1972-01B&B: Before Benson Woodworking Company (BWC) and Bensonwood, was B&B, for Benson & Benson, (Tedd Benson and brother, Steve). Together, the Benson brothers start out doing renovation, remodeling, and cabinet making—jobs other builders choose not to do. Later, they start disassembling falling down timberframe structures for clients in exchange for the materials. Steve Benson dies tragically in 1974, and B&B later becomes the Benson Woodworking Company.


1973-01 Tedd Builds woodworking shop in Alstead. Lacking money for materials or labor, Tedd builds a 5,000 SF woodworking shop out of recycled timberframe barns and silos. The woodworking shop, with its simple but strong timberframe joinery, gives Tedd the confidence to move forward with more sophisticated forms of timberframing.


smith The Smith House/ First use of prefabrication. Tedd works with friend, Mike Burke to build a new stud-built house with a timbered French country kitchen and dining area. He elects to prefabricate the construction elements in his newly finished woodworking shop for the added control and precision it allows. This seminal project cements Tedd’s early belief in the advantages of off-site fabrication.


The Taft House/ First full timberframe building/ First BWC house built from “foundation to furniture.” Tedd and Dave Bryant build what the Concord Monitor refers to at the time as “…the first full timberframe house built in NH in over 60 years.” From there, Tedd and his dedicated craftsmen go on to create the home’s exterior & interior doors, stairway, cabinets, built-ins, paneling, moldings and furniture—all in the new Alstead Woodworking Shop. From this influential project, the importance of control and influence on finishes is realized. This “Green & Green” holistic ethic, arising out of the Arts and Crafts movement, continues to be part of the DNA of the company and informs the way all projects are approached.


Tedd realizes the potential applications for residential structural insulated panels (SIPs) after seeing aluminum-skinned insulating panels at a walk-in freezer manufacturer.


1979-01 Tedd Benson (with Jim Gruber) publishes first book, Building the Timber Frame House: The Revival of a Forgotten Craft (Scribner’s Sons, 1980; Simon & Schuster,1995). Instrumental in the revival of this centuries-old form of building with heavy timber, the book serves as a manual for builders and designers of timber frame homes. Today, it’s still considered the bible by timber frame enthusiasts around the world.


The Simsbury House/ First stress skin panels. Tedd and Amos Winter develop some of the first stress-skin panels for residential use. With the timberframe providing for the structural loads, the two develop a way to incorporate Bun stock, a rigid foam insulating material, to create a structurally uncompromised, built-up enclosure system. The company continues to produce its own closed panel walls, though with greener materials and greater sophistication than in this early prototype.


Masahiko Ishikawa brings Japanese temple building skills, infusing Bensonwood employees with knowledge about fashioning ultra-precise timber frame connections and ancient techniques of making compound joinery.

Tedd and a small group of timber framers form the Timber Framers Guild of North America knowing that the timber frame revival needed a vital, well-connected industry to establish a forum for learning and standards.


Rees Acheson joins company. He has a huge impact on company capabilities. Tedd hires Rees to fabricate a portable mortising machine, making it possible to rapidly create timber frame joints with great precision. It is still use today on the largest timbers.


Company purchases early computer for $6,000 and asks Rees Acheson for a whole new strategy for mastering complex compound joinery. Rees develops a trigonometry program with AutoCad output of Hawkindale angles, thus creating specialized software where none existed before. This allows timber framers to layout and cut the many compound angles in hip and valley roof structures.




Tedd hires Ben Brungraber, Ph.D./ Fine Engineered Timber Frame Structures. Bensonwood becomes the first company to have a professional engineer dedicated to timber frame design and engineering. Ben elevates the company’s engineered timber frames to new levels, proving to building inspectors the efficacy of his sophisticated compression and tension joinery. From Ben’s extraordinary talent and experience begins the company’s legacy of timber frames as fine engineered structures. Today, Bensonwood has a growing team of dedicated engineers and architects involved in all aspects of wood and metal joinery.


Bensonwood first featured on PBS Television’s This Old House.


Brian Smeltz hired. Lucky for Bensonwood, Ben Brungraber brings Brian Smeltz into the company. He is active in all company operations. A Renaissance man and Jack-of-all-trades, Brian proves to be an excellent timber framer, artist, designer, teacher, salesman and project manager. His enthusiasm and creativity leave an indelible mark on the company.


Bensonwood develops spline joinery to strengthen timberframe connections and allow for more varied timber design, while increasing the load capacities of the structure.




Tedd publishes his second book, The Timber-Frame Home: Design, Construction, Finishing (Taunton Press), providing a comprehensive guide to building a timber framed home.

Boris Noel Interns/ Begins long line of talented interns. Unlike many tradespeople in the United States, those in the European and Asian building trades are highly educated and revered for their mastery. Hungry for outside knowledge, Benson Woodworking Company invites these interns from abroad to simultaneously learn and share the skills of master craftsmen. Collectively, these interns from countries such as France, Germany, Switzerland and Japan bring a wealth of information to the company’s growing bank of knowledge.


Tedd creates Open-Built®, By merging the best thinking of open building proponents like John Habraken and Stewart Brand with his own concepts, Tedd develops a practical, digitally-based design, fabrication and construction system that revolutionizes how homes are designed and built. Open-Built allows for the disentanglement of mechanical systems from the structure of the house and organizes them for more efficient installation and long-term access. With Open-Built, Bensonwood designers electronically catalogue every design element they create. The 3D Open-Built grid system allows existing design elements to be quickly and easily adapted to any new home design.


alexandria009 Bensonwood works with the Alexandria Seaport Foundation to construct a boat-building shop/classroom for at-risk youth. Through the building and use of wooden boats, full-time apprentices earn their GED and prepare for a career in the building trades. The classroom is a full timberframe built on a re-purposed barge, our first floating frame.
