The Firm


The firm seeks to practice in classically inspired architecture blending classicism, timeless design and functionality. Based in Oklahoma City, OK the firm strives to build a substantial and varied body of work across the region for Institutional, commercial, and residential commissions. For the past thirty years, Darrell McAllister and his colleagues have grounded projects in a forward-looking interpretation of history; they believe that architectural practices in the past leave us potent lessons that are relevant to contemporary architectural challenges.

The staff is dedicated to our clients’ success. We believe the most successful projects are the result of building trusting relationships through teamwork, stewardship and open, honest communication. Each project becomes a collaborative effort that synthesizes the premises of the program, the voices of the client, and the creative talents of the architects, designers and engineers. 

Our Story

Design trends come and go. Proven design principles that brought classic communities are often lost to faceless modern design without true character, meaning and connection to people and their communities.  

Having grown up in a traditional family, worked in and led another firm for 20 years and recognizing the value of organizational and spiritual principals, Darrell decided to pivot the new firm to a more structured design narrative that includes the study, research and application of proven, relatable and timeless design principles used by the most respected and well-known architects for 100’s of years. This principle approach will yield buildings and spaces that give people a stronger sense of identity, more balanced and harmonious environments and develop more cohesive communities. 

By focusing on the practical application of the classic design principles of human scale, balance, harmony, rhythm, proportion, contrast, context and pattern and their application in a complex and technology rich society, the firm seeks to educate, inform and lead people to realize the value and return-on-investment of timeless beauty, pragmatic function, efficiency and context.

McAA knows that when clients build, they are making an enormous commitment of time and money to what is expected to be a valuable and productive investment. We believe our prime responsibility is to be good stewards of the resources entrusted to us. This task includes adherence to budget, respect for time and schedule, and the prudent use of land, labor, natural resources and materials. Our design should enhance its environment and grow in value over time.
