This is why only developers who are fools would build tall in Kendall:
50 Binney was just sub-leased for $100 a square foot (actually a nickel shy of $100 at $99.95) by Sanofi to Bluebird. Sanofi's lease with Alexandria is $62.50 a square foot. Sanofi is making $27.45 a square foot with its sub-lease flip.

But would that also pertain to residential in Kendall?
