Central Downtown: 1144 Fifteenth Update #8

For this update of 1144 Fifteenth, the 40-story office tower Hines is building at 15th and Arapahoe, let’s go way above the site and take a peek down into the construction pit where the underground parking and the core of the structure are going in. For more about the building’s foundation, check out Ryan’s Update #7 post. A big THANK YOU to DenverInfill reader S. Autrey for  the photos!

These photos also give us a bird’s-eye view of little stretches of the new Arapahoe and Lawrence street protected bike lanes. With 15th Street also having a protected bike lane, 1144 Fifteenth will be surrounded by some of the best bicycle infrastructure in Downtown Denver!



We’ll check in at 1144 Fifteenth when the building begins climbing above ground level.

Central Downtown: 1401 Lawrence Update #9

Swinging back over to central Downtown Denver, let’s check in on the quickly rising 1401 Lawrence. The last milestone was when the parking structure topped out with the first floor of the office portion starting to rise.

The low winter sun is upon us, casting long shadows while highlighting the tops of buildings in a brilliant, golden glow. Rising up 14-stories, 1401 Lawrence is starting to make its mark on the Denver skyline.

Even with eight more stories to go, this project has a huge impact next to Larimer Square; helping create a frame for one of Downtown’s most popular destinations.

Looking down 14th Street from the Four Seasons, 1401 Lawrence is already positively changing the street level. It’s only going to get better from here as the project continues to rise along with the facade.

In the coming weeks, we should start to see the glass curtain wall rise on the upper portion of the office building, which will be featured in our next update. See you then!

Central Downtown: Le Meridien/AC Hotel Update #1

Yet another tower is under construction in Downtown Denver!

Recently, the dual-brand Le Meridien/AC Hotel project at the corner of 15th and California broke ground. Developed by White Lodging (which built the nearby Embassy Suites and is wrapping up the dual-brand Hyatt), this project will rise 20 stories and include 488 hotel rooms in total, split 272 rooms under the Le Meridien brand and 216 under the AC Hotel brand. Click here to see our first post on this project earlier this year.

As you can see in these photos I took yesterday, work is underway:



Here are the only renderings of the project I’ve seen released so far:



I think the building looks fairly decent from this angle. However, don’t be surprised if the angle you can’t see—the side facing 14th Street and the convention center—is a solid blank wall. While I don’t know this for a fact, it’s an educated guess. As the close-up rendering shows, the new Le Meridien/AC Hotel tower will share a common wall with the small two-story structure where Bubba Gump’s is located, which is also visible on the right side of my second construction photo. The Bubba Gump’s building is neither a designated historic landmark structure nor a member of the Downtown Denver Historic District; therefore, it could be razed someday to make way for a higher-density development. If that were to happen and White Lodging had put windows on that side of their hotel, those windows could potentially be completely blocked by a new development next door, since there are no setback requirements in the Downtown Core District for the side interior property lines. Any hotel rooms that had their only window subsequently blocked by a new adjacent development could be rendered uninhabitable as Colorado regulations require every hotel room have “at least one window with direct and unobstructed opening to the outside.” A developer putting in a hotel or residential building with a vacant or underutilized property on an adjoining site is unlikely to risk having that happen. Consequently, there are several design options frequently used to address this issue.

Option 1 is the solid blank wall. White Lodging chose this option on their new dual-brand Hyatt Place/Hyatt House hotel at 14th and Glenarm (which opens this December). Here are two images that illustrate this condition. In the first image (from Google street view) we see the blank wall facing the side property line. The small two-story building adjacent to the hotel is not a designated historic landmark structure or a member of the Downtown Denver Historic District, so it and the tiny parking lot next door could be redeveloped. Interestingly, the small two-story building on the right is the Denver Press Club building which is a Denver historic landmark building. Assuming it would not be razed, the redevelopment site adjacent to the hotel would be only 50 feet wide, which is quite narrow to go vertical to any significant degree.

In the second image (from Ryan’s recent Hyatt post) we see the same blank wall but from the alley view. Note that both images show that the hotel rooms on this side of the tower are served by windows facing Glenarm and the alley, eliminating the need for any windows facing the side property line.



Option 2 is the blank wall with fake windows. White Lodging used this approach in their Embassy Suites Convention Center hotel. Here’s a Google Earth street view image showing this side of the hotel:


Since the surface parking lot in the foreground could be developed (let’s hope!), this side of the Embassy Suites would be the adjoining wall with that new development. Here we can see the use of fake windows as a design feature to make the facade appear a bit more interesting until such time as it is covered up by an adjacent new development. In the center is a narrow vertical notch where the building has been stepped back enough to allow real operable windows to be used. Should the site in the foreground be developed, you wouldn’t have much of a view from those windows, but there would be sufficient space for natural light and air to enter the windows.

