The plan: window line, shape and floor rhythm
34 ft of exterior wall for each home the screen estimates — enough for two- and three-bedroom homes across the plan.
The typical floor has 1,609 ft of exterior wall, and across 6 residential floors the building carries 8,849 ft of it in total, divided among the 257 homes this screen estimates.
Its plate is highly articulated at 0.21: a long, notched or wing-shaped outline with far more facade than its area needs — wasteful as an office envelope, and close to ideal for apartments. How window line and plate shape are measured.
At the model’s 750 sq ft average, the plan works out at about 42.8 homes per floor. Its floors are not alike, though: the typical floor's deepest interior point is 42 ft from a facade, while its worst floor reaches 67 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 47 out of 100: remaining gap is 32% of conversion cost, scored from 60% down to 0%.
What the conversion would cost
$360 per square foot all-in across 286,906 sq ft of converted floor, or $103.3M in total — about $402K for each of the 257 homes.
All-in cost per square foot for 2401 Blake 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 45,395 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 257 homes is $60.7M.
What would have to be true
A $42.6M gap before any grant, $32.6M after the modeled one. The smallest single change that would close it: average unit size 35% down.
The shortfall before any grant is $42.6M. Closing it from the value side means each of the 257 homes finishing at $402K rather than the $236K the model assumes — 70% more. Closing it from the cost side means getting all-in cost down from $360 to $211 per square foot.
A modeled RESIDE grant of $10.0M moves that threshold to $363K a home. That is still above the $236K assumed, leaving $32.6M uncovered, which is why the grant does not unlock this one.
Nor do all four levers have to move. For 2401 Blake St, one alone would close the gap at:

Within Five Points
3rd of 20 in Five Points — the comparison that shares its rules, rents and streets.
Denver places 20 of the screened buildings in Five Points. 2401 Blake St ranks 3rd of them against a median score of 68. 9 score 70 or more, their median deepest interior point is 61 ft from a facade against this building’s 42 ft, and together they would hold an estimated 5,122 homes. The group’s top scorer is 3355 Denargo St, at 90.
Its nearest match in size: 1960 N Ogden St
The screened building closest to 2401 Blake St in converted floor area is 1960 N Ogden St: 291,388 sq ft over 8 stories, against 286,906 sq ft over 7 here.
2401 Blake St scores 86 to its 70, and with the size held roughly equal most of that lead comes from interior depth: 95 out of 100 here, 54 there (deepest interior point 58 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 6,000 ft apart.
Would it qualify for a RESIDE Act grant?
The model awards 2401 Blake 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.
