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."

Custom Home Builders questions, answered by experts

Craftsman-style homes are predominantly found in the Western United States, specifically in Southern California, where the style originated. Since the climate was mild and there was access to plenty of natural resources, Southern California became a hub for this style at its inception. That being said, if you consult with an architect near you, you can have a Craftsman-style home anywhere.

A custom home is one that you design from the ground up, allowing you to customize everything from the square footage to the interior layout to all of the materials used. A spec home is one that a builder has designed and gotten approvals for. Spec homes may give you some limited options for the layout and materials, but most of the build is pre-set. Custom homes cost more and take longer to build.

Custom homes can take an average of 18 months to build, mainly due to the lengthy design process, and most projects take somewhere between 12 and 24 months. When you work with the right custom home builders near you, they can help you map the road ahead and understand what can speed up or delay the timeline. Choosing locally available materials, for example, can speed things up without losing that customized touch.

Yes, modular homes offer a wide range of customization options for layout, finishes, and features.

Modular homes last an average of between 50 and 75 years, and high-quality modular homes can last for 100 years with proper maintenance. For comparison, a standard home lasts 50 to 100 years and can push to 150 or longer with good maintenance. Modular homes provide better long-term value in that they are significantly more affordable and can last almost as long, but some buyers are wary of modular home longevity, so the actual value if you sell could be lower.
