Landscape Design Landscape architects OvP Associates’ approach was to focus on four main landscape aspects: • To connect the building and the boardwalk system to a larger pedestrian network; to aid and display the sustainable systems to increase resource efficiency; to create healthy and comfortable work and people environments; and to anchor the building within the regional context. • A system of pathways links Carl Cronje Road with the building and the quarry boardwalk, thereby connecting the public spaces through a continuous accessible path network. The landscaping facilitates the sustainable processes of water recycling and natural ventilation of the basement. • The water feature system of fountains and the leivoor channel cools and transports recycled water back to the quarry and recreates the Elsieskraal River that historically flowed across the site. The flow of water directly corresponds to the process of The Edge regulating building temperature and becomes a visual element which the passer-by can experience and enjoy. • The material used in the landscaping complements that of the building in colour and form. The rock used for the garden walls is similar to that mined in the old quarry and together with the indigenous planting, anchors the landscaping in the regional context. Existing trees on the site were retained where possible and along with newly planted trees, provide windbreaks and contribute to the creation of comfortable outdoor environments for pedestrians and a healthy work environment for those occupying the building. The indigenous vegetation reduces irrigation water demand by 90%. Sustainability The Edge is designed and built to reduce energy usage and is aiming for a 5-Star Green Building of South Africa ‘design’ and ‘as built’ rating. 53
