Swedish designer Martin Thübeck has constructed a furniture range with "infinite building possibilities" using reclaimed wood from a local birch sawmill. 
Called Betula, the collection consists of a chair and dresser with frames made entirely from timber slats connected using the same joint.
The Betula collection contains a dresser (top image) and a chair (above)
Thübeck created the collection after learning that large amounts of birch, which had already been refined and formed into uniform slats, was discarded because it was deemed unfit for sale.
He aimed to do as little as possible to these discarded pieces of timber to create useable furniture.
Both the dresser and the chair are made from sawmill waste
"The owner of the sawmill explained that roughly 70 per cent of all the logs that come to the facility is considered waste and gets burned," Thübeck told Dezeen. "This inspired the idea to explore how the least amount of work could affect the value of the discarded material the most," he continued.
"So I developed a simple joint that could turn the waste into a building block, where all pieces have the same shape, creating infinite building possibilities."

The joint was created by milling a central cut into both ends of the slat to create a form that acts like the groove part of a tongue and groove joint.
Since this cut is exactly as wide as the slats, it allows a...
