How long an apartment renovation takes in Sofia
In Sofia, how long an apartment renovation takes depends not only on the floor area but on how well the coordination between stages has been planned. In a dense urban setting, delays most often come from organisational dependencies rather than from any single task.

In prefab panel blocks and older buildings, it is important to start clearly with a technical site visit, because hidden defects and access restrictions have a direct effect on the schedule. Without a proper assessment, the timeline remains provisional and hard to manage.
The model that works best is a staged plan by room and priority, with interim checks and a clear order between preparatory, plumbing and electrical, and finishing work. For larger projects, a good starting point is an 80 m² apartment renovation, where the phases are clearly structured around the city's logistics.
What matters most
- The condition of the plumbing and wiring, and the need for additional preparation.
- The number of interdependent tasks within the project.
- Restrictions on access, transport and the building's common areas.
- Any changes to the scope after the strip-out and the technical assessment.
- Room-by-room staging and coordination between separate crews.
- Materials logistics and the organisation of waste removal.
Typical situations in Sofia
- An apartment in a prefab panel block that needs its plumbing and wiring completely renewed.
- A property in a central area with limited time windows for work and difficult access.
- A home with a mixed scope: partial renovation in some rooms and a full renovation in others.
- A renovation in an occupied home, where the schedule is agreed around everyday use.
Mistakes to avoid
- Fixing a deadline before the scope has been properly defined in technical terms.
- Overlapping stages before the critical dependencies have been resolved.
- Underestimating the time needed for preparation and logistics in an urban setting.
- No interim checkpoints in the schedule.
Practical advice
- Ask for a schedule with phases and specific criteria for moving on to the next stage.
- Plan a buffer for corrections where the property's starting condition is old.
- Agree access and logistics in advance to avoid unplanned pauses.
- Work to a written framework in which every change to the scope is recorded in good time.
