TSW (formerly Tunnell-Spangler-Walsh & Associates) is an award-winning, full-service planning, architecture, and landscape architecture firm with approximately 40 full-time employees based in Atlanta, GA with additional offices in Tulsa, OK, Chattanooga, TN, and Lexington, KY. Maintaining a smaller office size allows our principals to be hands-on in every aspect of a project and allows for more multidisciplinary collaboration. TSW works throughout the Southeast on projects ranging from downtown planning studies to mixed-use developments to streetscape projects. 

We are committed to developing sustainable places for future generations through a community planning and design process that links tradition and context with today's cultural and environmental demands. Central to this process is an approach thoroughly grounded in the principles of New Urbanism.

As a full service firm, TSW is able to take a project from the conceptual phase to master planning to permitting to construction documents and through all of the critical steps in between. We are not only committed to creative and innovative designs, but also think in terms of implementation and the actual built product, which ensures an efficient overall process.
