ENR Mountain States, working in concert with other regional ENR publications and editors across the U.S., has selected its Design Firms of the Year for 2016.

This year, they are OZ Architecture, Denver, for the Colorado/Wyoming area; and CTA Architects Engineers, Billings, Mont.,  for the Intermountain area. Both firms were chosen by a vote of the regional ENR editors from a solid group of finalists.

OZ Architecture

OZ is a multi-faced design and master-planning firm with deep roots in Colorado and the Mountain West. The firm’s design services encompass a broad spectrum of markets, from higher education and K-12 projects, health care facilities, retail and hospitality, government buildings, energy and technology centers and global work to interior design projects.

Here is a small sample of the firm's notable regional projects:

  • The Confluence Building for Community College of Denver
  • The LEED-Gold Visual Arts Complex at the University of Colorado
  • Many well-known Colorado restaurants and hotels, including Elway’s at The Lodge in Vail, multiple locations for Punch Bowl Social, The Nickel at the Hotel Teatro, the Westin Snowmass and Westin Riverfront.
  • Institutional work includes Fire Station No. 18 in Lowry, the Glenwood Springs City Hall, the Pearl Street Mall and Boulder Community Foothills Hospital.

OZ also has designed dozens of global projects, from Africa to the Middle East. The firm celebrated its 50-year anniversary in 2014.

CTA Architects Engineers

CTA is headquartered in Billings, Mont. The multidisciplinary design firm has 17 offices throughout the West, with 400-plus employees working in six vertical markets: commercial, education, government, health care, living and retail.

Some of the firm’s recent projects in the region:
