Swedish studio White Arkitekter has completed Observation Tower Kärven, which is constructed from a network of timber beams resembling "a bundle of twisted straws".
Situated within a nature reserve in Getterön, the 12-metre-tall and seven-metre-wide tower by White Arkitekter has a hyperboloid structure composed of 140 beams combined with metal rings.

White Arkitekter described Observation Tower Kärven's design as having "a visually striking simplicity reminiscent of a bundle of twisted straws".
Developed using parametric modelling and calculation software, it aims to place its construction at centre stage.
The tower is composed of a network of timber beams and metal "Observation Tower Kärven's concept has required an understanding from both architect and structural engineer of each other's disciplines," said lead architect Lukas Nordström.
"This has resulted in a design where it is impossible to say where architecture ends and construction begins."
"By starting with a supporting construction principle and then creating architecture from it instead of the other way around, we had a logic from day one," he added. "We never had to compromise to force it into the architectural form afterwards."
