What is considered a partial renovation?

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. 

What is a comprehensive renovation?

As the name suggests, this involves a total renovation of the apartment, which includes restructuring spaces and making significant structural changes. The process may involve redistributing rooms, modifying the layout, or opening and closing spaces as needed. It also includes a complete renovation of electrical and plumbing installations, as well as comprehensive updates to the kitchen and bathroom areas. Additionally, it involves installing new materials for floors, windows, and doors that enhance energy efficiency and contemporary design. Full renovations are particularly suitable for homes that require a complete update or aim to significantly increase their market value.

Factors affecting the cost of a renovation

The cost of renovating an apartment in Spain can be influenced by multiple factors:

Floor size

The larger the surface area, the higher the renovation cost. Size is a key factor in calculating expenses. As the space increases, the associated costs also rise. The cost per square meter can vary significantly, ranging from €300 to €700 in more affordable areas and exceeding €1,200 to €1,500 in higher-cost cities. Therefore, when planning your budget, it is essential to consider the total area to be renovated.

Location

Renovations in cities with a higher cost of living, such as Madrid or Barcelona, tend to be more expensive than in other areas. Each city has a different economic level that directly influences the final budget.

Type of renovation

A full renovation is generally more expensive than a partial one. The price also depends on the specific areas you want to renovate. Remodeling a bathroom or kitchen, for example, may involve additional costs due to the use of specialized materials and installations. Likewise, partial renovations, such as dividing a space, often have a higher cost per square meter compared to a more extensive renovation.

Quality of materials

Choosing high-quality materials can increase the total renovation cost. The quality of the selected materials directly impacts the overall budget. Using durable, premium materials may raise the final price, while opting for more affordable alternatives can lead to considerable savings. It is essential to carefully balance quality and price according to the needs and expectations of each project.

Labor

Costs associated with hiring professionals in this sector can vary; hiring an architect or interior designer may involve additional expenses. It is essential to consider not only the price but also the reputation of the chosen renovation company. Opting for a very low-cost company may end up being more expensive in the long run.

Permits and licenses

In certain cases, obtaining permits to carry out the work is required, which may affect the total cost of the renovation.

Waste management

This aspect includes the collection, transportation, 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 shared common areas with neighbors is respected.

What is involved in renovating an apartment? 

During the renovation of an apartment, the following activities may be carried out:

Initial assessment

Detailed assessment of the current condition of the property and the specific needs of the owners.

Design

Preparation of a plan that defines the redistributionof spaces, as well as the selection of appropriate styles and materials for the project.

Demolition

Construction

Installation of new structures and reconfiguration of interior spaces. This may include building new partitions, creating open areas, or modifying existing spaces to maximize their functionality.

Finishes

Painting, flooring installation, and all decorative details that add a personal touch to the home.

Technical installations

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.

It is advisable to request several quotes from different contractors to better understand the costs in your specific case and ensure the project fits your needs and budget.

What is the first thing to renovate in an apartment?

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. 

How long does it take to fully renovate an apartment?

The duration of a full renovation can range from 2 to 6 months, depending on the size of the apartment and the complexity of the work. Simpler renovations may be completed in less time, while projects involving structural changes or system upgrades can take up to 6 months. Proper planning, selecting the right contractors, and effective project management are essential to meet established deadlines.

When is the best time to renovate?

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.
