When planning a full apartment renovation in Barcelona, cost is usually the first concern — and also the one with the most uncertainty. Unlike new construction, renovations often involve existing conditions that are not fully visible until work begins, which is why prices can vary significantly from one project to another.
This article explains how renovation costs are typically structured, what influences the final budget, and how to approach cost planning realistically.
Typical renovation cost ranges in Barcelona
As a general reference, a full apartment renovation in Barcelona usually falls within these ranges:
- 900 € – 1,400 € per m² for standard renovations
- 1,500 € – 2,000 € per m² for higher-quality finishes or technically complex projects
These ranges usually include demolition, construction works, new installations (electrical, plumbing, HVAC where applicable), finishes, and basic project coordination. They do not always include furniture, appliances, or custom carpentry unless specified.
What actually affects the final cost
Age and condition of the building
Many apartments in Barcelona are located in older buildings, often with outdated installations or hidden issues. Electrical systems, plumbing, and floor structures may require partial or full replacement, increasing costs beyond initial estimates.
Structural interventions
Removing walls, reinforcing slabs, or modifying load-bearing elements requires technical studies and permits. These works add complexity, time, and cost but are sometimes unavoidable to achieve the desired layout.
Quality of finishes
Flooring, bathrooms, kitchens, doors, and windows represent a large portion of the budget. Small choices repeated across an entire apartment can have a significant impact on total cost.
Permits and technical documentation
Depending on the scope, renovation projects may require municipal permits, architectural or engineering documentation, and inspections. These are necessary steps and should be budgeted from the beginning.
Why prices often change during renovations
Cost overruns usually don’t come from poor execution, but from changes introduced after work has started. Late design decisions, upgraded materials, or newly discovered conditions can all affect the final budget.
This is why defining scope and specifications early is essential.
Practical budgeting advice
- Request detailed, itemised quotes
- Clarify what is included and what is not
- Set aside a 10–15% contingency for unforeseen issues
- Avoid making major changes once construction is underway
Conclusion
A full apartment renovation in Barcelona is a significant investment. Realistic budgeting, clear scope definition, and experienced coordination are the best tools to keep costs under control and avoid unnecessary surprises.
