The planting of vernacular tree species will ensure that the Depot’s roof will remain a large urban park, open for all, with a very reduced maintenance cost. A large section of the vegetated roof will be reserved for urban agriculture, using the organic refuse for composting and as a fertiliser to the growth of local vegetables.
The site has a gradient of environmental quality which decreases from East to West and from North to South. The residential and civic areas of the complex have been located on the Northeast area of the site, to avoid casting shadows on the park, diminishing exposure to noise and pollution from the Seouloegwaksunhwan Expressway and enjoy the proximity to the Jangji-Dong Creek Park, which will act as a landscape feature and environmental regulator. Beyond the environmental pollution we have located the residential buildings in a place where they can be insulated from the vibration from buses, occupying a minimum footprint.
