"It is kind of like making a big jigsaw puzzle," Parvin told AFP. "It is basically magic as far as I'm concerned."
Parvin told of graduating university in 2008 only to encounter a bleak job market for architects. He veered from the traditional career path, and took part in launching WikiHouse about 18 months ago.
A growing "makers movement" coupled with increasingly affordable technology such as 3D printers and CNC machines is letting consumers become creators of goods they desire, according to Parvin.
"How awesome would it be if we had a kind of Wikipedia for stuff?" he asked rhetorically. "How much would that change the rules? I think technology is on our side."
He sees the great design project of this century as the "democratization of production."
WikiHouse is putting itself to the test in the favelas, or shanty towns, of Brazil, hoping that a CNC machine made available for creating furniture will eventually be put to use building homes with the potential to transform slums.
"Slums are being built anyway," Parvin said. "If people are going to build things for themselves, wouldn't it be cool if what they make is not rubbish?"
