/ About


“Your design should be as unique your individual dream and the needs it is intended to accommodate. We start each project by establishing a true meeting of the minds to gain an understanding of your goals, and then turn ideas into reality by applying unmatched design talent and up-to-date knowledge of current trends and the latest offerings in materials and finishings. We welcome you to challenge us with your most imaginative project and consider boundary-pushing projects the best way to keep us on the forefront of excellence in design.”

“Our service is unique in that it must produce a product capable of both inspiration and performance. Our extensive experience with clients of all walks of life and across multiple design categories and building uses has afforded us the rare skill of shaping a beautiful vision into something livable and functional that stands the test of time. Our ability to provide personal attention necessary to understand and anticipate your needs results in the design of a structure that will add ease and fluidity to whatever activities are to take place between its walls.”

“As an architectural firm with over 35 years of experience designing structures ranging in size from 1,000 to over 35,000 square feet and spanning custom homes, multi-family residences, commercial storefronts, mixed-use community buildings, and more, PAI has mastered the ability to deliver personal attention, flexibility in responding to each design criteria, and precise technical support from project start to finish. Don Purser, chief architect, will share his knowledge and wisdom to turn your unique ideas and dreams into reality.”

“The achievement of excellence is rarely a happy accident. It is more likely the product of inspiration born of experience, coupled with exhaustive research and systematic problem solving”
