The plan: window line, shape and floor rhythm
41 ft of exterior wall for each home the screen estimates — enough for two- and three-bedroom homes across the plan.
The typical floor has 427 ft of exterior wall, and across 31 residential floors the building carries 15,057 ft of it in total, divided among the 368 homes this screen estimates.
Its plate is moderately compact at 0.69: a squarish plan, with enough perimeter for a conventional double-loaded corridor. How window line and plate shape are measured.
At the model’s 750 sq ft average, the plan works out at about 11.9 homes per floor. Its floors are not alike, though: the typical floor's deepest interior point is 41 ft from a facade, while its worst floor reaches 50 ft. The score follows the typical floor, so a podium that could not hold a bedroom does not by itself sink a slim tower above it — but it is there, and it is part of what would have to be drawn around.

Most of what it earns comes from daylight efficiency, and what holds it back most is finance, at 57 out of 100: remaining gap is 26% of conversion cost, scored from 60% down to 0%.
What the conversion would cost
$360 per square foot all-in across 361,322 sq ft of converted floor, or $130.1M in total — about $353K for each of the 368 homes.
All-in cost per square foot for 1441 Little Raven St: base cost plus the code work a change of use triggers.
| Base conversion cost | $260/sq ft |
|---|---|
| Plumbing risers to every unit | $40/sq ft |
| Operable windows and glazing | $30/sq ft |
| Additional egress stair | $18/sq ft |
| Fire sprinklers (NFPA 13R) | $12/sq ft |
| All-in | $360/sq ft |
That cost is charged across every converted square foot, including the 15,906 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 $236K a home, which for 368 homes is $86.8M.
What would have to be true
A $43.2M gap before any grant, $33.2M after the modeled one. The smallest single change that would close it: average unit size 28% down.
The shortfall before any grant is $43.2M. Closing it from the value side means each of the 368 homes finishing at $353K rather than the $236K the model assumes — 50% more. Closing it from the cost side means getting all-in cost down from $360 to $240 per square foot.
A modeled RESIDE grant of $10.0M moves that threshold to $326K a home. That is still above the $236K assumed, leaving $33.2M uncovered, which is why the grant does not unlock this one.
Nor do all four levers have to move. For 1441 Little Raven St, one alone would close the gap at:

Its nearest match in size: 1675 N Broadway
The screened building closest to 1441 Little Raven St in converted floor area is 1675 N Broadway: 390,581 sq ft over 30 stories, against 361,322 sq ft over 32 here.
1441 Little Raven St scores 93 to its 68, and with the size held roughly equal most of that lead comes from interior depth: 97 out of 100 here, 46 there (deepest interior point 62 ft from a facade, scored from 80 ft down to 40 ft). On the money they sit in the same place: each falls short even with the modeled grant. The two stand about 6,800 ft apart.
Would it qualify for a RESIDE Act grant?
The model awards 1441 Little Raven St $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.
