The Katoenveem is a former cotton warehouse situated in the Northern harbour area of Rotterdam. It was built in 1920, has been out of use as a cotton warehouse since 1964 and has been vacant since 2016. Over the past 100 years, the building has maintained a lot of its original character. This graduation project focusses on the question how the Katoenveem can be reused to accommodate a new function and at the same time keep its identity? Through a thorough analysis of the building and its context, this resulted in a transformation of the building into a working and living incubator which maintained its original identity, responds to the development and connects to its area.
