RTKL is a global architecture, planning and design firm. The firm was founded in 1946 by Archibald Rogers and Francis Taliaferro in Rogers’ grandmother’s basement in Annapolis and is now one of the largest architectural firms in the world. Its award-winning portfolio spans six continents and includes projects in the retail, entertainment, residential, healthcare, civic and public, workplace, mixed use, hospitality, urban planning and technology sectors.

The firm has consistently been ranked among the world’s top design firms. In 2011, Building Design ranked RTKL’s retail sector first in the world, its planning services third and its urban design services fifth.

In 2007, RTKL became a wholly owned subsidiary of Arcadis NV, an international company that delivers consulting, design, engineering, urban planning, architectural and project management services for infrastructure, environment and buildings.


The firm was founded by Archibald Rogers in his grandmother’s basement in Annapolis. Francis Taliaferro joined shortly afterwards.[1] In 1949, the pair added Charles Lamb, whose design for the Anne Arundel County Girl Scouts Teepee Lodge gained the firm national attention by winning an award from the American Institute of Architects. The firm’s reputation grew when, in 1954, internationally renowned architect Pietro Belluschi selected Rogers, Taliaferro and Lamb as his associate architect for the design of the Church of the Redeemer in Baltimore. The project received an AIA Award of Merit and, in 1986, a special 25-Year Award from the AIA's Baltimore Chapter. The addition of urban design specialist George Kostritsky in 1961 completed the foursome, and the “Rogers, Taliaferro, Kostritsky and Lamb” name was condensed to “RTKL.” In that same year RTKL was commissioned to design the public spaces for the Charles Center, which contributed to Baltimore’s urban renewal movement. Largely because of the success of this involvement, the firm was commissioned to develop downtown plans for Cincinnati, Hartford, and Charlotte, North Carolina, among other US cities.

The firm continued to expand in the next decades, opening offices across the company and overseas. In 2000, RTKL acquired Dallas-based FDS International, a health practice ranked among the top ten in the country. Ten years later the firm added Beijing-based AHS International, a practice that specialized in healthcare and medical-facility architecture.
