750 15th St

Where 750 15th St is

Its block in Greater Downtown Denver, drawn from Denver's own building outlines and street centerlines.

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 549 ft of exterior wall, and across 19 residential floors the building carries 10,301 ft of it in total, divided among the 251 homes this screen estimates.

Its plate is moderately compact at 0.50: 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 13.2 homes per floor. Its floors are not alike, though: the typical floor's deepest interior point is 32 ft from a facade, while its worst floor reaches 62 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.

Why 750 15th St scores 94 out of 100

Daylight efficiency 100, Interior depth 100, Scale 100, Finance 58 — each out of 100, then weighted.

Most of what it earns comes from daylight efficiency, and what holds it back most is finance, at 58 out of 100: remaining gap is 25% of conversion cost, scored from 60% down to 0%.

What the conversion would cost

$360 per square foot all-in across 257,926 sq ft of converted floor, or $92.9M in total — about $370K for each of the 251 homes.

That cost is charged across every converted square foot, including the 22,516 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 251 homes is $59.2M.

What would have to be true

A $33.6M gap before any grant, $23.6M after the modeled one. The smallest single change that would close it: average unit size 29% down.

The shortfall before any grant is $33.6M. Closing it from the value side means each of the 251 homes finishing at $370K rather than the $236K the model assumes — 57% more. Closing it from the cost side means getting all-in cost down from $360 to $230 per square foot.

A modeled RESIDE grant of $10.0M moves that threshold to $330K a home. That is still above the $236K assumed, leaving $23.6M uncovered, which is why the grant does not unlock this one.

Nor do all four levers have to move. For 750 15th St, one alone would close the gap at:

How it compares in Greater Downtown Denver

750 15th St ranks 13th of the 214 buildings screened here, against a median score of 72.

Its floor plate is better lit than 79% of them, and shallower than 93% of them at its deepest interior point. On size it is the 88th largest by estimated homes. The full survey of all 214 buildings ranks and maps every one of them, and the list by address links each to its own page.

Within CBD and the D-C zone

8th of 75 in CBD, 5th of 72 zoned D-C — the comparison that shares its rules, rents and streets.

Denver places 75 of the screened buildings in CBD. 750 15th St ranks 8th of them against a median score of 71. 40 score 70 or more, their median deepest interior point is 56 ft from a facade against this building’s 32 ft, and together they would hold an estimated 33,698 homes. The group’s top scorer is 918 17th St, at 97.

72 of the screened buildings are zoned D-C. 750 15th St ranks 5th of them against a median score of 73. 39 score 70 or more, their median deepest interior point is 57 ft from a facade against this building’s 32 ft, and together they would hold an estimated 32,881 homes. The group’s top scorer is 721 19th St, at 95.

Its nearest match in size: 1801 N Broadway

The screened building closest to 750 15th St in converted floor area is 1801 N Broadway: 258,252 sq ft over 20 stories, against 257,926 sq ft over 20 here.

750 15th St scores 94 to its 77, and with the size held roughly equal most of that lead comes from interior depth: 100 out of 100 here, 59 there (deepest interior point 56 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 1,800 ft apart.

Would it qualify for a RESIDE Act grant?

The model awards 750 15th 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.
