In context-specific projects ten Westenend investigates the representation and perception of places and ways in which meaning is attached to them. Research processes take shape in cartographic works, choreographic and spatial interventions, reconstructions, (music) compositions, as well as short films and publications.

Projects include Perfect Day (2008), Contour (2013), Tractordans (2014), and Growing Archive of (Re)construction (2018–ongoing). The latter consists of artistic research into representations of the history of the Colonies of Benevolence in the Dutch province of Drenthe. Through this project she has been affiliated with LASP (Research Group Art & Spatial Praxis) since 2020. Ten Westenend lectures at Design Academy Eindhoven where, among other things, she developed the educational program Mapping the City, an introduction to cartography and participatory field research. She also teaches at the master in interior architecture at the Royal Academy of Art, KABK, The Hague.
