A young couple with children asked Charles Rose Architects to design a “contemporary Polynesian hut” for their property southwest of Boston on the Charles River.

The design called for indoor and outdoor sitting and dining areas; kitchenette; stainless steel outdoor shower; bath/changing area; 1,500 SF deck with in-ground hot tub; and a fire pit with built-in seating. The architect carved out one corner, creating a covered, but open and airy, outdoor lounging area.

Everyone agreed that the new pool house should be wood construction — primarily to match the look and feel of an earlier project the architects designed for the clients, a wood-clad “play barn” with two large rooms, divided by an outdoor space framing views of an adjacent pond. That’s where Bensonwood came in.

Our timberframer C.J. Brehio was the job captain, and did a masterful job executing complex compound joinery. Custom concealed steel connections were also used throughout the building. Western red cedar lends rich, warm hues from exposed beams, custom doors and millwork.

Pool-Centric Vision Posed Technical Challenges

_DSC7399.1.72

Faced with a significant technical challenge, Alfandre Architecture, PC and its construction company, EcoBuilders Inc., teamed up with Bensonwood to fabricate and install the large-span glulam timbers and insulated shell of this spectacular 6,000 SF timbered dream house — all built around a large 2,000 SF indoor pool — for their client, a retired couple in Putnam County, NY.

pool house living areaThe challenges included engineering the long timber spans of the pool room, humidity control and the sensitivity of the rocky build site, to name a few. Here, Bensonwood’s expertise in timber engineering, off-site fabrication of panelized assemblies and rapid on-site installation was instrumental in realizing the ambitious project with minimal disruption to the ecology of the home site.

The house, recessed into the bedrock of its 15-acre site, was designed by architect Rick Alfandre to complement its natural setting, with the pool room both anchoring the design and providing the homeowners with the physical, social and emotional benefits of their daily one-hour swim. To add to the ambiance, the light-drenched, four-bedroom, five-bath home has over 70 triple-glazed windows to draw the surrounding landscape into its interior.

From this project, Bensonwood went on to contribute the timberframe and roof panels for Alfandre Architecture’s offices across the Hudson River in New Paltz, NY, for which Alfandre is seeking LEED Gold certification.

Bensonwood Associate’s Visionary Design on Display at Boston Society of Architects Exhibit

urban timber logo

Urban Timber: From Seed to City,” a new exhibit at the Boston Society of Architects’ Gallery Space, celebrates wood as a natural and sensible building material for cities, while highlighting wood’s adaptability, versatility and extraordinary technical qualities. It also highlights some innovative thinking going on at Bensonwood.

Included on display at the BSA Space — and the result of an open competition — are four winning projects proposed by emerging architects featuring innovative structural uses of timber.

The winners collaborated with mentor architects, engineers and material suppliers to develop and realize their installations in the gallery. Each piece in the exhibit is an art project — and would look right at home in any modern art gallery — but is trying to prove a design theory.

Two of the four design installations in the exhibition involve Bensonwood associates. The first, “Four Corners” by Yasmin Vobis and Aaron Forrest, enlisted Bensonwood chief structural engineer Chris Carbone as a mentor. The Four Corners installation turns the traditional timberframed New England barn inside out using cross-laminated timber.

The second, Bensonwood Designer  Tim Olson’s dynamic “Coopered Column,” weighs about 3,000 pounds and consists of 118 timber pieces and over 250 screws. Titled “coopered” because it borrows from the design of a barrel; the interlocking timbers act like staves, and a belt of screws holding it together mimic the metal hoop of a barrel or other wooden vessel made by craftsmen known as coopers.

Olson’s bowl-like installation is called a column because a cylindrical support was his original design, a wooden structure that could handle the weight of a skyscraper. He flattened the column into a bowl shape to demonstrate how the design could handle stresses necessary to support a building. You can listen to a recent NHPR story on Tim’s installation.

