OCA Modular is a Santa Catarina studio focused on modular cabins for ecotourism, short-stay rentals and landscape-sensitive accommodation. Its site links the brand to Estúdio Murilo Zadulski Interiores and lists cabin sizes, contact emails and phone numbers for project discussions.

The offer appears most useful for hospitality buyers or landowners developing Airbnb-style units rather than mass housing. Buyers should request technical drawings, dry-construction scope, transport assumptions, site works and payback assumptions before committing.
