O2 is a multidisciplinary practice consisting of landscape architects, planners, urban designers, and environmental scientists. 

Founded in 1991, we specialize in analyzing development challenges in an integrated manner and creating sustainable planning and design solutions. Our work involves the intersection of natural habitats and processes with human endeavours. At broad regional scales, land use plans reflect wise stewardship of the land, while at finer scales, natural and cultural forms provide artistic inspiration for contemporary urban design.
