According to CABE (UK Commission for Architecture and the Built Environment) research, well-designed buildings, spaces and places contribute to a wide diversity of values and benefits. The 'paved with gold' project looked at the question how the extra financial value that good street design contributes can be calculated. In total, ten high streets in London were selected as case studies. The research showed that better streets result in higher market prices and that good design is valued by the people who use these streets. These benefits were calculated by using specific tools, such as the pedestrian environment review system (PERS), regression analysis and stated preference surveys. Because an increased quality in the design of streets has beneficial effects, design should be of increasing importance to local governments, developers and businesses, researchers state.
