Design is a process of exploring possibilities.  Architecture is a fusion of aesthetics, function, and construction practices. In the urban locations where most of our work is found, the needs and desires of many voices, from the client, to the community and government agencies are incorporated.  Our approach embraces these complexities as the inspiration and opportunity for unique and thoughtful architectural design, and as the basis of architectural authenticity.  From the first feasibility studies through to the completion of construction, we strive to create works of architecture with integrity, aesthetic beauty, and clarity.


ECA is known for transformational residential and mixed-use projects.  When Eric Colbert founded the firm in 1982, the work was primarily rehabilitations of deteriorated apartment buildings for low and moderate income residents.  Beginning in the 1990’s, ECA’S work consisted of renovations and new construction of apartment houses for market-rate rental and condominium residences.  Retail street levels and other mixed-use functions appeared in the firm’s work in the 2000’s, new construction started to predominate, and average project sizes increased.  In these post-Great Recession years, ECA has added Executive Architect to our range of offerings, working with some of the biggest names in American architecture, while continuing to expand our own design portfolio. ECA has received numerous design awards over the years, and has emerged as one of the leading architects of Washington DC’s urban renaissance.


ECA’s primary goal is to design buildings that enhance urban communities. Our work ranges from sensitive restorations, to thoughtful insertions within historic districts, to boldly modern new structures.  We strive to create buildings that both fit in and bring new life to their neighborhoods. ECA has nurtured a culture of excellence through intra-office educational programs, tours of projects under construction, and a collaborative work atmosphere. One hallmark of ECA is a high degree of employee retention, ensuring continuity that is critically important for multi-year projects.
