JYTAS develops and constructs large modular buildings for public and private clients. Applications include offices, schools, daycare, healthcare, laboratories, housing and specialised institutional facilities. The company manages design development, engineering and project coordination, produces modules under factory conditions and assembles them on prepared foundations before completing connections, façades and site work.

Projects can be permanent or relocatable and are customised in architecture and technical specification. The service is aimed at developers, contractors and public-sector building owners.
