1144 Fifteenth Final Update

The time has come to wrap up our extensive update series on 1144 Fifteenth, Denver’s newest modern skyscraper. Over the past 3 years and 10 months, we covered this project from announcement, to ground-breaking, excavation, vertical progress, topping out, inside tours, and now the complete project. We have a record-breaking 26 updates on this project which can all be viewed by following the link below.

1144 Fifteenth Post History

The 617-foot, 40-story tower provides 640,000 square feet of office space and makes quite a statement on Denver’s skyline, changing it forever. The all-glass tower has many features and unique looks when viewed from all directions around Downtown Denver, which we will be exploring in this final update. First, we will start with looking at the tower from the west side of Downtown Denver.

From Highland and the Central Platte Valley, 1144 Fifteenth has a very slim profile with a notch running up the middle. This is where the exterior lighting climbs up the length of the building.

When moving to the south, still on the edge of Downtown Denver, the unique roof-line starts to make an appearance, along with the true width of the tower. The immense amount of glass is a remarkable addition to this corner of the skyline.

Let’s move in closer and explore the ground floor of 1144 Fifteenth. When looking at the tower from 14th and Lawrence Streets, there is a 12-story blank wall facing an open plot of land. Eventually, the second phase of the Four Seasons will be built here covering up the blank wall.

When along 15th Street, each corner of the ground level has a very open and inviting presence with the glass wall continuing down through the lobby and masonry accents spanning the full width of the building. There will also be ground-floor retail at the corner of 15th and Arapahoe.

The landscaping along 15th Street is complete with ample seating, trees, and unique street lamps.

Of course, when standing by the base of a tall, modern, glassy tower, you have to look up. Because of the building’s curve, 1144 Fifteenth completely disappears into the sky when looking at it up close.

Now, let’s explore the tower from the other side of Downtown, looking at it from the north. From this angle the roof-line has a much sharper slope but has the same overall width as the other side.

Given its proximity to the Four Seasons, 1144 Fifteenth almost completely covers its neighboring tower when viewing it from this side of Downtown Denver.

Welcome to the Downtown Denver skyline, 1144 Fifteenth…

…you are a great addition…

…to an already great city!

Before we wrap up this project for good, here are some bonus views taken at dusk from the 37th floor.

Congratulations to Hines, the developer, Pickard Chilton, the architect, Hensel Phelps, the general contractor, and the dozens of teams that provided the glass, steel, engineering, landscaping, and every other element that made this building possible!

    This is a fantastic final update for this skyline changing tower!

    What is the second phase of the Four Seasons?

    1144 basically introduced me to this website, I have enjoyed every minute of reading the updates to this tower. Sad to see this is the final update but so happy to see it all finished as well. It felt like an extremely short 3 years from ground breaking to the tower crane dropping. Congrats to everyone involved in the construction and everyone following the progress of this tower.

    Thanks for the updates all these years on this great and prominent addition to downtown! Somewhat sad to see such a large construction project come to an end on Denver Infill. Hopefully there’s another right around the corner.

    • Dan April 17, 2018 at 8:27 am

      Fingers crossed for Block 162, given the latest update…

      • Adam April 17, 2018 at 9:42 am

        And maybe Two Tabor as well. Imagine these two 30+ office towers going vertical at the same time.

          …ok let’s stop now before we jinx it 😉

    it’s sort of a visually disturbing structure, blocky with weird angles, though nice to have the extra square footage downtown

  6. Freddie April 17, 2018 at 10:16 am

    Great photography!

  7. Ryan April 17, 2018 at 10:40 am

    This is a spectacular building…great photos

  8. Tom Harper April 17, 2018 at 12:06 pm

    It’s a beautiful addition to the skyline and reveals a particularly nice effect as the sun sets. Great photos to cap it all off!

    Is 617 feet the official height? I used to see 603 used. But I’d take the extra 14 feet!

  10. Rob Gladwin April 17, 2018 at 4:38 pm

    I’m no architect, nor am I a developer, but I love looking at tall buildings. This is a beautiful addition to our skyline. Now, I was in Shanghai recently. Wow! Now that’s a skyline! I wish we could see more height here. Our downtown is vibrant, fun and honestly, quite safe and clean compared to many other cities. If the money is there, I think we should go for it.

    I agree with Landon. Couldn’t have said it better – blocky with weird angles. The top is especially weird. Hard to understand the programmatic requirements that resulted the odd mishmash of angles. And I don’t get the total disconnect of the first two floors with the rest of the building.

  12. Robert Clearwater April 17, 2018 at 11:12 pm

    The top of the tower, in an effort to be “different”, makes a weak design statement considering the scale of the building. A stronger statement would integrate with the sky and not look so blunt or truncated.

    • FL Wright April 26, 2018 at 3:35 pm

      the undulating crown pays homage to the rocky mountains! what other building in the Denver skyline respects it surrounding in this sense. integrate with the sky = flat top? meh

  13. sgsfghfg April 18, 2018 at 9:59 am

    Very slick building… just wish it was 10-15 stories higher 🙂

  14. JoBa April 18, 2018 at 3:35 pm

    Why are there small holes in the vertical metal strips that run up the entire building? Is it so wind can pass through?

    • FL Wright April 26, 2018 at 3:39 pm

      make-up air for each floor mechanical system

  15. Cherry Creek April 19, 2018 at 9:35 am

    I love the building. Architecturally, I think it’s the most important Denver skyscraper. This is because of the design which gives its such prominence from so many different directions and also gives very different looks, depending on the angle of view. Also, the complete glass siding allows it to play off the other buildings and the great Colorado sun.

    My top 5 are (1) 1144 (2) Four Seasons; (3) Republic Plaza; (4) Cash Register (Wells Fargo) and (5) Holy Ghost (1999 Broadway).

    Gorgeous building. And that view from The Coloradan! 🙂

  17. Ty May 7, 2018 at 10:38 am

    Does anyone know what the logo is on the building? It started going up last week, and I thought it was unfinished… but they haven’t added to it in several days so I’m wondering if that’s final. Any ideas? (p.s. it’s an UGLY logo if it’s final)

    • Ken Schroeppel May 7, 2018 at 11:59 am

      That is the logo for Optiv, the anchor tenant. https://www.optiv.com/

      • Ty May 8, 2018 at 4:19 pm

        thanks ken! after nearly a week, the rest is starting to go up. i did some detective work after my comment and read about the tenants. i appreciate the update to my easily searchable question haha
