Denver International Airport South Terminal Expansion Final Update

As we all know, the A-Line from Denver Union Station to Denver International Airport opened over the weekend. We, here at DenverInfill / DenverUrbanism, took the opportunity to photograph the great new transit line along with the south terminal expansion over at DIA.

Back in February 2012, we provided the renderings for the project but never did any construction updates. Now that this project is complete, it is definitely worth covering.

The signature structure in the expansion is the 500-room Westin Hotel. Resembling wings, or how ever else you would like to interpret it, the 15-story building creates a whole new look for the airport. Here are a few photos looking at it from the new Denver Airport commuter rail station.

Also included in the expansion is a 60,000 square foot plaza that connects the Jeppesen Terminal with the new hotel and rail station. Once you leave the Jeppesen Terminal, also known as the great hall, you are greeted by a glass canopy that protects you from the elements. It also covers the escalator that goes down to the rail station.

The plaza is a great public space where the airport can hold events, live music, and festivals. In these photos, everyone was gathered for the A-Line grand opening ceremonies.

Back under the glass canopy, there is enough room for a stage and ample seating.


The south end of the plaza looks over the rail station canopy and offers views of the mountains on a clear day.

A balcony runs along the entire hotel and features patio space for the retail that lines the plaza. This space will be open 24 hours which will be great for passengers and visitors!


The hotel lobby is a spectacular sight with an arched ceiling and glass curtain walls on both ends.

What a great view of the commuter rail station!


That wraps up the South Terminal Expansion. Keep your eye on DenverUrbanism this week for all of the great A-Line festivities that went on over the weekend.

Six Years of Downtown Denver Infill… In One Chart!

Happy 2016, Denver!

We recently recapped the extent of multifamily residential and non-residential development in Downtown Denver since 2010 using maps and tables to show some of the basic attributes of the 142 different projects—completed, under construction, and proposed—that are reshaping Denver’s urban core. Remember the general premise behind DenverInfill: surface parking lots are soul-sucking black holes in the urban fabric of the city, and with each new infill development, we repair the urban fabric, add vitality through economic and social activity, and improve the walkability of the area. A few millennia of city-building have taught us that successful communities are those with an intact and coherent urban form, a mix of uses in a compact built environment, and an exceptional public realm oriented around the pedestrian. This is our goal for Downtown Denver.

To complete DenverInfill’s look back at the first six years of the decade and the remarkable transformation taking place in Downtown through infill development, I offer the following exhibit. It started out as a straight-forward infographic, and then as I kept fussing with it, it evolved into something a bit more artsy and elaborate. But either way, I had fun making it (gotta keep those Adobe Creative Cloud skills sharp!) and I hope you enjoy looking at it. Click to embiggen, of course, and yeah, it’s kinda big.

Here’s to a successful and prosperous new year for Denver and for you!

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?

Aria Denver Update

A little over a year out from our initial post, I’d like to turn our heads to the progress of Aria Denver. Since its groundbreaking in August of 2012, we have got buildings constructed and new residents entering the neighborhood. In this update, we will look at what’s on the ground, but also take a look at some of the changes that inevitably occur over the course of a multi-phase project such as Aria. [note site changes since August 2012]

Previous Plan

Current Plan

At current, Aria is only about 19% built out. About 76 out of some eventual 400 units are currently constructed, but the project scope is quite complex. With a diversity of living arrangements, some units will be constructed around a pocket neighborhood design that will put residents in an intimate physical environment that promotes social interaction. Townhomes will also play a role, as will large footprint apartments buildings. Also, as mentioned in our original post of Aria, plans for a cohousing component are still moving forward. The newly completed construction of town homes and multi-family units give us an idea of how their design will transform the site, and neighborhood.



In a residential market that is used to building boxes (maybe with a community room or a pool), Aria is going beyond the standard to bring about a holistic approach to living. If you were to visit Aria today, you would see the attention to detail that makes this project so special. Community spaces are abundant, stormwater systems have been crafted into one-of-a-kind landscaping features, the properties are surrounded by a jungle of native plantings and programming the new construction with the surrounding neighborhood is a cornerstone of this development.

With Regis University neighboring this project, there has been discussion of making room in Aria’s plans to include student housing opportunities for their growing student population. For those already established residents living within a stone’s throw of Aria, an investment has been placed in community-building programs surrounding food, transportation and overall neighborhood health. Working with UrbiCulture, a portion of the site will be transformed into 18 raised beds to generate food for what will eventually become a “pay what you can” marketplace at Elm & 52nd Avenue.  This garden will begin at 10,000 SF and eventually grow to 1 acre. At that point, the garden will be large enough to produce food for purchase by local restaurants. That money will then be reinvested to community education programs on urban agriculture.



