With a hat tip to this tweet from John Ricco, linking to this compendium of tall buildings in Center City Philadelphia from the Philadelphia City Planning Commission. The document provides a brief profile of each building, showing building height, site size, gross floor area, floor area ratio, year of completion, and floor count.

Cass Gilbert famously defined a skyscraper as “a machine that makes the land pay,” the kind of structure justified (and often required) by high land values. Gilbert’s distillation of the logic behind these buildings is inherently economic (hat tip to Kazys Varnelis):
Speaking of such enterprises

The more things change, the more they remain the same.
DC is nearing the end of a lengthy process to re-write the city’s zoning code. The re-write is mostly a reorganization, combining overlays and base zones in an effort to rationalize a text that’s been edited constantly over the better part of half a century.

One of the books I picked up through the rounds of exchanging holiday gifts is Vishaan Chakrabarti’s A Country of Cities: A Manifesto for an Urban America. I’ve read an excerpt of the book published in Design Observer and watched Chakrabarti’s accompanying lecture; I’m looking forward

The latest state-level population estimates show another year of 2%+ growth for DC, bringing the city’s estimated population to 646,449. Former Mayor Tony Williams set a goal in 2003 of adding 100,000 new residents to the city back when the city’s population growth was essentially nil, following decades

While visiting Europe, I missed most of the local debate on potential changes to DC’s federally imposed height limit (see – and contrast – the final recommendations from the NCPC and DC Office of Planning, as well as background materials and visual modelling, here). But I sure didn’t actually miss any tall buildings; I saw

One dynamic that comes up in DC’s height limit debates is the tension between gains and losses, impacts on the city and benefits to it. New development can clearly add value, but the question is if that value is a mere ‘give-away to developers’ or if citizens

Continuing on the discussion of DC’s height limit (and potential changes to it), I wanted to take note of a few more articles on the subject. George Mason law professor David Schleicher (he of land-use law and procedure fame) asks height limit proponents six basic questions, all

Following up on some of the trade-offs mentioned at the end of the previous post on DC’s height act.
In the discussion of Kaid Benfield’s piece supporting DC’s height limit, several comments are worth highlighting. First, Payton Chung notes the need to discuss more than just supply, but

DC’s lack of tall buildings is certainly one of it’s defining characteristics. Given our human tendencies to be loss averse, to embrace the status quo, it shouldn’t be a surprise that changing such a characteristic can be shocking to some.
I’ve written on the height limit before,
