We’ve all grown-up building and dismantling Lego bricks. The Lego we know has turned all organic and environment-friendly. World’s first Functioning Lego Greenhouse designed by Sabastian Bergne has been unveiled at the 2011 London Design Festival. The cute little Lego house is made up of a whopping 100,000 Lego bricks. The in-growing Tomatoes, peppers, sunflowers and other flora are all encased with Lego bricks on all 7 sides, including the earth! What a brilliant design!
