New Adaptive Reuse Project: Steam on the Platte

Tucked away in the industrial stretch along the South Platte River below Mile High Stadium is a new adaptive reuse project, Steam on the Platte, which will bring urban energy to a part of Denver near downtown that hasn’t seen a lot of private-sector investment in the past century. Steam on the Platte is being developed by Urban Ventures and White Construction Group.

Located at West 14th Avenue and Zuni Street, Steam on the Platte is technically in the La Alma/Lincoln Park neighborhood. However, because it lies in a narrow zone of land east of the river but west of Interstate 25, the location feels less La Alma/Lincoln Park and more Sun Valley, the neighborhood located on the west side of the river. The 3.2-acre site lies approximately half way between RTD’s Decatur-Federal and Auraria West Campus light rail stations and, just to the south, is Xcel Energy’s Zuni plant, which is planned for decommissioning in the near future.


In Phase 1, Steam on the Platte includes the restoration and reuse of four buildings, the largest of which is a 65,000 square foot brick-and-timber warehouse at 1401 Zuni constructed in 1928. Here’s a site plan, courtesy of Urban Ventures:


The new uses will include work space for tech and creative companies and a café. Here’s a before-and-after shot (courtesy of Urban Ventures) of the historic warehouse:


Below are a few renderings of what the inside of the historic warehouse will look like after the project is finished. These images are courtesy of tres birds workshop, the architect for the 1401 Zuni building renovation:



One of the other existing buildings that’s located right next to the river will be converted into a signature restaurant space. Several landscaped plazas and gardens will tie the entire complex together and link the development to the river. This rendering, courtesy of Wenk Associates, the project’s landscape architect, shows the proposed plaza space adjacent to the historic warehouse:


Phase 2 of the project envisions adding several new buildings for more office space and to bring multi-family residential uses to the development. This final rendering shows the vision for Steam on the Platte after Phase 2, as viewed from across the river. Click to embiggen!


Phase 1 should be complete by Fall 2016.

14th Street Ambassador Corridor Improved by Renovation at 414 14th

Recently I was able to get a peek inside the former Denver Public Schools Administrative Building at the corner of 14th Street and Tremont in the Central Business District.


This gorgeous building, now known as 414 14th Street on the Ambassador, was originally erected in 1923 for the Denver Public School system and housed their offices until the 1970’s. It was added to the City and County of Denver’s list of historic landmark buildings in 1994. Most recently, it served as offices for the Denver Art Museum.

The Downtown Denver Partnership has designated the 14th Street corridor the “Ambassador Street” because of its proximity to sites popular for out-of-towners, such as the Colorado Convention Center and the Performing Arts Complex. The building’s prime central location on the Ambassador Street, along with its historic importance, caught the eye of owners Dunkeld-14-LLC (a partnership that includes principals from Hyder Construction). They closed on 414 14th in 2013 and with the help of DURA financing, they are in the midst of performing an impressive renovation.

Redeveloped on spec, Dunkeld-14 is now seeking tenants through Pinnacle Real Estate Advisors to fill this 43,000 square foot office space. Tenants could potentially lease the entire building, or subdivide the three floors into multiple offices. Though many of the original building’s details are being restored (like the stairwell and hallway pictured below) each lessee will have the rare opportunity to select their own finishes.



Though the owners are not currently seeking LEED certification, the building is being adapted to meet LEED-Silver standards. Negotiations with Xcel Energy have resulted in a brand new electrical system, with a state-of-the-art transformer vault installed at the rear of the building. High speed fiber-optic cable was added, and the interior features a brand new variable refrigerant flow (VRF) HVAC system that offers up to 35% in energy savings because of its ability to allow for zoned thermal control in large spaces.


All of the 150-some original windows were sent out of state to be professionally insulated and glazed, preserving the original character of the building while bringing it up to today’s energy-efficient standards. Lower level bike storage and shower rooms will cater to the cyclists in the city, while 42 dedicated parking spaces at the rear of the building are an undeniable bonus for potential tenants.

The 3-story building was originally shaped like a U, with the open space facing the rear. Dunkeld-14 has added an impressive secondary entry alcove to this space that adds over 6,000 square feet to the original building footprint.


With its unique blend of modern technological improvements and historic 1920’s charm, 414 14th is sure to be snapped up soon. We’ll check back in for an update when the renovation is complete.

Thanks to Jeff Caldwell at Pinnacle Real Estate Advisors for the tour!

Montessori Academy of Colorado Renovates Ideal Laundry Building

The Montessori Academy of Colorado (MAC) elementary school recently completed phase one of its multi-million dollar restoration of the Ideal Laundry building in historic Curtis Park.


