Engineeredarchitecturalsolutions.
Green walls, railings and invisible grills, safety nets, aviaries, façades and padel courts. Designed, supplied and installed across India by one team.
We build the systems that make buildings greener, safer and more open: structures for plants to climb, for people to lean on, for birds to fly beneath, for games to be played in and for buildings to wear. Designed, engineered, supplied and installed by one team, with one point of responsibility from the first drawing to handover.
