"Building beautiful custom homes with efficiency and affordability."

"Best builder in the Berkshires" - Marja Tepper  

“We commissioned James Weber to be the General Contractor on a “Re-Construction project..”  We came to Jim with a big dream and a mediocre budget. Jim came forward and stewarded our project as, we believe, no other G.C could have. Jim Weber and his J.W Construction crew created an extraordinary home for us that not only is a dwelling but an “Arts and Crafts” style work of art. His craftsmanship is unsurpassed, his artistic eye for design and detail, outstanding….and he was able to keep the project moving in a timely fashion and within a reasonable budget.”                                                        -Cynthia and Jeff Caminiti, Hurlburt Road Great Barrington, MA

“Jim, thank you so much for sharing your skills, talent and patience with us! We really appreciate how much you have done to make this house special and how much of yourself you put into your work. …”                                                                       -Debra and Mark Hoffman, Becket MA

“Hi Jim, we are here at the house on Stockbridge Bowl and first of all I want to say that it looks really incredible! I cannot believe that it is much better than I could have anticipated. The bathroom, bedroom renovation is amazing! The custom built glass wall that match the original architecture is perfect…I am so glad we did that, you were so right about the details. The design and workmanship is impeccable, thank you so much..”

In have always been very satisfied with the quality of his work, as well as impressed by his grasp of the organizational aspects of any construction project which he has undertaken. I offer an excellent reference on behalf of Jim..”

“Jim built my house at 48 High St, West Stockbridge Ma.  He also acted as General Contractor, and was very professional, returned calls promptly, managed the various crews very well, showed up on time, and was a great help with design ideas, very innovative and practical minded. He was a pleasure to be around, his joyful spirit resonated in all aspects of building..”

-Deb Koffman, West Stockbridge MA

“I highly, confidently and enthusiastically recommend Mr. Weber.  Jim became the ongoing designer on the job, as well as a competent overseer of one of the most pleasant and hardworking crews we could have wanted at the School…..For an overview, the scope of Jim’s work at Interlaken included: demolition, large partition removals; building and furnishing new offices consistent with historic style and tone of the building—….restoration of the historic theater stage and surround; addressing of sound attenuation;moving and reinstallation of heavy commercial equipment; design and installation of new staff kitchen;and complete handling of all installation, painting, wiring, and plumbing needs…….perhaps most encouraging of all was, that not only did the work get done, done beautifully and done on budget, but throughout, Jim’s positive, professional, service oriented demeanor, never wavered….”
