This section presents the sustainable business model innovation developed for the municipal restaurant planned to be opened in Cumalıkızık Village, which is included in the UNESCO World Heritage List. Within the scope of the REMODEL Horizon Europe Project, a multi-stage process was carried out using Gassmann's Magic Triangle model and the Business Model Canvas framework. Supported by competitor analysis, field observations, and stakeholder interviews, this process structured the value proposition and business model with concrete strategies. The model aims to integrate the preservation of cultural heritage, support for local development, and digitalisation with sustainability. The study provides both a theoretical and practical roadmap for stakeholders seeking to develop innovative business models in tourism.
