"It may sound a bit crazy, but all I'm doing is changing the point in a tree's life at which I decide what its going to be," he explains. Based at Brunel University, High Wycombe, Mr Cattle has begun a living design experiment by planting 40 saplings arranged in various jigs designed to control the shape and grafting of the young trees. "I expect to get usable table and stool frames within about three to four years," he predicts.
If you think this is rather too long to wait for a piece of furniture, then you might have forgotten what any wooden article relies on: "If you compare the time spent growing perfectly straight trees ready for processing and making a conventional piece of furniture, my idea will be considerably quicker."
Tree species that grow rapidly, are flexible and graft easily are likely to work best. Mr Cattle has planted sycamore, maple, alder, cherry and beech and his experiment will determine which species will be the most suitable. The best time to harvest the crop of furniture is when the sap is down - the piece would then need to dry out before finishing.
Mr Cattle points out that his chair and table frames will be stronger than conventional furniture because the grain follows the shapes and because all the joints, rather than being stuck together, are formed through natural growth. But apart from functional advantages he also sees new design possibilities: "The opportunities are intriguing. I will be able to get shapes and angles that would be difficult and expensive to machine. The only real restrictions are in the size of pieces: large items would take too long to grow." To overcome this, he suggests a halfway point of growing large, shaped pieces that can be joined in the conventional way. The flat panels needed to make seats and table tops will also present something of a challenge although techniques for growing square bamboo posts for use in traditional Japanese houses are well established and could be adapted to British tree species.
A future where furniture growing has replaced manufacturing sounds bizarre but appealing - a non-industrial approach where intervention is minimal and the trees are left to get on with the production. Growing large quantities of furniture would need huge areas of land but Mr Cattle argues that his production method is feasible because grown furniture will last far longer than conventional pieces and growing can be scattered around the country on small-scale sites. "Relying on the sun's energy and avoiding the polluting aspects of machining, laminating and gluing is an attractive prospect. Furniture can be grown relatively near to where it's needed - DIY enthusiasts could use their own gardens."
However, on a rather more realistic note, Mr Cattle is resigned to his idea meeting considerable resistance. "Its a radical proposal that will demand quite a substantial rethink for both industry and the public; furniture will look more organic and shapes will be more flowing."
The concept of growing your own furniture is actually far from new - both the Egyptians and Greeks made chairs using this technique - but apart from agriculture implements and walking sticks with right angled handles, most controlled tree growth in recent times has been decorative.
Today, our fixation with the predictable results that industrial production lines offer has meant that skills in living design and the potential of controlled tree growth for practical uses have remained unexplored - until now.
Chris Cattle has a quiet conviction about his idea that draws you in - however crazy it sounds. "This is a move away from throw-away culture towards manufacturers becoming concerned for the life-cycle of a product," he says. "After all, a piece of grown furniture could produce the seeds for future designs."
A growth industry
1570-1305 BC Three-legged stools thought to be made from pieces of wood grown into curved shapes were commonplace in Ancient Egypt (an example is on display at the British Museum).
500 BC The legs of Greek Klismos chairs used wood that had been artificially trained in order to get correct curvature.
15-1600 Garden houses made from living trees originated in the Middle East and spread to Europe. There are accounts of a three-storey version at Cobham, Kent, which was large enough to hold 50 people.
Until 1940s grown pitchforks and walking sticks were common. The forks were traditionally produced in southern France with three or four branches pruned to make the prongs; walking sticks grown in Surrey were produced by planting saplings at an angle to the ground in order to produce right- angled handles.
1908 John Krubsack, a farmer in Wisconsin USA, grew a chair from seed using 28 box elder trees to form the legs, back and seat - it took 11 years to grow.Reuse content
