Curved Timber: 6 Times Architects Bent Wood to Their Will

There are no perfectly straight lines in nature. Trees, with their rounded trunks and supple branches, are no exception but you wouldn’t know it by looking at most wood façades. The naturally sinuous qualities of wood are often lost as trees are milled into flat boards, to be used as cladding on rigidly rectilinear buildings. This collection, sourced from the Architizer database, features projects that take a different approach. These façades bend, twist and undulate to show us that architecture can be clad in wood without being so wooden.

所说的是，创造弯曲的木外墙更容易说。这是一个设计挑战，需要巧妙的细节和建筑师，工程师，制造商，木匠之间的密切合作，有时甚至是造船商。必发娱乐官方网站今天，这些不同的团队依赖于传统工艺和当代技术的婚姻，如参数造型软件和数控铣床，以创造越来越复杂的木材曲率。

ONDA RestaurantbyALLIANCE ARKITEKTER, Oslo, Norway

Wood siding byKebony

ONDA, the Spanish word for wave, is a fitting title for this seaside restaurant, located on Oslo’s Aker Brygge pier. Inspired by the movement of the water, the ribbon-like façade of glass and wood wraps around the building, framing views of the harbor and defining an undulating public space. The building’s organic form and sustainable wood cladding reflect the restaurant’s commitment to creating an all-natural dining experience. Both the façade and the surrounding deck are clad in Kebony, a wood product created by impregnating FSC-certified pine with furfuryl alcohol.

The alcohol, which is produced from a bio-based liquid, hardens the cell structure of the wood, creating a durable and maintenance-free finish without the need for oils or chemical treatments. As the Kebony ages it will naturally develop a silver patina, which is characteristic of many waterfront structures in Norway. In the architects’ words, the curved wood façade will “stand as an expression of our time and a proud reminder of our maritime traditions.”

Kamppi ChapelbyK2S, Helsinki, Finland

Kamppi Chapel, also known as The Chapel of Silence, sits like a large wooden bowl in Helskinki’s Narinkka Square. According to the architects, the building’s gentle curve directs visitors into the space while the wood cladding “shields them from the bustling city life outside.” To construct this rounded form, K2S turned to Finnish shipbuilders, Late-Rakenteet Oy, who produced a structure of tapered glulam ribs, and to the carpenters of Puupalvelu Rajala Oy, who milled the lumber for the project using CNC technology.

The exterior is clad in 1 3/8-inch-thick boards of locally-sourced spruce, which are finger-jointed together and notched into the curved ribs. The spruce was treated with pigmented Biowax, which will protect the surface from water while allowing the wood to age naturally over time. On the interior, the walls are finished in slightly thicker planks of oiled alder. The ceiling appears to float above this space, held apart from the walls by a perimeter skylight, which bathes the curves in natural light.

KildenbyALA Architects, Kristiansand, Kingdom of Norway

Under one timber roof the Kilden Performing Arts Centre unites three entities: The Agder Theater Company, The Kristiansand Symphony Orchestra and The Opera Sør. The undulating façade, clad in locally-sourced oak, invokes both the surrounding water and the hulls of nearby ships. In fact, Risør Trebåtbyggeri, a Norweigian shipbuilder, supplied the oak boards and was heavily involved in the construction process, along with several other companies: Trebyggeriet and Blumer-Lehmann, who produced a series of curved glulam beams for the structure, and Design-to-Production, who provided custom CNC-milling for the project.

Using digital modeling software, this team worked with the architects to devise a system wherein the oak cladding is notched into the glulam beams which, in turn, are supported by a steel frame. This complex structure continues, uninterrupted, into the interior of the building, where the oak becomes an acoustic ceiling for the foyer. Like a rising theater curtain, this warm and curvaceous canopy marks the transition from reality to fantasy. In contrast to the main façade, the sides of the building are clad in a sawtooth pattern of dark aluminum panels.

Interims AudimaxbyDeubzer König + Rimmel Architekten, Munich, Germany

This temporary lecture hall was built to accommodate a recent influx of students attending The Technical University of Munich. With a shoestring budget and a nine-month construction deadline, the architects opted for a simple, wood-framed structure, clad in rough-sawn spruce. All of the lumber for the project was supplied and installed by the carpenters of Merkle GmbH. This boxy construction is enlivened by the cladding’s irregular substructure, which causes the façade to ripple.

In contrast to the dark exterior, the interior is finished in untreated oriented strand boards, a subtle reminder of the building’s impermanence. Deubzer König + Rimmel Architekten’s design was the winning proposal in an open competition held by the university. The jury presiding over the contest lauded the projectin a statementwhich concluded: “This dark solitaire is a wooden building through and through. With its modulated shell, it shows new ways of using the sustainable building material — miles away from the cliché of the natural façade.”

Wood Siding byWood Newton

The Velodrome, a cycling stadium built for The 2012 Summer Olympic and Paralympic Games, rises in London’s Olympic Park like a great swell of timber. The elliptic façade, inspired by the wooden bicycle track at the center of the stadium, is clad in western red cedar, manufactured by timber specialist Wood Newton. A protective coating of Textrol oil enhances the cedar’s natural color and grain.

The ends of the boards are capped by aluminum fins, segmenting them into bays which better articulate the building’s curves. The cladding system features custom routed slots through which air can pass, allowing the entire stadium to be ventilated without mechanical means. Wood Newton also produced the timber cassette panels which make up the stadium’s double curved roof. These cassettes are supported by a steel cable net structure and finished in Kalzip standing-seam aluminum panels.

Wood siding supplied byWetset EnterprisesandKaster’s Kustom Cutting

一个北弯曲的木材设计在比一个人更多样地打破了商业发展的模具。建筑师雇用了许多可持续战略，如光伏屋顶板，超级绝缘的建筑包络和弯曲的遮蔽孔，以确保该项目比典型办公室开发更高的节能高达60％。建筑物在繁茂的木材中框架，并且通过radiustrack生产的冷成型钢组件可以实现外墙曲线。

The use of sustainable materials was a top priority for the architects and builders, who became intimately involved in the selection and production of the exterior cedar cladding. All of the planks were responsibly harvested, logged and milled by two local timber companies: Wetset Enterprises, which provided the bulk of the cedar, and Kaster’s Kustom Cutting, which supplemented the supply when necessary. The cedar was finished with two coats of TimberPro stain and a fire-retardant treatment, as required by local codes. You can learn more about the construction of these beautiful offices in the video above, produced by the project’s contractors.
