We are a single source for Integrated modular solutions and project delivery. We serve the multi-family, retail, commercial, hospitality,

and healthcare markets throughout the Northeast. Wesbuilt Modular also serves the wholesale segment of the single-family market for mixed use, niche and resort, build to rent, and adult community projects.  Permanent commercial modular buildings may be Type V (wood frame, combustible) or Type II (steel, concrete, non-combustible).


We currently provide commercial modular construction services to New York, New Jersey, Connecticut, Rhode Island, Massachusetts,

New Hampshire, and Vermont. We are always expanding our network and service area and will consider projects for clients outside

our current service area.


Commercial modular construction is quickly becoming a preferred construction delivery method due to its inherent “green” construction methods, design flexibility, speed of delivery, quality of construction, and its ability to shorten the construction cycle and help control costs. 


Our History

In 1986, Kacy Caviston built his first new home Northwest of Boston. In 1987, he was joined by his brother Jack, and together they founded Newtowne Development to develop land and build numerous new homes and neighborhoods. In 1997, Kacy and Jack Caviston founded Rolling Meadow Construction, Inc. after years of running this traditional development company. 


Shortages of land and labor, and increased obstacles in the permitting process made them question what future there was for small builders in this changing industry. They decided to combine their years of construction experience with modern technology now available to the construction industry. They chose to become one of the few builders abandoning conventional site building to embrace a new systems built approach to building.

Rolling Meadow Construction, Inc. was formed as a new, unique type of construction company specializing in custom designed and built modular homes and additions. They partnered with a select few of New England’s leading manufacturers of modular homes.


In 2012, after his brother became ill and passed away, Kacy transformed the company to a new type of construction company, Commercial Modular Construction Services, dedicated to providing construction for permanent commercial modular structures.


In July 2021, Wesbuilt acquired Commercial Modular Construction to expand its business into the modular industry. Wesbuilt Modular, LLC specializes in the modular construction of apartments, townhouses, condominiums, hotels, dormitories, niche residential, and commercial buildings throughout New Jersey, New York and New England. Services include site analysis, design, building systems consulting, project supervision, project management and construction management.
