Pemberton is more than capable of not cheaping out and doing a good job, BUT ONLY if you overpay them significantly. If I'm not mistaken, U condo was charged 800-900/sqft initially (when every other condo was going around 400-500/sqft downtown back then).
Currently living in another Pemberton's building (Social) and I can without a doubt tell you the corner is cut everywhere I can see and can't see. In addition to the sub-par craftsmanship inside the unit, I can hear my upstairs neighbor walking/dropping stuff/partying, fire alarms, flooding, rusty pipe, hot water issue etc. The list goes on and on.
As in the case of 33 Yorkville here, you are looking at ~2k/sqft which is almost double the current average DT market price, so I don't doubt that the buyers will get a relatively high quality product in this case. They know not to mess around with their rich clients.
