Robert R. Roth R.A.

Principal Architect & Project Manager


Bob has over thirty-five years of experience in the Architectural and Interior Design profession having worked on projects ranging from tenant improvement to corporate design. These projects have ranged from as little as a 1,000 sf. retail space to a 200,000 sf. corporate office. Bob believes that every project must be true to its use. In order for a design to be a success it must be appropriate for the client and their needs. The functionality of a design is of tantamount importance to its success. At the same time, he believes that thoughtful and creative design is required to develop a pleasant space within which the client will feel invigorated as well as comfortable. The blending of creativity with efficiency is what makes a truly successful project.
