NABB and BBAC are risk-averse entities controlled by elderly people trapped between dueling orthodoxies that together are rigidly stifling. The first, driven by an old-school interpretation of modernist tenets, dictates that anything faux historic or ornamental is verboten - that would be unacceptably "inauthentic." The second orthodoxy is that nevertheless that any new construction must "fit in." The tension between these orthodoxies dictates the most bland, insipid structures possible, and the BPDA and most project proponents are usually only too happy to oblige, presumably leaving the architects who proposed iterations 1-3 sobbing in their cubicles.
The various iterations of Druker's Shreve replacement went through a very similar cycle. Never mind the pending loss of the characterful buildings that are there, the render progression of the proposed development went from vaguely interesting to entirely lifeless, supposedly after "architect" consultant commentary.
The irony, of course, is that despite its strictly controlled scale, conservative palette, and the inevitable nod to "bay windows," a building like this doesn't actually fit in - it serves instead as a sad reminder of how much richer and livelier (and yes, ornamental) the original buildings further down the block are. And at the same time, this building does manage, despite itself, to be faux historic - not echoing its 1880s neighbors, of course, but rather its 1980s infill predecessors. The latest iteration here is essentially indistinguishable from Back Bay buildings from 1 to 40 years ago. It's as if time has stopped!
Surely there must be a handful of architects or urban design enthusiasts under 65 years old living in the Back Bay who could jolt some life into NABB? If you are going to insist on being "modern," what's wrong with a welcoming architectural gesture like the "A" entrance proposed in the first three iterations above? Otherwise, if you are going to insist on "fitting in," why not go full Prince Charles and re-create a building of 140 years ago? How about a thoughtful reconstruction of, say, the original S.S. Pierce building (1887-1958)? Either would be miles better than what we're going to get.
