Bigwood by Olson Kundig - OBJEKT International

Bigwood

An entire glass wall swings upward to open this spacious retreat to the landscape of the American West – one of several inventive features incorporated by US firm Olson Kundig. The Bigwood Residence is tucked into a hillside in Sun Valley, a resort town in Idaho.

“When I first visited this site, the owner and I immediately had the idea for a building that seems to be emerging out of the landscape. The east end of the house is buried, while the two projecting west-facing wings have unobstructed 270-degree views of Bald Mountain, Griffin Butte, and Adams Gulch. The house takes advantage of all the site has to offer: sweeping landscape views, balanced with a sense of being underneath, within. I’m always trying to find the yin and yang of a place. Likewise, the two main sections have windows onto a central courtyard, and the pivot wall opens to face it as well. The idea was to create more intimate moments that would balance the big views.” – Tom Kundig

“The clients wanted a modern house that would feel authentic to the high desert mountain landscape. So it is rugged; the client calls the style “mountain industrial.” Everything that touches the earth is stone and board-formed concrete, and everything that projects out is steel and glass. The roof is made of corrugated weathered steel and slopes slightly. The wood finishes on the interior are intended to make the occupant feel warm and protected, in weather that can at times drop to minus 20 degrees.” – Tom Kundig

Iconic and Custom

Custom hardware and iconic furnishings are found throughout the house. A fourteen-foot-long dining room table — salvaged black walnut on a steel frame and oversized rollers — is designed to divide into two so half can be rolled onto the adjoining deck. Overhead, a pulley and solid steel counterweight raise two custom light fixtures to further open up the space. At the connecting bridge, the pivoting glass wall is counterbalanced overhead by a large steel weight that sits five feet above the roof; the hand-wheel’s crank is attached to an eight-foot-long screw. In the powder room, the faucet above the welded stainless steel sink basin is connected to a shower valve, creating a simple, one direction operation. The sleek design language is repeated in the shower.

There are patios under the cantilevered sections; it’s a two-for-one solution in which you get some shaded recreational space in the summer, and keep the building well above the snow line in the winter. The cantilevers are supported by masts that are also see-through fireplaces. The one supporting the main section is in fact two fireplaces: one indoors (in the great room above) and one outdoors (in the patio below). The wings are connected by a steel-and-glass bridge with a south-facing wall that pivots entirely open. It’s twenty-five feet long and counterbalanced overhead—the first time we’ve done that at this scale—by a large steel weight that sits five feet above the roof. The hand-wheel crank that operates it is attached to an eight-foot-long screw.
