The built environment is constantly exposed to societal, political, and economic changes. The COVID-19 pandemic was of major influence on the usage of office buildings. Since hybrid working became the norm, governmental offices struggled with low occupancy rates after the pandemic. This study is based on the underexposed side of sustainability, namely efficient usage of square metres through potentially sharing real estate and focuses on the public real estate portfolio and strategical management of the Rijksvastgoedbedrijf (RVB), specifically their office buildings. The RVB has two strategic goals for its portfolio, firstly to enlarge the public value of the governmental real estate and secondly to improve the services in a safe, sustainable, and innovative way. Hypothetically, value can be added to the urban context by including other functions through mixed-use development or sharing office buildings with other organisations. The main research question is: To what extent can the Rijksvastgoedbedrijf share governmental office buildings within the city of The Hague, focussing on (semi-)public organisations and mixed-use development, to optimise the utilisation of available real estate? This study consists of a literature review that provides a framework of definitions and processes. The second part is empirical research based on the DAS model and consists of interviews and document analysis. The DAS model aims to determine the approach to achieve the desired real estate portfolio by analysing the current and future supply and demand. This study has found that sharing real estate with other public organisations and mixed-use development could contribute to utilising available office space more efficiently in The Hague. However, when considering sharing governmental real estate with other public organisations, several barriers emerged. Safety concerns and unresolved financing issues are the two major barriers for sharing real estate. To be able to translate the barriers and possibilities to actual real estate adjustments, further research should be done for the portfolio.
