How Historic Building Restoration Works in Turkey: Survey, Restitution and Conservation Council Approval
- Major works on a listed building in Turkey require measured survey, restitution and restoration projects approved by the Regional Conservation Council for Cultural Assets.
- The measured survey documents the building as it is today; restitution reconstructs its original state from historical documents and physical traces.
- No works may start on a listed building without council approval, and supervision continues during implementation.
- ÇET Yapı brought Topkapı Safa Hamam back into use in about 5 months in 2010, together with Topkapı Doğa College on the same block.
Repairing a historic building is a different discipline from new construction: the aim is not just to make it sound, but to bring it back to life while preserving its original values. Based on ÇET Yapı's Topkapı Safa Hamam project, carried out under its renovation and restoration services, here is how restoring a listed building in Turkey works.
Key terms
| Term | What it does |
|---|---|
| Measured survey (rölöve) | Measures the building as it stands and documents it in plans, sections, elevations and details. |
| Restitution | Reconstructs the original or earlier state from surviving traces and historical documents. |
| Restoration project | Defines how the building will be repaired, which materials and techniques will be used, and its new function. |
| Renovation | Mostly for unlisted buildings: updating a building to today's needs. |
Step-by-step restoration process
- Check listing status: confirm whether the building is listed and its conservation group.
- Documentation and survey: measurements, photographic documentation, material and damage assessments.
- Restitution research: archives, old photographs and physical traces are studied.
- Restoration project: intervention decisions, materials and the new use are defined; a structural strengthening project is prepared if needed.
- Regional Conservation Council approval: the survey, restitution and restoration projects are submitted to the relevant council.
- Implementation: works follow the approved project with specialist teams and compatible materials; unexpected findings are shared with the council.
The Topkapı Safa Hamam example
ÇET Yapı handled the Safa Hamam in Topkapı together with the Topkapı Doğa College project on the same block (2113/422). Completed in about 5 months between 17 May and 12 November 2010, the works brought the bath building — 200 m² footprint and 510 m² total construction area — back into use as part of the education campus, showing how a historic building can live on with a new function.
Most common mistakes in restoration
- Starting before council approval: unauthorised works on a listed building have serious legal consequences.
- Incompatible materials: hard cement-based mortars can damage original masonry.
- Skipping documentation: recording before and during works is also a record for future generations.
- Forcing a function onto the building: the new use must fit the loads and spatial layout the building can bear.

Frequently Asked Questions
What is the difference between survey, restitution and restoration?
A measured survey (rölöve) documents the building's current state in drawings. Restitution reconstructs its original or earlier state based on surviving traces and historical documents. The restoration project defines how the building will be repaired and used.
Who approves restoration of a listed building in Turkey?
Projects for major repair and restoration are submitted to the Regional Conservation Council for Cultural Assets. After approval, the necessary permits are obtained from the relevant authority before works begin.
Can a historic building be given a new use?
Yes, new uses that do not harm the building's original values and are approved by the council are possible. Topkapı Safa Hamam was brought back into use as part of an education campus.
How long does a restoration take?
It depends on size, condition, council procedures and surprises discovered on site. Design and approval often take longer than the works themselves.
