Germany-based TMK Architekten Joins HDR Architecture

Words: Bronzella Cleveland

TMK Architekten • Ingenieure, one of Germany's leading healthcare architecture firms, is joining forces with HDR Architecture, the world's No. 1 healthcare and science + technology design firm. The merged company will conduct business as HDR TMK, and will be the hub for the firm's healthcare and science + technology design programs in Europe.

TMK has designed more than 1,500 healthcare projects throughout Europe, ranging from large-scale replacement hospitals to community clinics, surgical centers and outpatient facilities. The firm is well known as an innovator in designing contemporary buildings for health – buildings that are distinctively designed to focus on people and to aid in the healing process.

"This is an exciting announcement for both HDR and TMK and a key part of our global strategy," says Doug Wignall, president of HDR Architecture. "As a firm, HDR has made a commitment not only to designing projects all over the world and bringing the best ideas from around the globe to our clients, but to establishing a permanent presence in strategic locations around the globe. We are excited about the opportunity to blend the unique perspective that TMK offers as a German healthcare practice into HDR's global team of thought leaders from North America, the Middle East and the Pacific Rim."

Reflecting on the merger of the practices, Guido Messthaler, a senior partner with TMK Architekten, notes that, "Both firms are compatible on many levels, specifically in our commitment to our clients and to design excellence." He continues, "The merger will deepen our healthcare expertise and enable us to reach deeper in the European marketplace. And with access to HDR's expertise and portfolio, we will also be able to further develop work in the science and technology and higher education markets."

HDR Architecture employs more than 1,300 professionals in 44 offices worldwide, including offices in the United States, Canada, China, Europe, the Middle East and Australia. With the addition of TMK, more than 20 percent of HDR Architecture's employees are located outside of the United States.
