."
So maybe you don't have to worry about your window issue. For now at least.
