Finnish company Metsä Wood is known for pushing the envelope when it comes to building with wood. Their latest greenhouse dome is the largest to date – and it showcases the company’s innovative use of laminated veneer lumber as a sustainable alternative to commonly used building materials. The structure, named Dome of Visions, was designed by Atelier Kristoffer Tejlgaard as a way to explore green building.

The Dome of Visions 3.0 is the third project in a series of experiments that explore the idea of creating sustainable spaces within dome-shaped structures. It has a new system of curved wooden beams, composed of 21 mm strips of Kerto LVL (Laminated Veneer Lumber). This made it possible to minimize the amount of steel while achieving both a sleek and elegant grid construction.

Using curved wooden beams, the brackets for the dome’s supports were cut as stars in a five-millimeter steel plate. The custom-made Kerto beams made it possible to avoid the use of complicated and costly welded brackets used in previous versions.

“Wood as a building material has obvious advantages giving sustainability for the building industry. In principle, wood is a material that comes from a solar-powered factory,” said Kristoffer Tejlgaard, referring to the ability of trees to extract CO2 from the atmosphere and store it as carbon in their trunks, solely by means of solar energy.
