The Ministry of Infrastructure and the Environment, the City of Rotterdam and the Creative Industries Fund NL are IABR's main partners.

The IABR is a lead partner of the Netherlands Ministry of Infrastructure and the Environment in implementing the Action Agenda for Spatial Design (ARO) 2017 - 2020.
The IABR is funded in the Culture Plan 2017 - 2020 Budget of the City of Rotterdam and subsidized as part of the Grant Scheme for Multi-Year Architecture, Design and E-Culture Programs of the Creative Industries Fund NL (SCI).

The IABR has entered into a long-term collaboration with the Belgian organization Architecture Workroom Brussels. We will be active in each other’s domains and benefit from each other's expertise. The focus is on taking research by design to the next level and on showing and more specifically helping to implement its results in the Netherlands and Belgium.

As part of its multiyear policy plan 2017-2020, Towards a Resilient City, the IABR has entered into action-oriented collaboration agreements with the Special Envoy for International Water Affairs (Ministry of Infrastructure and the Environment) and with Resilient Rotterdam (Department of Urban Development, City of Rotterdam): the IABR–Atelier Rotterdam 2017 - 2020.

Key (research) partners involved in the realization of the IABR–2018+2020 are the Netherlands Environmental Assessment Agency, the Atelier of the Dutch Government Architect, the Team of the Flemish Government Architect, AIR and the Veldacademie.
