CDA – Charles Diehl Architect was founded in 2009. We are a full-service architecture firm with experience in the residential, commercial, and institutional sectors. Our work includes new buildings and renovations, ranging in scale from single-family dwellings to multi-story mixed-use towers. We have developed designs for restaurant interiors, custom homes, commercial spaces, apartment buildings, and religious institutions. We are proud to have worked on many unique projects such as Landmarked properties and sustainable designs.



We make it our aim to provide a high level of professional service tailored to the unique needs and requirements of each client and project. When clients come to us with a proposal, we first take the time to research the site and analyze its development potential. In partnership with the client, we develop a design based on technical, environmental, and aesthetic considerations. Seeking out the best solutions possible, we collaborate with engineers, designers, and consultants who provide necessary services and valuable input at various stages of the project. We navigate each project through the approval process with the Departments of Buildings and other city agencies. We continue to be involved with each project as it moves into the construction phase, mindful of adjusting for the unexpected. Our aim is to ensure that our clients invest in projects that have lasting value and make a positive contribution to the neighborhood and community.