The exhibit also explores how using wood in mid-rise buildings can combat climate change and underscores wood’s potential as the need for high-performance, low environmental impact structures continues to increase in our urban centers.

P1000928In addition to exploring wood technology and recent innovations in the array of engineered timber available to architects and engineers, the Urban Timber exhibit dispels common myths associated with building in timber, such as the notion that heavy timber is not sufficiently fire resistant. In some instances, engineered wood retains its integrity even better than steel. Cross Laminated Timber (CLT), for example, has a higher resistance to fire because of its thickness since the outer layers, when charred, protect the inner layers, just as a large-diameter tree does in a forest fire.

While the perception of wood in America as a lesser building material endures, Yugon Kim, founding owner/partner of IKD and co-curator of the BSA exhibit,  believes that Urban Timber: From Seed to City will show that the use of timber as the primary structure in mid-rise building construction in Europe proves there is a new future for wood buildings.

Urban use of heavy timber has long been an interest here at Bensonwood. In 2007, Bensonwood and Unity Homes founder Tedd Benson was a leader of the UMass Amherst Wood Structures Symposium that explored technological advances in green buildings, as well as digital fabrication with wood and engineered wood products. Organized by the university’s Building Materials and Wood Technology program, the event highlighted new advances in contemporary wood architecture and presaged the current interest in building high-rises with wood. Currently, the tallest wooden buildings are only around 100 feet tall, but constructing much taller timber buildings is now a realistic idea.

In recent years, the technical advances that Bensonwood and Unity Homes have helped develop have given rise to a broad range of process innovations, such as CNC milling and off-site assembly, as well as engineered-wood products with superior performance qualities, such as the glulams (glued, laminated timber) and CLTs used in nearly all of our projects for their strength, flexibility and reliability.

Thanks to novel composites and engineered wood products, such as glulam beams and CLTs, several multistory buildings have already been erected around the world with timber skeletons, and plans for taller buildings are in the works.

Urban timber proponents have been making a larger argument to the building industry and to policy makers that to build cities with a lower environmental impact, wood is not just promising but necessary. It’s a plentiful resource that grows back relatively quickly, and even pulls carbon out of the atmosphere during its life cycle.

Architect Michael Green, a passionate advocate for building wood high-rises,said in a recent TED Talk, “Steel represents about three percent of man’s greenhouse emissions, and concrete is over five percent.” He estimates that every 20-story building made out of wood instead of steel or concrete saves around 4,300 tons of carbon, equal to around 900 cars removed from the road in a year.

There are still some major environmental issues to tackle, of course, such as how greatly increased timber harvesting would affect our ecosystem. However, the USDA recently announced a major initiative to promote innovative, sustainable wood building materials for environmental protection and job creation.

Bensonwood Featured in “The New Net Zero” by William Maclay

the new net zeroThe New Net Zero: Leading-Edge Design and Construction of Homes and Buildings for a Renewable Energy Future

Bensonwood is featured prominently in a new book on Net Zero building by renowned architect William Maclay. We collaborated with Maclay Architects as a member of the team which designed and built the award-winning net-zero Bosarge Family Education Center at the Coastal Maine Botanical Gardens. The LEED Platinum-certified center was Maine’s first net-zero institutional building.

The new threshold for green building is not just low energy, it is net-zero energy, and in The New Net Zero, sustainable architect William Maclay charts the path for designers and builders interested in exploring green design’s new frontier—net-zero energy structures generating as much energy as they use while remaining carbon neutral.

Since traditional American buildings account for roughly 40 percent of our total fossil energy use, the significance of net-zero building is growing increasingly important—among designers interested in addressing climate change as well as homeowners concerned about energy efficiency and long-term savings.

Maclay, an award-winning net-zero designer whose buildings have achieved high-performance goals at affordable costs, makes the case for a net-zero future; explains net-zero building metrics, integrated design practices, and renewable energy options; and shares his lessons learned on net-zero teambuilding with like-minded companies such as Bensonwood.

