1350 N Speer Blvd

1350 N Speer Blvd 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. 1350 N Speer Blvd 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. Its windowless core is hatched. The inset places it among every building the screen covers.

Typical floor plan: 77% of the building’s floor area sits within daylight reach of a facade; the drawing shows its typical floor, where the share is 96%. The shading is daylight, darkest at the windows and gone 35 ft in. The hatched area is windowless core: 3,279 sq ft per typical floor that must be renovated but can never be rented as an apartment. The dimension marks the deepest interior point, 48 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, fading as it goes, and the hatched stripe left between the lit edges is floor that gets converted and can never be rented: 3,279 sq ft on the floor the screen scores, and 111,771 sq ft over 6 residential floors. 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 is already an apartment building: Denver's property records list 322 apartments here. It is on the map because the city's building outlines file it as commercial, but this site does not count it as a conversion candidate.

Across its 6 residential floors this building carries 111,771 sq ft of windowless core — area that must be gutted, re-plumbed and sprinklered but can never be rented as an apartment.

The plan: window line, shape and floor rhythm

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

The typical floor has 2,224 ft of exterior wall, and across 6 residential floors the building carries 11,842 ft of it in total, divided among the 403 homes this screen estimates.

Its plate is highly articulated at 0.19: 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 67.2 homes per floor. Its floors are not alike, though: the typical floor's deepest interior point is 48 ft from a facade, while its worst floor reaches 124 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.
