1701 John F Kennedy Blvd

Where 1701 John F Kennedy Blvd is

Its block in Center City Philadelphia, drawn from Philadelphia's own building outlines and street centerlines.

The plan: window line, shape and floor rhythm

40 ft of exterior wall for each home the screen estimates — enough for two- and three-bedroom homes across the plan.

The typical floor has 1,316 ft of exterior wall, and across 57 residential floors the building carries 75,021 ft of it in total, divided among the 1,885 homes this screen estimates.

Its plate is elongated at 0.35: a slab or an L, which is why so much of the floor lies within reach of a window: the outline buys daylight that a square plan of the same area would not. How window line and plate shape are measured.

At the model’s 750 sq ft average, the plan works out at about 33.1 homes per floor, repeated on every residential floor, since this building's outline does not change as it rises.

Why 1701 John F Kennedy Blvd scores 35 out of 100

The weighted components add to 36, but the score is capped at 35 because its deepest interior point is 95 ft from a facade, past the 80 ft threshold beyond which conversion requires carving a light well.

Most of what it earns comes from daylight efficiency, and what holds it back most is interior depth, at 0 out of 100: deepest interior point 95 ft from a facade, scored from 80 ft down to 40 ft.

Built in 2007

Philadelphia records this building as going up in 2007, which puts it in the modern stock.

As a rule, newer systems and better structure, but usually built deep and sealed for office use, and rarely cheap enough to buy at a price that lets a conversion pencil. That is the era’s general tendency rather than a finding about this building — the model reads an outline and a height, and can see nothing inside — but it is the first thing an architect would want to know, and it colours how much confidence the 64% daylight figure above deserves.

What the conversion would cost

$360 per square foot all-in across 2,783,552 sq ft of converted floor, or $1.00B in total — about $532K for each of the 1,885 homes.

That cost is charged across every converted square foot, including the 1,015,468 sq ft of windowless core, which has to be gutted, re-plumbed and sprinklered like the rest of the building and then earns nothing. Against it the model sets a completed value of $197K a home, which for 1,885 homes is $370.8M.

What would have to be true

A $631.3M gap before any grant, $621.3M after the modeled one. The smallest single change that would close it: average unit size 63% down.

The shortfall before any grant is $631.3M. Closing it from the value side means each of the 1,885 homes finishing at $532K rather than the $197K the model assumes — 170% more. Closing it from the cost side means getting all-in cost down from $360 to $133 per square foot.

A modeled RESIDE grant of $10.0M moves that threshold to $526K a home. That is still above the $197K assumed, leaving $621.3M uncovered, which is why the grant does not unlock this one.

Nor do all four levers have to move. For 1701 John F Kennedy Blvd, one alone would close the gap at:

How it compares in Center City Philadelphia

1701 John F Kennedy Blvd ranks 82nd of the 103 buildings screened here, against a median score of 67.

Its floor plate is better lit than 23% of them, and shallower than 8% of them at its deepest interior point. On size it is the largest by estimated homes. The full survey of all 103 buildings ranks and maps every one of them, and the list by address links each to its own page.

Within the CMX5 zone

50th of 65 zoned CMX5 — the comparison that shares its rules, rents and streets.

65 of the screened buildings are zoned CMX5. 1701 John F Kennedy Blvd ranks 50th of them against a median score of 67. 28 score 70 or more, their median deepest interior point is 58 ft from a facade against this building’s 95 ft, and together they would hold an estimated 30,650 homes. The group’s top scorer is 112 N Broad St, at 93.

Its nearest match in size: 1650 Market St

The screened building closest to 1701 John F Kennedy Blvd in converted floor area is 1650 Market St: 2,155,597 sq ft over 61 stories, against 2,783,552 sq ft over 58 here.

The two land within a few points of each other — 35 here, 35 there — so at this size the screen reads them as much the same prospect. On the money they sit in the same place: each falls short even with the modeled grant. The two stand about 800 ft apart.

Would it qualify for a RESIDE Act grant?

The model awards 1701 John F Kennedy Blvd $10.0M, on the assumption it qualifies. Whether it does, no published dataset can say.

That figure assumes the building meets the Act’s vacant-and-abandoned test, which turns on code-enforcement and receivership records no city publishes.

It does not sit in a 2018 designated Opportunity Zone, so it would not draw that Section 201 priority.
