Antero Resources — currently the most active operator in Marcellus Shale — is an independent exploration and production company engaged in the exploitation, development and acquisition of natural gas and oil properties located in the Appalachian Basin. Although the company has a presence in a handful of states in North America, it planted its roots in Denver, CO, more than a decade ago in the LoDo [lower downtown area of Denver] district. To accommodate its fast-growing business, about two years ago, Antero made the decision to relocate a couple of blocks away to One Union Station, a five-story, 110,000-square-foot office building, adjacent to Denver’s historic Union Station — a project that was finally completed a couple of months ago.

“Antero is a relatively new, but fast growing energy company,” said architect Mark McPherson, AIA of McPherson Architecture in Denver, CO. “Their existing offices were located in a series of small, turn-of-the-century buildings in LoDo and they occupied spaces from past tenants. As the company grew and went public, they needed a real headquarters and chose One Union Station, a new building adjacent to the historic Union Station and its new multi-modal transportation center. The Union Station re-development project is fast becoming the new center for downtown Denver, and Antero Resources is in one of two centerpiece buildings that front the Union Station plaza.”