Option 3 is a full setback from the side property line on the upper floors of the building. This is the approach taken at Spire, as seen in this Google Earth street view image:


The two-story structure in the foreground and the small adjacent parking lot represent a prime redevelopment site. But rather than having a 42-story blank wall on this side of Spire, the developers chose to step the building back about 20 feet from the property line above the podium base, allowing all residential units on that side of the building to have windows. Should the site in the foreground be developed with a tower, even one without any setbacks of its own from the common property line, there would still be sufficient space to allow for natural light to enter the windows of those Spire units. Here’s a Google Maps bird’s eye view showing both the Embassy Suites and Spire and their sides facing future redevelopment sites.


By the way, also in the image above in between Spire and the Embassy Suites is the 6-story Aloft Hotel that recently opened. It too used the “blank wall” option for its side facing the small building next door, as seen in this Google Earth street view image:


So why isn’t Option 3 the one chosen in all situations like this? Answer: Loss of developable square footage. In the case of Spire, their 20-foot setback on the upper 34 floors cost them about 68,000 gross square feet of developable space, according to my rough calculations. But if you have a larger site like Spire’s and the goal of having an attractive building on all four sides, losing that square footage is a price you’re willing to pay. But if you’re a national hotel developer like White Lodging that’s interested in maximizing their development potential and not the architectural legacy of their projects or the aesthetics of the downtown skyline, then you put up a blank wall on the side property line and figure some day it may get covered up by a neighboring building. And if it’s a particularly small or narrow site, doing a setback on the upper floors to allow for windows facing the side property line could create a floor plate configuration that may become unworkable for the proposed building’s program.

A required setback from the property lines on the floors above the building podium is the basic model for the point tower, which Vancouver BC has implemented to an extreme degree.


What do you think? Should the “point tower” be the required model for all new buildings in Downtown Denver above a certain height?

Central Downtown: 1144 Fifteenth Update #7 (Inside the Infill Edition)

DenverInfill recently had a unique opportunity to check out 1144 Fifteenth Street from inside the fence, thanks to Dave Klebba of Hines!

It has been a while since we have seen a building over 600 feet under construction in Denver. That being said, the foundation and early construction processes are going to be a bit different. So what exactly is going on in the pictures below? Workers are drilling foundation piers that will go down over 100 feet. This will anchor the foundation which will get poured in the coming weeks. The large tubes of rebar, on the left, will get set in the hole which will be filled to the top with concrete.

Safety, with a hole that deep, is an obvious concern. Workers are harnessed to a slab of solid concrete to keep them from accidentally falling in a hole more than 10-stories deep. Also, check out the size of the drill bits being used!

2015-09-15_1144Fifteenth-03 2015-09-15_1144Fifteenth-02

1144 Fifteenth Street is making very quick progress and should be to the ground level by February. Then, it’s 12-floors of concrete and 28 floors of steel!

Central Downtown: 1144 Fifteenth Update #6 (Above the Infill Edition)

As I was ready to give you a great Capitol Hill infill tour, with around six new project updates, I misplaced my SD card right before I was able to download it therefore losing all the photos I was excited to share with you.

To make up for my week hiatus, I had the drone out and decided to take some shots of 1144 Fifteenth Street, which is now a giant hole in the ground! Flying just about as high as the tower crane, here are two sunset shots with 1401 Lawrence in the background.

Of course, no drone flight is complete until I turn it around to capture other views!


We will be utilizing aerials for 1144 Fifteenth Street as it climbs its way onto Denver’s skyline. I can’t wait!

Central Downtown: 1144 Fifteenth Update #5

I hope you aren’t getting sick of my tower crane posts yet because there is still a lot to cover as August is turning into the month of cranes. Over at 1144 Fifteenth, workers started erecting the new, red, top slewing tower crane.

But Ryan, you may ask, how do you know this is going to be a top slewing tower crane and not a luffing jib? Well, luffing jib cranes are used for tight urban spaces. They are usually near the center of the site, start out very short, and climb with the building. The tower mast for this particular crane is on the sidewalk, outside the project site away from the Four Seasons, and over 200 feet tall to clear its neighbor Park Central.

Because of the weather and wind, work on this crane will go into tomorrow. Here are some shots I took this evening of the work in progress.

How many tower cranes are around Downtown Denver and Cherry Creek? Luckily, I made a fun little graphic:


Now that’s a lot of cranes!

Central Downtown: 1401 Lawrence Update #8

Even though we recently did an update on 1401 Lawrence, a recent milestone has been reached: the parking structure has topped out with the first office floor underway.

Here are two shots of the project from this weekend. As you can see, the office structure has a significantly larger floor to ceiling height than the parking structure.

2015-07-27_1401Lawrence-02 2015-07-27_1401Lawrence-01

1401 Lawrence has 14 more floors to go which will make it roughly the same height as 1800 Larimer.

Central Downtown: 1144 Fifteenth Update #4

Downtown Denver’s skyscraper-to-be has a new piece of red, crane-base-like, equipment on site. That’s right, folks. A red tower crane will soon be flying above the 1144 Fifteenth site helping build a 603 foot, 42-story office tower!

2015-07-25_1144Fifteenth-01(I'm getting my picture taken!) 2015-07-25_1144Fifteenth-02

Can you guess what type of crane this is going to be?
