Our StoryBack to Top

Founded more than 40 years ago, CHA Architecture (formerly PDT Architects) provides architectural design that is rooted in community ideals and responsive to the landscape and local aesthetic. Our people thrive on collaboration, working as part of project team, listening to our clients’ needs, and concentrating on modern design.

CHA Architecture is aligned with the CHA Consulting, Inc., a multi-disciplined engineering consulting firm, with a shared aspiration to responsibly improve the world we live in. As part of the CHA team, we are supported by more than 1,000 technical professionals throughout the United States and Canada, providing a national platform to combine art and science to rethink, refine and reshape the built environment. Together with the large, technically diverse CHA team, we eagerly bring our creative skills to a broad array of projects in markets and geographies across the nation.

The tools may have changed over the past 40 years, the office has grown, and we have many new colleagues to collaborate with, but the ideas and creative energy persist and overflow. Our foundation remains clear — to create high-quality, collaborative designs that stress innovation grounded in careful listening to our clients' functional needs.

Our ProcessBack to Top

CHA Architecture offers a collaborative approach. We recognize that our clients know their business, and we see them as partners in the successful development of a project. We work alongside every level of stakeholder to understand a project.

CHA Architecture provides leadership and direction by guiding our clients through a design process that’s right-sized for each project. The process begins with defining the problem and understanding the goals while keeping in mind the realities of budget and schedule. The shared vision and goals become an important measure of the project’s success.

CHA Architecture delivers solutions that are flexible, creative and beautiful. Our building designs exemplify sustainable solutions grounded in building science with special attention to space, light, color and texture.

Our clients are sometimes surprised at our initial questions. As one client put it, “I came to the first meeting expecting to talk about where to put the walls, and we spent the entire time talking about how my company sees itself in the future of my industry.”

We tailor each process to your vision of your future. We gather abundant information using design charrettes, interviews, workshops, staff meetings, competitor benchmarking, and more. We start to design only after we know what the client is about and what they need, which has led to many success stories:

  • At a private school, a series of workshops attended by trustees, administrators, teachers, parents, and students channeled the energy from a preconceived auditorium renovation to a much-needed middle school project.
  • For a healthcare provider, a series of interviews and meetings became a tool for the client to address issues typically part of a strategic business plan, which then altered the space needs and organization of the building.
  • At a multi-location HMO, a transactional analysis allowed the organization to better express its philosophical approach to healthcare in the relationship of the patients and medical providers.

Think of our process as having an architect within your organization who understands you well enough to create an environment tailored to your culture and your specific organizational needs.
