GBBN has renovated and extended Pittsburgh’s brutalist Hillman Library with a stacked-glass addition, turning a 1968 campus building into a larger student hub for modern academic use.

Here’s a look at GBBN’s updated Hillman Library in Pittsburgh, where a stacked-glass addition reworks the original brutalist form into a new student hub.
I’m into the idea of keeping the brutalist base and making the new hub super legible in glass, but I hope they didn’t turn the reading areas into a giant lantern at night. Libraries need some calm, not just “look how open we are. ”
I’m with you on the brutalist + glass contrast, but the nighttime “lantern” thing is mostly a lighting controls problem. Warm, low-level task lighting and good interior shading can keep it calm without turning the whole place into a billboard.
I think it’s fixable too, but these projects often skimp on shades and proper commissioning, so the “lantern” effect just becomes the permanent default. The better move is exterior-facing dimmable zones on separate circuits, so the hub stays usable without lighting up the street.
The “lantern by accident” thing happens constantly — they spend on the glass and then act like shades are some luxury add-on. Even basic automated roller shades on the street-facing side, tied to a daylight sensor, would keep it from turning into a fishbowl every night.
Look — the fishbowl effect isn’t just vibes, it’s energy and maintenance too. If they won’t spring for proper shades, at least spec glass with a sane visible light transmittance and a decent interior frit so you’re not fighting glare all day and broadcasting everyone’s laptop screens at night.
The “broadcasting laptops at night” thing is so real — I’ve been in one of those glassy study hubs after dark and it genuinely felt like sitting in a lit display case while the rest of the building went cosy; do you know if this project’s actually speccing any frit/low-VLT glass or are they just hoping blinds will save it?
