We are a 50-person architectural firm located in Denver, Colorado. For over 40 years we have provided a full range of services including the planning, programming, and design of buildings for colleges, universities, schools, libraries, justice facilities, office buildings, cultural venues, and housing. We have twice been awarded the American Institute of Architects' Firm Award for "a distinguished body of work" and numerous local, regional and national design awards.

We believe architecture has the power to heighten human well-being and illuminate our cultural values. We are driven by a standard of excellence which provides the highest level of ethics and professionalism to our clients. We embrace thoughtful and responsible design in all aspects of our lives and we constantly strive to create buildings of architectural significance and responsibility.

Our work is developed within a collaborative atmosphere which cultivates research, analysis, and deliberation into judicious decision-making at all levels. Vigorous exploration of client goals is coupled with a detailed examination of their functional needs. This understanding is artfully transformed into three-dimensional space which inspires the daily life within the building. Physical patterns and the cultural fabric of each place are carefully studied to appropriately respond to each site's unique physical and social context. Materials and systems are selected which respect and sustain our planet and the thoughtful expression of building craft and technology are economically integrated to bring the defining statement of character and identity for each of our clients.

3198 Speer Boulevard was originally constructed in two sections in 1925 and 1938, for an auto dealership. The building is a bowstring truss industrial structure that housed an open car showroom, offices along the front and a maintenance area that included service bays with hydraulic lifts in the back. In 2007, Anderson Mason Dale Architects purchased the building and realized a new home for our practice that is evolving with a new generation of partners and staff.

Following the patterns of the original layout, support spaces comprise the front of the building, including conference rooms, restrooms and staff kitchen, with our open studio occupying the back half of the building. The existing superstructure of the building was rehabilitated, preserving the antique character of the space, while contemporary finishes and highly-refined furnishing systems were introduced as counterpoint to the raw character of the volume.

The building's primary face, along Speer Boulevard and on axis with 32nd Avenue, was reconfigured to provide a more significant presence with large windows, perforated metal infill panels and a cornice structure. Large arbor screen walls may one day add another layer to this face, providing solar shading for its southwestern exposure. The site was redeveloped to re-introduce a right-of-way lawn to connect to the street fabric that occurs north and south of the building, while improving the pedestrian experience.
