Milroy Perera Associates, in collaboration with Mäga Engineering, has unveiled plans for the world's tallest residential vertical garden in Rajagiriya, Sri Lanka. The Clearpoint tower will house 164 apartments spread across 46 floors within 10 kkilometers from the centre of Columbo. Overlooking the tributaries of the Diyawanna Lake in Kotte, planted viewing terraces will encircle the entire structure fed by "inbuilt self-sustaining watering systems."
