The Netherlands is facing a structural housing shortage, which in 2024 has risen to approximately 410,000 dwellings. To address this issue, the government has set the ambitious goal of realizing one million new homes by 2030. However, the feasibility of this target is under pressure due to the lengthy lead times associated with real estate development. Research indicates that the average project takes approximately 120 months from initiation to completion, of which only 30 months are allocated to actual construction. This thesis focuses on reducing the lead time of so-called greenfield real estate projects, developments situated on undeveloped land at outskirts. The research scope spans the period from project initiation to the commencement of construction. Through a combination of literature review, four case studies, and expert interviews, this study identifies the development phases that are most time-consuming, the factors that contribute to these delays, and potential strategies for improving process efficiency. The study yields both theoretical and practice-based insights that are relevant to policymakers, project developers, and other stakeholders involved in housing development. Accelerating the development process is shown to be essential for achieving national housing goals and effectively addressing the housing shortage in the Netherlands.
