What is the value of built heritage conservation? Assessing spillover effects of conserving historic sites in Singapore

Abstract

Quantifying the economic benefits of built heritage facilitates the formulation and assessment of conservation policies and programs. There is however a lack of empirical research about the economic value of built heritage in Asian cities. This lack is problematic, given the rapid pace of demolition and redevelopment of historic landscapes in Asian cities. This study seeks to reduce the current gap in built heritage research by examining whether real estate premiums are generated by the designation of buildings as ‘conserved’ in Singapore, a city-state in South East Asia. Using 20 years of housing transaction data, and controlling for building, neighborhood and year fixed effects, we found that conservation designation had a positive impact on average sale prices per square meter of built area that was largest at residential locations between 800 m to 1.6 km from the conserved site. Findings also suggest that lower-cost public housing resale units gained a substantially smaller premium compared to private housing units. While our findings suggest an economic justification for building conservation programs in Asian cities, they also raise questions about such programs potential impact on neighborhood gentrification, and the need for appropriate taxation policies to ensure horizontal equity between property owners.
