A French firm has pioneered a residence-building program of machined wood “bricks” that you faucet into put with a mallet.
Right after a ten-yr wrestle to get off the ground, it has now offered far more than a hundred units, and has accredited the engineering in Hungary and the Netherlands.
The corporation, Brikawood, expenses its technique as “the picket brick that can be installed without nails, screws or glue”.
It states the air- and water-tight structure of a substantial, 120-sq-m dwelling can be erected in 15 times.

“Exceptional” mechanical rigidity
The “bricks” are actually structural cells fashioned by panels of sustainably developed Douglas Fir that interlock with self-tightening dovetail and rabbet joints.
Brikawood states the partitions have “exceptional” mechanical rigidity and structural steadiness.
The wall cavities fashioned by the cells are crammed with wood chips created throughout machining, for insulation.
This and the airtightness of a Brikawood dwelling qualifies it to meet up with the Passive Home common for vitality performance, that means very very little heating or cooling is needed.

Dealt with only with linseed oil, the Brikawood structure is designed to face up to the factors on its personal, devoid of external facades, plastering or other coatings.
The timber parts are machined according to an architect’s 3D drawing, and are delivered to website in pallets, with instructions.
Roof trusses and other joinery assemblies are also furnished.
Exactly where a residence is below 50 sq m in space, the home’s homeowners can assemble it on their own with essential equipment and no construction encounter.
Higher than 50 sq m, a Brikawood-trained crew puts it together.
Kits range in measurement from 20 sq m, about the dimension of a significant yard studio, to 300 sq m, the dimensions of a massive, multi-bed room dwelling. They can be multi-storey.
The for every-sq-m development expense of a Brikawood property is relatively minimal, at about €1,300, the firm says.

Business president Patricia Dutreux informed GCR that a latest kit for a 100-sq-m house was priced at €180,000, with every thing provided.
Most likely wouldn’t do it all over again
Dependent in Laroque D’Olmes, near the Pyrenees in southern France, Dutreux reported it took 10 challenging decades for Brikawood to get to this point.
A business attorney, she claimed she and the system’s designer, the engineer Alain Romero, encountered resistance at each and every stage, from functionality evaluations, to insurers, and to developing handle authorities.
“We had been confronted with lobbyists who did not spare us,” Dutreux explained in an e mail. “We experienced to deal with some not incredibly pleasant situations.”
She extra: “We labored on your own with no money guidance, we experienced to market all the things we owned and we experienced to borrow huge amounts of income.
“We are happy of what we managed to put in place. If we had to do it once again currently, we would give up.”
She characterised France as “not a nation exactly where ecological innovation is accepted and supported”.
“It’s not uncomplicated to dare to modify practices at a time when concrete is so essential,” she suggests.
“We had to combat at just about every stage”
They confronted operational disasters as very well.

To begin with they outsourced the machining operations to a modest subcontractor with a handful of staff members who turned out to be unqualified.
Inside of two several years the procedure was struggling with fiscal ruin.
That led them to choose greater companies, utilizing around 400 individuals in total, and the procedure commenced to operate smoothly.
By 2015, Brikawood experienced secured its intellectual property by buying all 11 of the system’s applicable patents.
“If assignments are multiplying these days, it is because we dared to acquire the plunge,” suggests Dutreaux. “We experienced to combat at each stage.”
Transmitting the strategy
To day, 124 dwelling kits have been acquired and assembled, with ground places ranging from 20 sq m to 180 sq m.
Dutreux states a dozen multi-storey property kits have bought considering the fact that 2018.
The business is now offering licences to transmit the Brikawood notion internationally.
Not long ago, licenses have been offered for the distinctive manufacture and internet marketing of Brikawood households in Hungary and the Netherlands.
