Time off at the Fair

While the Olympics played out in Rio this past weekend, another kind competition took place under blue skies in Cornish, New Hampshire, at the annual fair. Cows and chickens, lambs, ponies, oxen and rabbits were on display as were the woodsman skills of men and women. (How long would it take you to chop down a tree? Can you throw an axe and hit a target?)
Summer fairs are a longstanding tradition in New England, the first being held in Londonderry, New Hampshire, in 1722. Cornish continues to place its emphasis on animals, and its dairy show is said to be the largest in New Hampshire and Vermont.
With a nod to the arts, it runs an annual fair poster contest, sponsors an artist in residence (Gary Hamel), and holds an art sale in the Town House.

Cock-a-doodle, who me?

Oxen await competition.   Pulling concrete for sport.

Cows of many colors; got lots of milk.

Glued, screwed, nailed, and foamed

Designing and building your own home is not an endeavor for the faint of heart. Large doses of courage, confidence and commitment come in handy. It helps, too, to be guided by a set of principles, a philosophy.

Aerial skills are required for this line of work.

After years of living in houses designed by other people (old and new) we longed for a house designed for the way we live. And so our design follows function. A carport near the door that leads to the kitchen for unloading groceries. A big mud room because there will be mud—and dirt and snow. An open layout of kitchen, dining, living areas, so whoever is cooking can feel connected to others. A kitchen with a big island (stainless steel) for prepping and socializing. A first-floor master suite (over 60, no explanation needed). A screened porch since some of the nicest days of summer are also the buggiest. Black flies don’t take vacation. Passive energy design because “the best kind of energy is the energy you don’t use.” Wood-burning stoves for those notoriously cold New Hampshire winters.

Once we had the layout refined and decided on timber frame construction for the center portion of the house, structural insulated panels (SIPs) were the natural choice for sheathing the frame and giving it a high R-value insulation. We could have chosen stick-frame construction (2 x 6s with insulation) for the side wings but decided to keep going with the panel construction. Simplicity is another principle we followed.

For the past two weeks, we’ve been watching the house go up as huge pre-assembled panels fly through the air (with the help of a crane and five workers) to be popped into place, glued, screwed, nailed, and foamed. Foard Panel of West Chesterfield, New Hampshire, is doing the skilled and professional work. The structural panels are sandwiches of oriented strand board on both sides of a foam core; 6.5 inches thick for the walls; 10.25 inches thick for the roof. Laminated wood splines are wedged between two panels and nailed to marry them. Huge screws are used to attach the panels to either timber frame or engineered wood posts and beams.

Door and window openings are made in the workshop.
Some of the advantages of panels over traditional stick framing include faster on-site construction, reduced construction debris, less waste due to factory, engineering of panels, and lifetime energy savings to heat or cool the structure.

Michigan architect Alden B. Dow (1904-1983), briefly apprenticed to Frank Lloyd Wright (Taliesin, summer 1933), is considered the inventor of the SIP (known earlier as the sandwich panel). Wright had used plywood and tar paper panels in his Usonian homes but neglected to add any insulation. Dow, very much an innovator, took off with the idea and incorporated an insulated core.

The longest screw is 13 inches long.

Doug and I agree with (and have applied, unwittingly) Dow’s design philosophy displayed in his Midland, Michigan, home: "Architecture is more than the front face of the building. It is the location of the building. It is the plan of the building. It is the construction of the building. It is the heating and cooling of the building. It is the furnishing of the building. It is the landscaping of the building. It is, in its entirety, the manifestation of wholesome living." Well said, Alden.

Factoid: Dow’s father’s manufacturing company, Dow Chemical, introduced Styrofoam products to the United States in 1954. Ray McIntire, a scientist employed Dow, is credited with the invention, which combines polystyrene beads with air.
