Real estate development faces numerous challenges due to the dynamic market, socio-economic developments, but also deep-rooted mentalities and practices in the sector. Real estate developers need to innovate at both a strategic and business level to overcome these challenges and remain marketable in the long term. This study explores this gap and offers a solution by answering the question: " How can the strategic and project levels of a developer be aligned to achieve a sustainable real estate development concept?". Using a design science research methodology that combines interviews, workshops and expert panels, the Sustainable Real Estate Development Canvas (SREDC) was developed and tested. The canvas harmonises the strategic view of the developer and the interests of the various stakeholders at project level to achieve a new and sustainable development concept. During the workshop, in which all stakeholders participated, a jointly developed development concept emerged as a result of the harmonisation of interests, which demonstrates the practicability and feasibility of the proposed canvas.
