I’ve been in Spain for a few years now, and last year I finally took the plunge and bought a rather old chalet in the suburbs. While I loved the structure and the garden, the interior decor was incredibly dated—think dark wooden doors and gaudy tiles… So, from the day I got the keys, my long renovation journey began. I’m starting this post to share the pitfalls I encountered and some lessons learned, hoping it can be a reference for others planning a similar project.
Preparation Phase: Permits Are the Top Priority
In Spain, any modification that alters the structure of a house requires a building permit. You must not skip this! I was tempted to do it secretly at first, but a neighbor warned me that if you get reported, you not only face hefty fines but might also be ordered to restore the property to its original state, which isn’t worth the risk. There are mainly two types of permits:
- Obra Menor: This usually covers interior renovations that don’t affect load-bearing walls, the building’s exterior, or structural integrity, such as replacing floors, painting walls, or changing kitchen and bathroom tiles. The application is relatively simple and approval is quick.
- Obra Mayor: If your renovation plan involves removing or altering walls, adding rooms, changing exterior doors and windows, or building an extension, you must apply for this. It requires detailed plans and drawings from a licensed architect. The approval process can be very long, taking anywhere from a few months to a year, as detailed in this post on renovating a wooden cabin. So, you absolutely must plan ahead!
Choosing a Construction Team and Controlling the Budget
Finding a reliable construction team is crucial! My advice is to ask around, see their work, and compare multiple options. It’s best to get recommendations from friends or check reviews on local forums. Before signing a contract, insist on a detailed quote that clearly lists the brand, specifications, unit price for each material, and labor costs for every item. Here’s a simple budget comparison table I created; you can use this as a model when requesting quotes:
| Project | Material Brand/Specs | Unit Price | Total Price |
| Full House Painting | Valentine - Plástico Mate | 12€/m² | 2,400€ |
| Living Room Flooring | Tarima AC5, 8mm | 25€/m² | 1,250€ |
| Kitchen Tiles | Porcelanosa 60×60 | 40€/m² | 1,600€ |
| Labor Cost | - | - | 8,000€ |
Note: This table is just an example; actual prices vary greatly by region and materials. Be wary of “lump-sum” quotes that only give you a total price, as they will almost certainly add extra costs later on. Also, it’s best to pay in installments: a portion at the start of the project, another after a mid-project inspection, and the final payment upon completion.

Some Personal Thoughts on Interior Remodeling
Let’s talk about the specific changes. The main issues with my house were lighting and spatial layout. The original living room and dining room were separated by a non-load-bearing wall, making the space feel cramped. After confirming with an architect, I decided to knock down the wall, creating an open-plan living, dining, and kitchen area. The effect was immediate—the entire ground floor felt bright and airy! For the kitchen, I chose white cabinets with a wood-colored countertop, which is easy to clean and visually refreshing. Another tip is about the windows. If your budget allows, replacing old single-pane wooden windows with double or triple-glazed Climalit windows for better insulation and soundproofing will dramatically improve your living comfort. It’s also more energy-efficient in the long run. Although the upfront cost is high, it’s absolutely worth it.
Finally, I want to say that renovating a chalet is a time-consuming and labor-intensive process. You’ll definitely encounter unexpected problems—my water pipes burst once… it was a complete nightmare. So, maintaining a positive attitude is key! Keep good communication with your construction team and designer, and visit the site often. Though the process is tough, watching your house gradually transform into the home you’ve always wanted brings an unparalleled sense of accomplishment. I hope everyone’s renovation journey goes smoothly! Feel free to ask questions or share your experiences in the comments below!
