The people behind the designs.
Market Square Architects PLLC was established in 2016 by Adam Wagner AIA and Robert Harbeson AIA, with a focus on providing great value and impeccable attention to design with every client we serve. Our headquarters are located in the heart of Downtown Portsmouth, NH and we manage projects across the region in both the residential and commercial sectors. In 2018 the firm acquired Allan Nutt Architects in Austin, Texas to better serve our clients in the Southern Region.
Market Square Architects is currently licensed to practice in 24 states, with more on the way. Our projects range from small renovations to complex multi-phased $50M ground-up projects and everything in between. No matter where you are, or how big your project may be, we provide excellent design services at fair and reasonable prices.
Design – Design is an integral component for any architecture firm. We focus on finding creative design solutions that meet the needs and the budget. We assist our clients in navigating the decision-making process so that decisions can be based on aesthetics, value and life cycle maintenance costs.
Deliver – Our blend of creative design and technical abilities sets us apart. Our wealth of experience navigating approvals, permitting, the construction process and representing the interests of our clients helps to ensure that a project is completed with the same focus and energy as when it begins.
Market Square Architects was started by two veteran architects who were looking to blend a big agency feel with a small town touch. Both spent many years working with top architecture and design firms and decided to bring their commitment to their work to a whole new level, founding what is now Market Square Architects, PLLC.
