As mentioned in our previous post, Hines will be breaking ground on 1144 Fifteenth Street on Tuesday, June 9. For this post, we’re happy to provide you with a comprehensive description of the tower and its many design elements and amenities, plus a bunch of final design renderings, all courtesy of Hines.
Let’s start with out with a bang: Denver, here’s your newest skyscraper!
1144 Fifteenth will rise 603 feet, putting it about 40 feet taller than the top floor of the Four Seasons but about 35 feet lower than the tip of the Four Seasons’ spire, making it Denver’s fourth or fifth tallest tower, depending on if you want to count the Four Seasons’ spire or not.
The tower will have 40 floors topped by two mechanical levels for a total of 42 floors above grade, and two levels below grade. Here’s a breakdown of how the floors stack up:
Underground levels P2 and P1: Parking
Ground floor: Lobby and two retail spaces
Floor 2: Gym/fitness center with locker rooms (5,500 SF) and a Living Room gathering space (2,500 SF)
Floors 3-13: Parking
Floors 14-40: Office
Floors 41-42: Mechanical
The building will have 657,400 square feet of office space and 5,500 square feet of retail for a total of 662,900 square feet (excluding parking). The average office floor plate size is 24,900 square feet.
Let’s take a closer look at the different building areas and elements:
Ground floor: The lobby will include three elevator banks (high-rise, low-rise, and garage) as well as a grand staircase that leads to the Living Room space and gym/fitness center on Floor 2. The elevators will be of the “destination dispatch” type. The ground floor also includes typical back-of-house functions and three loading dock stalls. The main pedestrian entry will be at the corner of 15th and Arapahoe. The garage entrance will be on Lawrence Street and the garage exit on Arapahoe. The lobby will have Italian marble floors and aspen ceilings and millwork to complement orange architectural glass and stainless steel accents.
Floor 2: The Living Room space on Floor 2 allows for tenants and guests to collaborate and socialize in a living room-style setting with library tables, a fireplace, couches and chairs, TVs, and a great view overlooking Skyline Park.
Parking: There will be a total of 840 vehicle parking spaces, including 10 electric car charging stations, as well as bike racks and 47 lockable bike storage lockers. One of the parking levels will also include a full-service car wash. The 840 parking spaces results in a parking ratio of 1.27 spaces per 1,000 SF of space, which is fairly low. For comparison purposes, the parking ratio of Hines’ other downtown project under development, 1601 Wewatta, is 1.35 spaces per 1,000 SF. A new 16-story office project that broke ground on Tuesday in the Denver Tech Center called One Belleview Station, which bills itself as a “transit-oriented development,” has a parking ratio of 3.50 spaces per 1,000 SF.
Floor 14: The fourteenth floor, the first level with office space, includes a conference facility with 15-foot ceilings and a large terrace overlooking Arapahoe Street and the Downtown skyline.
Plaza: The building’s plaza along 15th Street will include a black granite pyramid-shaped art installation that will reflect the building image. The retail space on the Arapahoe side will have an elevated patio.
Floor 40 and building crown: The top office level, Floor 40, will include two small terraces, one facing the city, the other facing the mountains. The crown incorporates multiple angled glass panels that resemble mountain peaks to enclose the two mechanical penthouse floors.
Nighttime illumination: The tower’s nighttime illumination scheme will feature a continuous LED white-light strip located in both corners of the tower’s two notched spines, running vertically from the tower base to the crown. This new-to-Denver lighting system will accentuate the building’s verticality and give the tower a stunning but dignified presence in the evening skyline.
Glass curtain wall: The tower’s glass will be high energy efficient and low reflective with a blueish hue, and 5-inch architectural fins articulating from the building with two strips per floor.
The project has been pre-certified LEED Gold for the core and shell.
