I'll take a shot ... at least in part.
This building could be 75% better without even fiddling with the massing, height, or overall size, and simply devoting a tiny bit of attention to materials, palette, and surface articulation.
This essentially looks like a Home Depot that has been pitched up twenty stories. Similar cheap-looking puke colored panels, the same flatness, similar two-tone scheme. In fairness to Home Depot, the panels used in their big box DIY centers seem less mottled and have better color match, so the two-tone beigeish contrast comes off more cleanly and clearly. Also, many Home Depots offer an attempt at a cornice, and their corporate orange provides a better/stronger contrast to the two-tone beige/puke, creating some visual interest. Indeed, if you took this dorm and added a couple of orange stripes and three windowless stories with big Home Depot signage on top, capped by a faux cornice, it would complete the strip mall aesthetic and give the architects on the board something to talk about ... instead of "Learning from Las Vegas" we could demonstrate "Learning from Jacksonville." In my view, this would be an improvement, and I'm not being (entirely) tongue in cheek. Can we at least add an orange stripe on top?
Failing that, would that they had given a bit of three-dimensionality to the windows, made at least some attempt to define the roofline and given a moment's actual thought into the color scheme ... would have worked wonders. With respect to the latter, if the goal was to keep it cheap but blend into the background, a palette more grey and less Home Depot would have been far better ... although as we have seen down the street, bold colors and a bit of imagination with shapes and surfaces can lend a precast-panel building quite a bit of interest and dynamism.
Of course, in an ideal world, you could make the building even better by fussing with the massing, perhaps adding some set-backs, trading a bit of height for shape and creating more of a "backdrop" for the Y in the sense that the Hancock provides a "backdrop" for the old Hancock. But that would have cost real money to pull off. What really pisses me off about this building is that the modest improvements I sketch out above, while not costless, couldn't possibly add more than what ... 2 or 3% to the cost of a building of this size? This looks like it was thrown up by a team that just didn't care.
It's ironic that in the '90s we marveled at how fresh and wonderful the Northeastern developments were compared to what was being constructed at Harvard, BU, and BC ... fast forward twenty years and while Northeastern (in this case, with a commercial partner-in-crime) has gone steadily in reverse, better architecture is demonstrated up further down Huntington Avenue by Mass Pharma, Wentworth, and (especially) MassArt. It's as if there is a negative correlation with institutional prestige.
