Cooperation over the years

The cooperation with the Association for Rural Culture and Education started in 2014 with Päivi Raivio's A Sense of place project in the garden of the Seppä's House and has continued with various art projects related to the environment and water, as well as with the ITE Artists of the Year.

The partnership with Rauman Seudun Katulähetys (street mission) started with the fence for the Seppä's House in the early 2010s. The collaboration has continued through the art projects of Tasha Doremus (2013–2014), Suzanne Morlock, Glenn Messersmith and Tarmo Thorstöm (2015) and Lena Gätjens (2016), and the painting of the facade of the Seppä's House in 2017, up to the present day. RSKL is, among other things, partly responsible for the cleaning of the Art House RaumArs.

The collaboration with Rauma Region Job Seekers started in 2016 with an art project by Kelly Briggs and Nicole Hudson in 2016.

Cooperation with the Läntinen tanssin alueskus (Regional Dance Centre of Western Finland), which is based in Turku, started in 2018, after which a dance artist selected through an anonymous open call has received a place in the RaumArs residency and a regional centre's salary once a year.
