300 E 17th Ave

300 E 17th Ave and the 1,000 ft of Greater Downtown Denver around it. The streets are drawn at the width of the right-of-way they run down, sidewalks included, and named, and every building on these blocks is drawn. What is left open and stippled is neither: a surface lot, a plaza or a vacant parcel. The screened buildings are colored by the ramp above, the same one the district map uses, carry their score, and each is a link to its own page. Each casts a shadow as long as its measured height lets it, so towers stand out from the low buildings around them; the unscreened buildings have no measured height and cast none. 300 E 17th Ave is outlined in its own score color at the outline it covers at ground level. Dashed inside it is the typical floor, the one the floor-plate figure below draws, because this building steps back as it rises. The inset places it among every building the screen covers.

Typical floor plan: 100% of the building’s floor area sits within daylight reach of a facade; the drawing shows its typical floor, where the share is 100%, with no dead core at all. The shading is daylight, darkest at the windows and gone 35 ft in. The dimension marks the deepest interior point, 35 ft from the nearest window. A–A is where the section beside it is cut.

Section A–A: cut across the depth of the plate, through the middle of the core. Daylight reaches 35 ft in from every facade, and here it meets in the middle: the plate is thin enough that no floor is left windowless. The steps are where the building sets back as it rises. The shaded ground floor is converted like the rest and counted as no homes.

This building does not pencil at default assumptions, even with a modeled RESIDE Act grant.

This footprint has no windowless core at all: every point on the floor plate is within 35 ft of a facade, which is unusual and is the main reason it scores as well as it does.

The plan: window line, shape and floor rhythm

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

The typical floor has 919 ft of exterior wall, and across 11 residential floors the building carries 10,141 ft of it in total, divided among the 224 homes this screen estimates.

Its plate is elongated at 0.29: 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 20.4 homes per floor, repeated on every residential floor, since this building's outline does not change as it rises.

Why 300 E 17th Ave scores 96 out of 100

Daylight efficiency 100, Interior depth 100, Scale 100, Finance 72 — each out of 100, then weighted.

Score components for 300 E 17th Ave. Points are the subscore times its weight.

Most of what it earns comes from daylight efficiency, and what holds it back most is finance, at 72 out of 100: remaining gap is 17% of conversion cost, scored from 60% down to 0%.

What the conversion would cost

$360 per square foot all-in across 210,568 sq ft of converted floor, or $75.8M in total — about $338K for each of the 224 homes.

All-in cost per square foot for 300 E 17th Ave: 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 circulation and service area that earns nothing directly. Against it the model sets a completed value of $236K a home, which for 224 homes is $52.9M.

What would have to be true

A $22.9M gap before any grant, $12.9M after the modeled one. The smallest single change that would close it: average unit size 19% down.

The shortfall before any grant is $22.9M. Closing it from the value side means each of the 224 homes finishing at $338K rather than the $236K the model assumes — 43% more. Closing it from the cost side means getting all-in cost down from $360 to $251 per square foot.

A modeled RESIDE grant of $10.0M moves that threshold to $294K a home. That is still above the $236K assumed, leaving $12.9M uncovered, which is why the grant does not unlock this one.

Nor do all four levers have to move. For 300 E 17th Ave, one alone would close the gap at:

How it compares in Greater Downtown Denver

300 E 17th Ave ranks 4th of the 208 buildings screened here, against a median score of 73.

Its floor plate is better lit than 93% of them, and shallower than 88% of them at its deepest interior point. On size it is the 100th largest by estimated homes. The full survey of all 208 buildings ranks and maps every one of them, and the list by address links each to its own page.

Within North Capitol Hill and the PUD zone

2nd of 41 in North Capitol Hill, 1st of 21 zoned PUD — the comparison that shares its rules, rents and streets.

Denver places 41 of the screened buildings in North Capitol Hill. 300 E 17th Ave ranks 2nd of them against a median score of 85. 32 score 70 or more, their median deepest interior point is 47 ft from a facade against this building’s 35 ft, and together they would hold an estimated 8,820 homes. The group’s top scorer is 1776 N Grant St, at 97.

21 of the screened buildings are zoned PUD. 300 E 17th Ave ranks 1st of them against a median score of 77, the top score in the group. 12 score 70 or more, their median deepest interior point is 49 ft from a facade against this building’s 35 ft, and together they would hold an estimated 5,808 homes.

Its nearest match in size: 1441 18th St

The screened building closest to 300 E 17th Ave in converted floor area is 1441 18th St: 212,860 sq ft over 12 stories, against 210,568 sq ft over 12 here.

300 E 17th Ave scores 96 to its 78, and with the size held roughly equal most of that lead comes from interior depth: 100 out of 100 here, 44 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 5,100 ft apart.

Would it qualify for a RESIDE Act grant?

The model awards 300 E 17th Ave $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.
