LEGO always seems to create some of the most fascinating and innovative collaborations around. Recently, London-based designer Sebastian Bergne was commissioned by LEGO UK to construct a public installation for the 2011 London Design Week. Sebastian and builder Duncan Titmarsh spent  quite a bit of time constructing their functional greenhouse in North East London. The foundation was built entirely from LEGO bricks and looks amazing illuminated at night. LEGO's Greenhouse will be open to the public until September 25th. [DesignBoom]
