I believe the Edward is 5s.
I don't think it's a bad thing to have townhouses, low rises, and SFHs all mixed together for the next 50 years. A diversity of housing stock is good for the neighbourhood. I agree it would be good to develop the main streets in order to provide sufficient amenities within walking distance, but that's a chicken and egg problem. You need the density to support the amenities and vice versa. Hopefully a project like this will spur more mixed-use development along 14 Street and even 26 Ave. In the meantime, this building is only a couple minutes walk to a bus stop on 26 ave, 10 minutes walk to the heart of the Marda Loop commercial district, and a 15 minute bike downtown. And it's literally around the corner from CSpace.
