Todd O'Connell Architect, P.C.
Todd O'Connell Architect, P.C.
We are a reputable architectural design company that specializes in a variety of exterior and interior design. We take pride in our ability to exceed expectations in all aspects of business. We look forward to building long-term relationships with our clients and guarantee your satisfaction.
"I am recommending Todd O'Connell Architect for anyone in need of a new home design or remodel. The design of our house was fantastic and the price was fair. Our project was a typical one - to dormer a cape cod. The new design of the house overall was great, but to provide some transparency: there was one issue with initial design which showed that we needed drywell on our property. This was a major oversight and actually not required according to town rules and could have been very costly- but our GC caught the mistake before the plans were submitted to the town. Also, communication could have been better- Toddâ s team required phone calls because they werenâ t as responsive via email, which made things tough because I didnâ t always have time for a phone call. That said, our project required a variance and Todd was able to represent us and easily get us past the finish line (the project is very typical in New England). All in all, we are satisfied with the final design of our house and constantly receive compliments from our friends, family, and neighbors, and it has a lot to do with the design that Todd & team came up with, so I would use Todd & Team again but make sure that we also have a good GC."
