Greenoak Housing Association


Greenoak is a small developing housing association working in Surrey and Sussex. Since 2000 we have addressed the linked themes of sustainability, design quality and construction performance through a quality-driven development process. Our central tenet is ˜liveability": simple, passive solutions that will minimise the risk of problems for tenants and achieve good building performance. Future-proofing is achieved by allowing for renewable energy systems to be retro-fitted. The latest scheme in West Sussex is designed to CSH level 4 and is the first scheme to use renewable energy: a solar hot water system.