Beyond agriculture, the project team (Urban Ventures LLC and Perry Rose LLC) is also considering plans for a bike program to put the local community in touch with accessible alternative transportation. Quality of life, and balance, are a continued focus in the on-site retail options. Where Aria originally had plans for retail on site, they are now making a concerted effort to bring in businesses centered on fitness, natural foods and overall wellness.

So what’s next for the project? By spring or summer of 2014, 9 additional townhomes will fill out the project site. Most of 2014 will see continued townhome development. Commercial space will likely be open and available by 2015 and final build-out of the site should commence by 2017.  To get a more comprehensive view of Aria Denver, take a virtual tour of the project here!

Aria Denver Breaks Ground and Breaks the Mold

When infill is discussed here on the blog, we are most often referring to an instance of revitalizing the entirety, or part of, an urban city block. Well, a little over a week ago, Denver saw the groundbreaking of one of its largest infill redevelopment projects in years. Immediately east of Regis University at W. 52nd and Federal Blvd. (eight blocks from the Gold Line light rail), Aria Denver has positioned itself to be not only pronounced in size, but also in its distinct flavor of design.

The unique aspects of this development are the product of its wholesome past. Once a fruit orchard, turned convent, the 17.5 acre site has been occupied since the late 1930s by the The Sisters of St. Francis. After the Marycrest Convent saw their resident population fade from several dozen nuns to just seven, they began exploring options for redeveloping the site into something that met their needs, and also the community’s. After searching for a developer that could understand and respect their vision, the sisters teamed up with development partners Urban Ventures and Perry-Rose.

As Susan Powers explained, “The sisters placed a great deal of trust in us to develop the land in a way that would align with their mission and their values.” At the heart of this development, community has really become the focus. Though many residential developments may jump to make that claim, it is completely evident in this case. It is shown through the amount of intelligent planning, programming and quality of design represented throughout each component of Aria.

In 4 phases, 380 new homes will be built in the form of townhomes, apartments, condominiums and senior housing. What takes the community aspect beyond the typical neighborhood is its co-housing component. A portion of the housing will be designed and programmed in a way that connects people and encourages interaction. In co-housing, residents play a large part in developing their community by helping to design, and eventually share, certain amenities like a community kitchen, gardens, green spaces, and other common facilities. In Colorado, several examples of co-housing can be found in Boulder, but the concept is still quite innovative for Denver.

In addition to internal community functions, developers also provided opportunities for the greater neighborhood outside of the development. Approximately 20,000 sq. ft. of retail space will sit as the hood ornament of this development to provide new commercial assets to residents of Aria, but also to enhance Federal Blvd. One other community-building element is that both affordable and market rate housing will be available to make the lifestyle accessible to more people.

Taking a step away from programming, aesthetic design is one of the other outstanding attributes of this redevelopment. In addition to Urban Ventures and Perry-Rose, other collaborators include Oz Architects, Humphries Poli Architects, Wenk AssociatesCalthorpe Associates and award winning architect, Michelle Kauffman. Kauffman is known for her modular sustainable designs that have a distinct contemporary flair. As a result of being modular structures, they will be prefabricated and, therefore, will reduce waste, eliminate weather damage to materials, expedite construction, cut back on construction site pollution and prevent cost overruns.


Other sustainability wins in the project are evident through the conformity of all residential uses to follow the Enterprise Green Communities Criteria. As part of that standard, recycled materials will be used throughout, units will be equipped with low VOC products (exterior materials, windows, etc.), alternative energy will be sourced, and energy/water conserving appliances will be installed into each home. The entire site will also utilize innovative storm water designs to boost sustainability and water-conserving native plants will dress the landscapes.

Aria brings sustainability, co-housing/community building, and high design to the same table and delivers the final product in a way that pays tribute to the good intentions of The Sisters of Saint Francis. At the same time, it will also bringing Denver a totally new alternative lifestyle. Ground was broken on August 8, 2012 and the first batch of units should be available for move in by Spring 2013.

Denver International Airport Terminal Expansion Update

Let’s take a look at the latest designs of the exciting expansion that’s getting underway at the terminal at Denver International Airport. The $500 million expansion incorporates three major elements:

A new Public Transit Center that will accommodate the end-of-line station for RTD’s East Line—a 23-mile rail transit connection between DIA and Union Station in Downtown Denver—currently under construction and scheduled to open for service in January 2016.

A new 500-room Westin Hotel & Conference Center that will be located immediately south of the existing Jeppeson Terminal and above the Public Transit Center.