With the help of New Markets Tax Credit Loans (a federal program designed to stimulate economic growth in low income urban neighborhoods by providing private investors in Community Development Entities with tax incentives), and the Denver Office of Economic Development, MAC was able to finance a renovation that nearly doubles the usable square footage within the building.

Occupying nearly half of the 2500 block of Curtis Street, the Ideal Laundry building has been a prominent fixture in the Curtis Park neighborhood for over one hundred years. According to a 2010 Application for Landmark Designation to the Denver Landmark Preservation Commission, the building was initially erected in 1910 as a laundry facility where artesian well water was pumped on site. The building changed ownership several times over the years; additions were made, interior walls were erected and dismantled, and exterior doors and windows were boarded up and then uncovered again.  The photo below is from the Denver Public Library’s digital collection, taken in 1988 when the building was home to a watering hole called Eric’s Pub.


Adapting an historic industrial facility for use as an elementary school is a complicated venture.  Since they purchased the building in 2007, MAC has replaced the outdated HVAC system, the roof, and the smoke detection and alarm systems. This most recent renovation converted spaces like the one pictured below into several new classrooms, a library, art and music rooms, a small kitchen, staff lounge and conference room.


Though the interior of the building is being completely upgraded, MAC has managed to preserve some of the original character of the building, as you can see in the photo of the windows of the infant care room below.


Phase two of MAC’s renovation (“Future Phase” on the Slaterpaull Architects rendering below) is scheduled to begin later this year and will include a media center, gym, and rooftop garden. Many thanks to Abby Hagstrom, Jaclyn Greenbaum, and Nancy James for the tour!


Industry Denver Accelerates River North Revitalization

By Liz Munn

If you’ve been to the River North (RiNo) neighborhood lately, you may have noticed that INDUSTRY at 29th and Brighton Boulevard is buzzing with activity. Located in the former Denargo Market area that once housed over 60 food vendors and wholesalers circa WWII, 3001 Brighton Boulevard is now the anchor for an ambitious redevelopment project that brings office spaces, restaurants, and residential living to the nine-acre site.

Here is a photo of the revitalized warehouse building taken from the other side of Brighton Boulevard:


The interior features 120,000 square feet of shared office spaces that range in size from a single desk to 5,000 square feet. The development took place in two phases, with every space leased before construction was even completed. The lessees are predominantly creative-tech companies, such as Uber, who is the anchor tenant for Phase 1 of the development. Companies share a café, dining area, a few kitchens (one of which always has a keg on tap), common areas and conference rooms.

Here are a few photos of the building’s shared spaces:





The building’s original skylights were restored, allowing abundant natural light to brighten what could have been a shadowy and cavernous warehouse space.


Industry’s north-east side currently houses Tengu, a noodle shop. Two more restaurants, The Griffin and Will Call are currently under construction and slated to open for business within the next couple of months.

Though the redevelopment of the former market is almost complete, construction is far from over at the Industry site. Phase III is currently under way, a building that combines three floors of parking with two floors of office space, expected to be complete by early 2015. Eventually, the parking lot that currently sits to the north of the building will be razed and replaced with townhomes.

Here is a rendering of the completed development, courtesy of Industry:

Colorado National Bank Hotel Conversion Final Update: Part 2

In Part 1 of our coverage, Ryan gave us a comprehensive overview of the grand opening of the new Marriott Renaissance Denver Downtown City Center Hotel that has been carefully crafted out of the historic Colorado National Bank building at 17th and Champa in Downtown Denver. In this post, we’ll add a few more photos of the project and some additional observations.

This project is a HUGE win for Downtown Denver. Take a classically historic building and transform it into a new hotel, with the modifications approved by the Denver Landmark Commission:



This building was vacant for about a decade. Thanks to Stonebridge Companies and the Denver Urban Renewal Authority, this historic building was transformed into the beautiful building it is today. Here’s a photo of Councilman Brooks and others from the development team cutting the ceremonial ribbon on June 5, 2014:


A few more images of the building at grand opening:



If you haven’t yet checked out the inside of this awesome historic structure, featuring a stunning three-story atrium of white marble colonnades and a series of historic murals by Colorado artist Allen Tupper True, I highly recommend you do. The lobby bar and the hotel’s restaurant, Range, are fantastic.

While infill development is a big part of Denver’s growth as a city, adaptive reuse projects like the Marriott Renaissance Denver Downtown City Center hotel are equally important to Denver’s urban evolution and preserving its heritage as a major city.
