It's interesting, I wonder what Pinnacle's plan is here.
I'm guessing their reasoning behind building the shortest tower first is that it has the largest podium (and therefore stores/community centre/etc), and therefore the area will be more attractive to purchasers when phases 2 (the big momma) and phase 3 launch. In that sense, I suppose they're content with starting phase 1 before selling out, because really it's about developing the area for phases 2 and 3 (which might also explain why they're selling phase 1 at $1200+/sqft, which seems high, but they can sell it at a high price if they don't need the money ASAP). If that's the case, I'm kind of surprised they're not building the commercial portion of this development (the south lot) ASAP as well. Seems like it'd be relatively easy (in that it wouldn't interfere much with the construction of the condos) and yet would allow the area to become more developed.
Anyways, just some thoughts. Excited to see this development go up, wish it could all be done with the snap of a finger!
