It’s not an infill project, but it is an important renovation of an existing building in the core of Denver’s Central Business District. I’m talking about 1800 Glenarm, the unique three-sided 14-story office building on Block 193.

St. Charles Town Company recently purchased 1800 Glenarm and is in the process of a “green” renovation of the entire building into office condominiums. Here are a few images of the building after the conversion:

From the company’s 1800 Glenarm press release, here are additional details about the project:

“This building’s unique small floor plates (4,452 SF) allow business owners the opportunity to purchase most or all of an entire level, with direct elevator access. Expansive new windows at each corner allow views and natural light to flow from all directions. Space plans and finishes can be designed to meet each owner’s specific needs.

The building’s new elegant, contemporary lobby will make a statement with terrazzo flooring, Eucalyptus wall paneling and modern lighting. The lower level of the building has a number of common amenities including two handsome conference rooms with adjoining kitchen, a fitness area, showers, and a bicycle room.

1800 Glenarm is being redeveloped using green building practices. St. Charles Town Company will reuse the majority of the existing building structure. ‘Recycling’ this 60,000 square foot building structure will save the equivalent energy of 760,000 gallons of gasoline and 4,800 tons of construction waste. In order to vastly improve 1800 Glenarm’s energy efficiency, St. Charles Town Company will be performing an extensive overhaul on the building’s systems including new high-efficiency heating and cooling systems, Low-E windows, a new high-albedo (reflective) TPO roof membrane, and a wind turbine. Common areas will receive low-VOC paints to improve indoor air quality. Conference rooms will have Energy Star-rated appliances. Restrooms will have occupancy sensors to save energy, as well as highly-efficient water closets and fixtures to lower water use. Overall, the core & shell building is being engineered to exceed the IBC-2003 Energy Code requirements. St. Charles Town Company will also be providing buyers with the option of a sustainable tenant finish package that features materials such as concrete kitchen countertops, bamboo woodwork, and natural fiber flooring.

1800 Glenarm is conveniently located on Broadway, one block north of 17th Street – Denver’s Wall Street of the West. The iconic Brown Palace Hotel is just around the corner. Within a short walk are the 16th Street Mall, Colorado Convention Center and some of Downtown Denver’s best restaurants. The building has direct walking access to multiple modes of alternative transportation being within two blocks of the 20th & Welton light rail station, Civic Center Station, and the 16th Street Mall Shuttle. 1800 Glenarm will also have bicycle storage, showers, and changing facilities in the lower level of the building, making it convenient for owners and their employees to take advantage of this free transportation option.

St. Charles Town Company ( is an established Denver-based development firm led by its President, Charlie Woolley. The company is best known its work redeveloping the historic Equitable Building into a very successful office condominium project, as well as the Lowenstein Theater redevelopment – home of the Tattered Cover Book Store on East Colfax.”

In addition to Downtown Denver’s many new construction projects, it’s great to see all the renovation/conversion projects that are taking place in Downtown too, like 1800 Glenarm. They can be just as important as new construction, as a tired, underutilized building can often have the same detrimental effect on the vitality of its surrounding area as a surface parking lot. Whether renovation or new infill, the massive investments in Downtown Denver continues.
