Renovating an apartment in Spain is a decision that can significantly impact both the quality of life of its inhabitants and the value of the property. It is an important decision, being both challenging and exciting at the same time. On the other hand, the cost of a renovation can vary considerably, depending on different factors, such as the type of renovation, the geographical location, the materials chosen, and the size of the space. Let's learn the key details about this topic.
A partial renovation involves making changes or improvements to specific areas of a home without the need for a complete refurbishment. This can take the form of a comprehensive renovation of one area, such as the kitchen, or the modification of part of the property, such as changing the flooring. This type of renovation covers various tasks, such as installing new flooring, refurbishing walls and ceilings by painting them, replacing taps, appliances, bathroom fixtures, or furniture in the kitchen and bathroom, as well as improving the efficiency and safety of electrical and plumbing installations. Partial renovations are ideal for those looking to modernize their home without undertaking a comprehensive project, as they are generally more economical and quicker, which means less inconvenience and an increase in the value of the property.

As the name suggests, this involves a total renovation of the apartment, which entails restructuring spaces and making significant structural changes. This process involves redistributing rooms, updating the layout, and opening or closing spaces as necessary. It also involves a complete renovation of the electrical and plumbing installations, as well as a comprehensive modification of the kitchen and bathroom spaces. The installation of new materials for floors, windows, and doors that promote energy efficiency and a contemporary design is also considered. Comprehensive renovations are particularly suitable for homes that require a total update or that aspire to a significant increase in their market value.
The cost of renovating an apartment in Spain can be influenced by multiple factors:
The larger the surface area, the higher the cost of the renovation. Size is a crucial indicator for calculating the cost. It is reasonable to assume that the more space there is, the higher the associated costs will be. The cost per square meter or square foot can vary significantly, ranging from €300 to €700 in the most affordable locations and exceeding €1,200-€1,500 in the most expensive ones. Therefore, when drawing up the budget, it is essential to consider the total area to be renovated.
Renovations in cities with a high cost of living, such as Madrid or Barcelona, tend to be more expensive compared to others. Each city has a different economic level that directly influences the final budget.
A complete renovation is generally more expensive than a partial renovation. The price also depends on which specific areas you want to renovate. Renovating a bathroom or kitchen can incur additional costs due to the need for specific, high-strength materials. Likewise, partial renovations, such as dividing a space, tend to have a higher cost per square meter compared to a more extensive renovation.
Choosing high-quality materials can increase the total budget. The quality of the materials selected has an impact on the cost of the renovation. Using durable, high-standard materials can increase the final price, while opting for more economical alternatives can lead to considerable savings. It is essential to weigh up the relationship between quality and price, taking into account the needs and expectations of each project.
The costs associated with hiring professionals in this sector can vary; hiring an architect or interior designer may involve an additional cost. It is essential to consider not only the price, but also the reputation of the renovation company you choose. Opting for a very inexpensive company could end up being more costly in the long run.
In certain cases, permits are required to carry out work, which can affect the total cost of the renovation.
This aspect encompasses the collection, transport, and disposal of discarded materials and waste generated. Through proper management, compliance with current regulations is ensured, a sustainable approach is followed, and the environment of common areas shared with neighbors is respected.
During the renovation of an apartment, the following activities can be carried out:
Initial assessment
Detailed assessment of the current condition of the property and the specific needs of the owners.
Design
Development of a plan to determine the redistributionof spaces, as well as the selection of styles and materials appropriate for the project.
Demolition
Dismantling of unwanted elements, such as internal partitions or old flooring. During this phase, structures such as non-load-bearing walls, surfaces that have been damaged or no longer fit with the new design concept are removed. This stage may also include the removal of tiles, cladding, and all types of obsolete elements.
Construction
Installation of new structures and reconfiguration of interior spaces. This may include building new partitions, creating open spaces, or modifying existing areas to maximize their usefulness.
Finishes
Painting, flooring installation, and all the decorative details that add a personal touch to the home.
Technical facilities
Execution of electrical and plumbing work, ensuring the functionality and safety of the systems. This phase includes everything related to heating, hot water, air conditioning systems, and other technological aspects that guarantee comfort in the home.

One of the most important things to consider when discussing a renovation is the size of the apartment. Small apartments tend to have a higher cost per square meter than larger apartments. This is because, in small spaces, the work of professionals and the logistics involved require more time and effort.
Below are estimates of the cost of renovating an apartment in Spain, based on square footage. Keep in mind that these prices are approximate and may vary depending on the factors mentioned above.
Depending on the quality of the materials and the location of the property, the average cost of renovating a 50-square-meter apartment ranges from €18,000 to €30,000.
Generally, the budget for a complete renovation of a 60m² house can be around €25,000 to €30,000, depending on the initial condition of the property, its location, and the quality of the materials used for the renovation.
Price for renovating a 70-square-meter apartment
We can say that the average price of a comprehensive renovation for a 70-square-meter apartment could range from €56,000 to €87,500, depending on the materials selected and the circumstances of the project.
How much does it cost to renovate a 90-square-meter apartment?
Renovating a 90-square-meter apartment can cost between €75,000 and €100,000, depending on the circumstances mentioned above.
Price for complete renovation of 100 square meters
The cost of renovating a 100-square-meter apartment can vary between €80 ,000 and €125,000, plus VAT. Partial renovations can cost between €80,000 and €90,000, while complete renovations can reach prices of up to €125,000, depending on the quality of the materials used and the city where you live.
When calculating the cost of renovating a house, one of the most influential factors is the size of the property. In the case of a 150-square-meter house, an estimated calculation would be between €98,000 and €155,000, if you opt for high-end materials and a significant redistribution of space.
It is advisable to request several quotes from different contractors to get a better idea of the costs in your specific case and ensure that it fits your needs and budget.
The first areas to be renovated in an apartment are usually the most critical ones, such as the kitchen and bathroom. These spaces require priority attention due to their frequent use and plumbing installations. It is necessary to demolish, as decided, the cladding, flooring, fixtures, toilets, doors, windows, and other items that will not be reused. It is very important to take into account the technical plans at all times to avoid collapses in the infrastructure. Likewise, debris must be collected in containers or bags for later removal.
The duration of a comprehensive renovation can range from 2 to 6 months, depending on the size of the apartment and the complexity of the work to be done. Simpler renovations can be completed in less time, while complex renovations involving significant changes to the layout and systems can take up to 6 months. Planning, choosing the right contractors, and effective management are essential to meeting the established deadlines.
The ideal time to renovate an apartment in Spain can vary depending on personal preferences and market conditions. Generally, the off-season, which covers the fall and winter months, is a favorable option, as these periods tend to be less busy for renovation companies, which can translate into more competitive prices and better completion times. It is also important to consider weather conditions, as structural renovations are best carried out in spring or summer, when conditions are more conducive to outdoor work. Finally, keeping an eye on market demand and the services on offer can be key to finding the best prices and taking advantage of opportunities to optimize your renovation investment.
