Verdict

Density binds before height: FSR caps you at 54,450 sf, reachable in 5 of the 125 permitted storeys, so 1,442,925 sf of height envelope sits unused.

03Questions

Frequently asked

Why does parking displace GFA?

Structured parking usually sits inside the measured building volume, so every stall consumes gross area that could have been saleable. Where a bylaw excludes below-grade parking from GFA the cost stays but the area does not — set the stall area to zero to model that case.

What is a realistic cost per stall?

It varies by structure type and market, which is why nothing is pre-filled as fact here: surface, above-grade structured and underground stalls differ by an order of magnitude. Use your own quantity surveyor's number.
