JB Robbie Builders is a Duxbury custom home builder run by Jack Robbie — full new construction, additions, and whole-house renovations across the South Shore and Cape Cod, plus green building, framing, and site planning per its Houzz listing. Several of its reviews refer to the same team under an earlier name, Cedar Point Properties, before the company became JB Robbie Builders in 2018. The written record here is a real one, but it's an old one — ten reviews across Houzz and Google, all from 2013 to 2020, with nothing published since. What repeats across those years is precise, hands-on design problem-solving: in a 2020 Houzz review, a homeowner described Jack working through a last-minute ceiling-height adjustment, a stairwell redesign to ease the pitch of the stairs, and a way to tuck away attic access — the kind of on-the-fly fixes a design-build owner is positioned to make. An architectural designer who worked with the firm on multiple projects, in a 2017 review, praised how carefully the team reviewed plans and coordinated in the field to protect the design intent. Repeat clients show up often: one family hired Jack for a primary residence in 2010 and, years later, an addition to a second home, per a 2017 review; another worked with him on two separate full home builds, both finished on time and under budget, per a 2013 review. There's no negative signal in the record — no complaints, no government actions, and a BBB A+ grade — but the flip side of that clean sheet is that it's thin and old: with only 10 total written reviews and none in the past several years, it's worth asking for recent references directly. JB Robbie Builders is a solid option for a custom new-construction home or a substantial addition on the South Shore or Cape Cod, particularly for someone who wants close, hands-on design involvement from the builder — just confirm current availability and recent project references given how dated the public record is.

“When Jack and Jennifer Robbie, owners of JB Robbie Builders in Duxbury, decided to make their home in Harwich Port their permanent residence, the consideration of how to accommodate, incorporate, and enjoy the entire family—which now includes the growing future of three adult children—prompted visions of time spent together.”
Jack did such a beautiful job with our house. He was wonderful to collaborate with, and I felt confident knowing he had both the design sense and the experience to keep me from making any bad decisions along the way. Whenever I was concerned about something, he'd calmly come up with a solution (to mention just a few: a last-minute ceiling height adjustment; a stairwell redesign to make the stairs less steep; an idea for tucking away the attic access...). He helped problem-solve a multitude of practical details that hadn't been factored in. His patience and vision are amazing, and he always quickly understood whatever random design point I was obsessing over. (I think we spent a good hour figuring out where to center the kitchen island). It's our hope that Jack will work with us again on another future home!
We have done several projects over the years and our last two home builds have been with JB Robbie Builders. They are the best team our family has ever worked with. They came in right on budget and on the time. The quality and craftsmanship was amazing. I would highly recommend using Jack and his team. He builds beautiful homes.
Beutiful project!!
I am an architectural designer. I have worked with Jack, Jennifer and their team on multiple projects. Their attention to detail is excellent. If there is question that comes up in the field they are quick to collaborate and see what the best direction might be to maintain the design intent. They spend time to review the plans carefully and thoughtfully consider the needs of the client, as well as, understanding the building they are constructing before they are in the field. I would not hesitate to recommend them to any of my clients.
We've had the pleasure of working with Jack Robbie to build our home and most recently our carriage house. He has been a true professional and we would recommend him highly.