A new 60,000 square foot Public Plaza that will connect the Jeppesen terminal with the new hotel.

Gensler is the principal architect of the entire South Terminal Redevelopment program at DIA, with Anderson Mason Dale working on the Public Transit Center. Here are some new renderings of the project, courtesy of my friends at Gensler’s Denver office. You have two options to view the renderings: click on an image to view a larger version of it, or use the link below an image to open a giant-sized version in a new window. Here we go:

Denver Parking Lots Continue to Vanish

As 2012 opens with a number of slated large-scale residential projects, we will say goodbye to numerous swaths of desolate concrete.  Where a few dozen cars once spent their day sunbathing, we will soon see several hundred people injecting life into 2785 Speer Boulevard.  Thanks to the vision of developers Allied Reality Group and architects Meeks + Partners, this new project will provide even more housing opportunities within walking distance of Denver’s urban core.

Keith Malone, Associate Partner at Meeks + Partners, informed that a real focus of the 325-unit project would be integrating the neighborhood and surrounding spaces with the 4.5-acre site. Design elements will borrow similar materials and textures of the surrounding structures to compliment the character of the neighborhood. However, sleeker features will also be incorporated to continue the trend of painting Denver’s urban landscape with modern design.  In addition, a “pedestrian spine” will split the project into two mini-blocks which should enhance connectivity and promote appropriate scaling.  As a mixed-use development, 2785 Speer will also provide residents, and the neighborhood, with 10,000+ sq. ft. of retail space.

Other design features which will help to set this development apart from others around the city were also noted.  Keith Malone mentioned that one of the most defining features, and also greatest challenges for 2785 Speer, is the topography.  The unique panoramic views of the city that are so characteristic of the Lower Highlands and Jefferson Park, will showcase the Denver skyline.  While the views will draw attention to urban life outside, courtyards will absorb residents into more intimate spaces at the nucleus of the buildings.

It is likely that the project will break ground by spring of this year.  It will aim for completion by the end of 2013.  For more information concerning 2785 Speer Blvd., click on the following link:

Inside the Infill: Ralph Carr Judicial Center Part 2

Just a block away from History Colorado Center is the State of Colorado’s new judicial complex, officially known as the Ralph L. Carr Colorado Judicial Center. Ryan just posted Part 1 of this “Inside the Infill” feature, so here’s a second dose of infill goodness for you to enjoy. Rumor has it there may be a Part 3!

The Ralph Carr Judicial Center is already making an impact on the Civic Center skyline, and I like it. The architecture is classic Neoclassical, with marble columns and all. The state courts wanted a building that communicated a stately, civic presence on par with (and visually oriented towards) the State Capitol, and they are getting it. But despite the Ralph Carr’s architectural gravitas, I find its contemporary touches and generous fenestration (for this style) welcome features that give the building an inspiring, approachable quality. And it’s not even finished yet. Kudos to Denver’s Fentress Architects for designing a building that is clearly worthy to take its place at Denver’s hallowed ground, Civic Center. Our thanks to Trammell Crow and Mortenson Construction for the tour.

I like the exterior materials too. A light gray granite wraps the 4-story courthouse wing as well as the lower levels of the 12-story office tower, and pre-cast panels complete the upper floors of the tower. They work well together to give the complex a unified visual appearance, while exposing pedestrians to the high-quality material like granite we expect in important government buildings. Here’s a view (an inner courtyard along Broadway) of the vertical transition from granite to pre-cast panels. The darker-gray window glazing complements both materials. This wasn’t intentional, but I now notice the nice reflection in the window of perhaps Denver’s best light gray granite-clad modern building, Republic Plaza:

The office tower incorporates into both its north and south facades the columnar form, with vertical glass “columns” in between adding a modern gesture.

Before we we went up to the project’s upper floors, we saw a quick preview of Mortenson’s digital planroom technology. More on that in a future post. Then we took a ride in the construction elevator “cage” that climbs up the outside of the building:


From the 12th floor, here’s a nice view of the two courthouse domes: the smaller one in the foreground will be centered above the Colorado Supreme Court courtroom, and the larger one will cover the grand atrium. On the right, a stack of windows are being lifted up by a crane while traffic below on Broadway goes about its business:


From the Supreme Court’s fourth-floor atrium entrance, here’s the symbolic view looking back at the statehouse. Once all the scaffolding and temporary window supports are removed, this will appear as one big window offering one fantastic view of our state’s beautiful gold-domed Capitol.

Finally, while we now have real-life views of this project to observe, I recently ran across some additional renderings of the project I hadn’t seen before. They can be viewed here.

PS. If you don’t know who Ralph Carr is and why he is worthy of having a justice center named after him, please go here.
