They completely leased 250k of spec office over a year before completion, so I'm guessing they love the commercial market. Have they said anything about the timeline for Parcel I?
Lot I will be a residential building with green space (one iteration showed the approved structure with theater-in-a-round concepts) and retail. Tentative early plans suggest construction will begin there after Lot W is complete, which accompanies the completion of JK and the park's north end rebuild. (There are quite a few diagrams online for all of these.)
*Moderators*, you might want to consider opening a thread for Cambridge Crossing Parcel EF (not Education First), since DivCo West began driving sheeting for the bathtub for that structure last week. Our weekly S+T construction update confirmed that construction had commenced. There is City of Cambridge approved imagery online. I-93, the Gilmore Bridge, Zinc, and Route 28 northbound should provide Lot EF viewing locations (especially through the viewports through the CX wrapping at the old MBTA lot just before the Glassworks condo building.
@Tango recalls that the outer ring of buildings (including Lots A, B, C, D, EF, G, H, U, R, Q1, Q2, and the elusive V) was originally to have been a second phase of construction completed after the inner ring grew retail, parking, and green space to accommodate a larger development footprint (Lots I1, I2, I3, JK, L+M, N, T, S, and W). However, when we brought DivCo to the annual board meeting, they affirmed they are adamant about pursuing growth opportunistically, which is why we've seen a push for EF, W, R, I1-3, G, and H.
