Design Philosophy

Pierce/ Cooley Architects, Inc. approaches every project as a unique opportunity to create buildings and environments that meet the needs of its Clients, improve the quality of the communities in which they are located, function for the Occupants and User’s and that create places that people enjoy. P/CA limits itself to no set design style and believes that its projects should enhance or set the standard for the fabric of the communities they are within.

P/CA believes that quality design, response to the environmental elements that affect a structure’s design and efficient programming contribute to the longevity of any built project.  An entire design team that is focused on the overall environmental performance of our projects will provide its Clients with the most responsible application of their construction budget dollars. P/CA’s design approach accounts for:

  • Analysis of location and environment
  • Analysis of the buildings desired functional performance
  • Analysis of the project budget
  • The building’s mass, form and orientation
  • An evaluation of applicable structural, mechanical and electrical systems, and the selection building materials that contribute to time-tested performance


Pierce/ Cooley Architects, Inc. is committed to design which is environmentally responsive and promotes an improved quality of life by finding sustainable solutions which best meet its Clients’ objectives.
