During the years 2018–2020, Nåttarö Gård & Resort AB participated in the Sustainable Gateways project, which was part-financed by the European Union's Interreg Central Baltic programme. Within the framework of the project, the guest port's service house was built and two floating jetties created more guest places in the port. The port's operations and services were developed in collaboration with the Brahea Center at the University of Turku.
