From the largest living wall in North America to high rises wrapped in vertical gardens, we have seen quite a few impressive green walls. But LTL Architects has built an 84-foot-long green wall in a New York City office that might just be our favorite. Located in the offices of OpenPlans, LTL’s masterpiece is a near-exact replica of Central Park, complete with ponds, lawns, and specific paths. The green wall is surrounded by built-in shelves which mimic the streets and avenues of Manhattan.
