Since its founding in 1996 by Ken Hayes, AIA, Hayes Group Architects has distinguished itself as a diverse design practice dedicated to solving client problems with innovative but practical architectural solutions.

At Hayes Group Architects, we believe design is an iterative process, ensuring that the solutions we create will accurately reflect our client’s core values, goals, and mission. Our architectural style is circumstantial, not predetermined, and responds to the nature of the site, the social and physical context, and to our client’s lifestyle, work style, and aesthetic disposition.

While this philosophy has earned us awards from the design community, its true value is in how it enables us to create solutions that are as diverse in physical response as they are in purpose, and that reflect each client’s personality. And because we believe the best solutions are custom-tailored to our client’s needs, we rigorously manage the size of our firm to provide a personal but scalable experience to all of our clients, no matter how large – or small – their projects may be. Not only does this make it possible for one of the principals to be involved in every project we undertake, but it also leverages the depth and breadth of our staff’s experience and vision, yielding designs of uncompromising quality.

We offer a broad range of architectural and design services tailored to each of our client’s individual needs. This range includes programming/needs surveying, site evaluation, zoning/feasibility analysis, architectural design and documentation, entitlement consulting and more. We also routinely collaborate with a deep pool of highly-regarded engineers, investors, makers and builders who are time-tested and purpose-driven to execute complex projects with diverse stakeholders. The teams we assemble are comfortable operating within conventional and alternative models of project delivery, including traditional design-bid-build, design-build, integrated project delivery (IPD), target pricing and early contractor involvement (ECI).

Our interior design studios provide comprehensive services for buildings we and others have designed including visioning, space planning, interior architectural design, furniture selection and procurement to creatively adapt the interior environment to our client’s needs and the building’s inherent attributes and amenities.
