No need to undersell it, BeeLine. LOL
What was also new, to me, was that they would be demolishing 250 Binney St and replace it with an 85 foot deep underground garage and a second 250' (?) commercial building.
Keep in mind that 250' height limit covering most of Kendall typically results in towers around 280'-295', including the Marriott, first MXD, Ames residential, giant lab across from Ames residential, Boeing MIT building, and that MIT building currently being clad with the beige cladding and double height windows. If the strict limit was inclusive of the mech tops, all these buildings would have been 30-50' shorter than their actual heights.
Confirmed that the 400' does not include mechanical. A new application amendment just posted to the planning board site. This is going to planning board review on 9/28.
