The redevelopment of brownfield sites such as port, industrial or business locations are designated for redevelopment, mostly for residential or commercial use. However, waterfront redevelopment sites are amongst the most complex to develop (Daamen, 2007). That is why it is important to understand why we choose for redevelopment to new or other uses. This research examines the intrinsic land value creation for two cases in the port of Rotterdam and how the intrinsic land value was created as a result of the actor arena and the involvement and perspectives therein. Through literature is first sought how we can explain intrinsic land value and what it comprises. Thereafter, two cases: the M4H and RDM sites in Rotterdam, are examined. These two related cases are particularly interesting as they resulted in a different outcome than a complete transformation from port to city, implying that different value creation and actor arena dynamics. It appeared that intrinsic land value can either be affected by context changes or actively be created through development. The intrinsic value of a location or land can be described through location factors. These can be categorized in factors from a classical, behavioral, institutional or evolutional approach. The different actor arena in the two cases has led to different area developments. For the RDM case, the Port of Rotterdam dominant involvement has resulted in a innovative and manufacturing cluster focused on maritime use and collaboration with educational partners. The M4H case, with the municipality as equal partner and the involvement of developers, includes a lot of residential and commercial uses too. The innovative making cluster in the M4H emerged from a mutual innovation agenda (digitalization and energy transition) and the need to enhance and diversify the economy for the port and city. It can be concluded that intrinsic land value is created through the interplay of involvement, power, actor perspectives and the C-strategies employed to impact those in one's favor. This thesis identified 10C's. This deserves more research in the future, to understand how we come to our redevelopment outcomes in the port-city interface, as well as other inner-city redevelopment projects.
