The aim of this thesis was to conduct a design research and as an outcome of that research a business model prototype. The prototype was handed over to the commissioners together with a value proposition, personas, service blueprint and SWOT-analysis. Technology has made it possible to have different types of self-service businesses and this self-service garage project needs to be an easily accessible, safe space to work on vehicles in, for both minor repair or car wash. An important element of the thesis was design thinking, to find out what brings value to users and what the service should include in order for the customers to want it. Potential customers were interviewed and asked to fill out a questionnaire. A workshop was facilitated with one customer segment. The results of all three methods were then summarized into the service design tools. The focus was always on the potential customers and what they would need. In conclusion, the methods used proved to be successful. Both the researcher and the commissioners agree that the gained results are not mind-blowing news but even so, we are now aware what the customer expect and what they want. The weather in Finland supports the need for indoor spaces for consumers to work on their vehicles. Environmental aspects are important, and the customers can rely on the fact that all rules and regulations regarding the environment are strictly followed.
