According to the magazine:
The idea for Simon Pillard and Philippe Rossetti’s Lego kitchen sprouted five years ago, when Pillard put 500 blocks and a day’s worth of work into building a Lego-legged chair. The designing duo—–who create products together under the name Munchausen—–recently gave the seat a colorful companion. They covered their kitchen island—–a simple wooden block—–with 20,000 Lego pieces.
