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!
