Solid concrete tower so I don't think noise will be a huge factor (barring really loud music or what have you). It is actually surprisingly quiet when you close everything up (window and patio). Can't even hear the SkyTrain or traffic.
And yes lol the sink kind of does look like that.
As for renters, _ALL_ renters have to go through the rental management company from my understanding which requires them to be screened. Obviously you can't be 100% sure but I believe they are pushing really hard to make sure there aren't major issues with rental units in the building. The odds are higher unfortunately since there are over 700 units but I'm not worried. It's part of life and will deal with it when and if I have to deal with it.
I didn't take any pictures of the commercial building unfortunately. I may when I get back from vacation in a few weeks but they are looking great. The portion facing the towers (away from skytrain) is pretty much completed. Looks to me like they are just doing finishing touches. Stairs are all done with just some landscaping.
Also the inner court yard is pretty much all completed that's where I parked and the retail units (1 to 6) are at the base of the 2 towers facing inside teh court yard. They don't front Whalley Blvd or 100th obviously but it makes a nice little community space.
So when done there will be 6 retail units under the 2 towers and then the commercial building on the other side. There will also be retail at the base of the next phase of that block which according to Concord right now will be Phase 2 of Park Avenue, Phase 1 being the old Sky Towers development.
