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."

High end architect specializing in making a house feel like home! I make people’s dream homes a reality. There is nothing more satisfying to me then improving the quality of life for my clients and giving them a house that they are able to make into their homes. I have been a licensed architect since 2015 and am currently registered in Rhode Island, Connecticut, New York, Maine and Massachusetts. With my NCARB certificate I am able, if necessary, to obtain reciprocal licensure throughout the country in a short time period. I am inspired by our local built environment, humble materials, classical building forms and traditional building details. I have a strong interest in the reinterpretation of classical building forms, blended with contemporary open floor plans. I have a stronger interest in helping to guide my clients to ways of improving the quality of their lives through adapting the built environment to meet their needs.

"He was pretty responsive, caring, look into our concerns, manage to work everything, willing to work on the plans."

I provide residential structural engineering services to both homeowners and home improvement contractors. These services include plan preparation, design of structural members, structural evaluations of existing buildings, review of plans prepared by others, design of sanitary systems and on site drainage systems if necessary. All work is done by me, a registered professional engineer in New York, and I also conduct inspections and evaluations.

"Was Awful. Measurment's were off. Plans were incomplete. After he measured the rooms, we had to remeasure the rooms ourselves and send them to him. I then had to go to his house to pick up the plans. I submitted the plans at which time I was told that I needed to get then done again by a professional. Held up the construction by several weeks. Save your money. Do not use Lou."

Custom Home Builders questions, answered by experts

The longest part of building a custom home is the design phase. It takes multiple professionals and a ton of work to bring your vision for your dream home to life while sticking to a homebuilding budget and also ensuring everything is built to code. Expect the design phase for a custom home build to take six months to a year.

Yes, professionals offer mantel and surround customization for aesthetic appeal.

Above all, the downside to building a new house is a longer timeline. You need several months to finish the build, depending on the supply chain and labor availability in the meantime. Building a home compared to buying one is also more expensive, both in the building process and when it comes to mortgage rates and property taxes.

While it’s never too early to start planning for a major home improvement project like a home addition, give yourself at least a month or two to plan and design your addition, find a contractor, and get the permits in order. For larger projects like a second-story addition that require designing with an architect, plan on three to four months of preparation.

Yes, a home builder should have a builder’s license and insurance. States have different requirements for builder’s licensing and certifications. Be sure to check our state licensing tool to review your local home builder licensing guidelines.

As you browse our pro listings, take note of the “Angi Certified” badge. Angi Certified businesses meet our standards for certification, which include:

  • The owner, principal, or relevant manager passed a criminal background check

  • Required to have applicable state and local licenses

  • Maintain an average star rating of 3.0 or better on our network, if they have at least one review

  • Paying to advertise their services

  • Meeting any other eligibility criteria required by Angi
