Our Collective Experience

Prior to founding Market Square Architects, the Partners of the firm spent the last two decades delivering a wide range of projects across the region and the nation.  While we build our new portfolio please see our list of some of the many clients we worked with and the projects we worked on during our time with other companies.  While pictures can say a thousand words, so too can the many clients that we have had the pleasure of working with.  We invite you to reach out to them and hear first-hand what it is like to work with us. In the meantime, please enjoy Market Square Architects’ significant and ever-growing list of projects in our online portfolio.

new_hampshire_fisher_cats_logo“Market Square has been a pleasure to work with throughout this project. They’ve helped redesign our ballpark into a state-of-the-art entertainment destination, and we couldn’t be happier with the results. Our fans continue to rave about our new tiki bar, music stage, and seating pavilion — it feels like they’ve been here for years. Market Square made it all happen, and we look forward to working with them again on our next project!”

Single Family Residential
Over the past twenty years, firm partners and staff members have participated in the successful delivery of numerous single-family residential projects across New England, the Mid-Atlantic, and the Midwest. These projects have ranged from small additions and local approval process management to large multi-million dollar ground-up construction. We currently have several projects on the boards including new single-family homes in Rye, NH and York, Maine and renovations to homes on the coast of Maine, Boston North Shore and in the Lakes Region of NH.
