The project S.O.U.L.: Sustainable Optimised Urban Living objective was to develop a holistic sustainable approach to housing design, and aim to be carbon neutral, citizen centric and a positive contribution to the city of Nottingham.

Drawbridge Housing represents the green link between Nottingham Castle and the City Centre. The concept was to develop a healthy and sustainable urban environment that allowed the community to interact and be connected with the natural and historic context, by adopting a dynamic, modular and staggered system for the current undeniable requirement to achieve a more thoughtful, conscious and well performing built environment that could be resilient and adaptable for the future. The design aspirations were to achieve Passive House standard and a Carbon Neutral proposal. The first was successfully achieved, and the later was achieved by heat demand neutrality and a low carbon material selection.
