I recently completed the renovation of my apartment in Madrid’s Chamberí district, a process that took approximately 4 months. Seeing many members in the forum asking about old apartment renovations, I wanted to share my experience to help others avoid some common pitfalls.
Pre-Renovation Preparations
First and foremost, you must obtain legal permits to renovate an apartment in Madrid. My apartment was built in the 1960s and falls under protected building regulations, making the application process quite complex. When submitting the application to the City Hall’s Urban Planning Department, you’ll need: property deed, renovation plans signed by an architect, and consent letters from neighboring residents. The entire approval process took about 6 weeks, with costs around 800 euros.

Budget Planning and Quote Comparison
I consulted with 5 renovation companies, and the price differences were quite significant. The cheapest quote was 18,000 euros, while the most expensive reached 32,000 euros, all for the same 75 square meter renovation area. I ultimately chose a mid-range company, primarily valuing their experience with old building renovations. Important note: if your Madrid apartment contains asbestos materials, removal costs will add an extra 2,000-3,000 euros, as it requires specialized asbestos handling certification.
Here’s a breakdown of my main renovation projects and actual costs:
| Renovation Item | Budgeted Amount | Actual Cost | Notes |
| Plumbing and electrical replacement | 4,500 | 5,200 | Discovered severe deterioration requiring complete replacement |
| Kitchen and bathroom renovation | 8,000 | 8,800 | Including fixtures and cabinets |
| Flooring and walls | 5,000 | 4,600 | Chose cost-effective materials |
| Door and window replacement | 3,500 | 3,500 | Double-glazed soundproof windows |
| Miscellaneous expenses | 2,000 | 2,900 | Waste removal, temporary costs |
| Total | 23,000 | 25,000 | Approximately 9% over budget |
Important Considerations During Construction
The biggest issue during construction was noise complaints. Madrid regulations stipulate that construction work is only permitted from 8 AM to 8 PM on weekdays, with noise prohibited on weekends and holidays. I proactively gave small gifts to upstairs and downstairs neighbors and explained the situation, but still received one complaint. I strongly recommend strictly adhering to time restrictions, otherwise you may face fines and risk issues with your quiet Madrid apartment.
Another critical point is load-bearing walls. I originally wanted to open up the living room and kitchen, but after inspection, the architect discovered that wall was a load-bearing structure. I had to abandon this idea and instead created a wide passage with a sliding door, which turned out quite well. Structural blueprints for these old buildings are often incomplete, so it’s essential to have professionals conduct on-site assessments.
Practical Advice Summary
Several tips for those planning apartment renovations: First, budget at least 10-15% flexibility, as old apartments always present unexpected situations; second, when selecting a renovation company, always verify their insurance and qualification certificates, and consider reviewing Madrid apartment design examples; third, it’s best not to live in the apartment during renovation—the dust and noise are truly unbearable; fourth, confirm all changes and additional costs in writing to avoid disputes later.
While the entire renovation process was challenging, seeing the completely transformed home is incredibly rewarding. If you have any specific questions, feel free to leave comments below, and I’ll do my best to answer. Wishing everyone smooth renovation projects!