The comprehensive overview is accompanied by several case studies, which include institutional buildings such as the Bosarge Family Education Center, commercial projects, and residences.  Both new-building and renovation projects are covered in detail. Unity Homes is profiled in the book, as is our multi-layered Open-Built® system.

The New Net Zero is geared toward professionals studying net-zero design, but is also suitable for laypersons seeking inspiration and strategies for beautiful and renewably powered net-zero options.

On the Boards: Cape Cod Pool House

cape cod pool house

In keeping with this month’s “Everyone into the Pool” theme, here is a charming little pool house we are helping fabricate on Cape Cod.

Designed by Rebecca Elsy Ribeiro of D. Michael Collins, Architects, the energy-efficient building features classic colonial carriage house styling with cupola and a sheltered overhang.

Bensonwood is crafting the timberframe, insulated wall and roof panels, and installing the Marvin Ultimate windows and a Marvin outswing bifold door. The timberframe consists of Douglas fir glulam timbers for the main structure and for the exterior timbers​.

Kenneth Vona Construction, a company that very much shares Bensonwood’s values, will be the builder. KVC is not only one of New England’s oldest and most respected custom builders, it is also one of the greenest.

Most of the firm’s projects are located in Massachusetts, but they also have projects in Maine, New Hampshire, Vermont, New York, Colorado, Florida and the Caribbean.

We’ll profile more design-build collaborations with D. Michael Collins, Architects and Kenneth Vona Construction in the months ahead.

Our Building Systems Flawless in 3rd Party Inspection

2014.01.16_Panel shop (25) - Copy Four times a year, TR Arnold, a respected third-party “in-plant inspection agency,” or IPIA, is authorized by us to conduct unannounced inspections at our Blackjack Crossing production facilities. In voluntarily submitting to TR Arnold’s findings, our intention is to ensure that construction standards (state & local code, as well as our own stringent standards) are consistently adhered to.TR Arnold

Essentially, TRA inspectors go through each of our work stations inspecting up to 120 certification elements. As part of this quality control process, TRA inspectors are authorized to, “…reject non-compliant units, to withhold labels and to inspect all finished units produced and labeled prior to a unit found deficient and subsequent to the last unit inspected at the station where the deficiency occurred.”

One such audit has just concluded, and we’re pleased to report that of the many assemblies inspected, no non-conformance issues were discovered and we were found to be in complete compliance.

According to Building Systems specialist, Scott Bosworth, “This is really a big deal because of our building techniques compared to other, very different kinds of prefab home builders. For example, with “Double-Wide” manufactured homes that travel down the highway in halves, there are only two certificates required: one for the left side of the house, and one for the right side. With our many panelized assemblies (that are later raised at the build site), there are 120 or more certification elements that can be inspected prior their leaving our production facilities.”2014.02.07_Panel shop (8)

As Scott elaborates, “And because of the kind of closed-panel, or closed-cavity assemblies we fabricate offsite, building inspectors at the home site appreciate seeing certifications created by independent, in-plant inspectors who have seen the panels come together at the point of manufacture. Therefore, getting a full compliance report from a third-party administrator is huge,” adding, “A perfect score from a company like TR Arnold not only helps affirm our own quality control efforts, but in some cases, having the certificate can also help reassure a local on-site building inspector regarding enclosed areas he or she cannot readily see into.”
2014.02.07_Panel shop (2) - Copy
According to Bensonwood/Unity Homes production head, Kevin Bittenbender, who is in charge of compliance control and was instrumental in setting up independent plant oversight, “We’ve been building to the highest quality standards for years. It’s just what we do. It wasn’t much of a change in our process, or product, to meet TR Arnold’s standards. We simply had to clearly explain and document our product, and how we work. Our standards are higher than what is needed for code, and receiving positive results from their inspections is a nice confirmation that we are successfully building to the highest standards in the industry.”
