Legalisation, condominium registration and design

We guide property owners in Croatia through building legalisation and condominium registration – from the as-built survey to the as-built decision and registration in the land register. For investors, we design wind farms and roads and provide construction supervision and consulting.

Legalisation and condominium registration

Legalisation reopened on 16 May 2026.Learn more →

Legalisation

Buildings constructed by 21 June 2011 can be legalised again, with no deadline for applications. We prepare the as-built survey and handle the procedure through to the as-built decision (rješenje o izvedenom stanju).

Condominium registration

Condominium plans (elaborat etažiranja) for flats and commercial units, through to the registration of each separate unit in the land register.

From conceptual design to use permit – design, permits and supervision in one place.

Wind farms

Civil design for wind farms: access roads, crane hardstands and turbine foundations, from preliminary to detailed design. Together with long-standing partners, we provide complete design documentation and supervision across all disciplines.

Client experiences

“When we took over the Senj Wind Farm project, we were looking for a reliable partner with in-depth knowledge of the local legal and regulatory framework and the specific challenges of developing and delivering infrastructure projects in Croatia. We found such a partner in AS Inženjering, who supported us throughout all key stages of the project. Our confidence in their expertise is further reflected in the appointment of Mr Zlatko Prpić as Chief Site Engineer.”
