  • What to Consider When Renovating an Old House in 2026

    Comprehensive reform

    Renovating an old house is one of the most complex projects you can take on. Not because it’s impossible, but because behind that charming façade there are often decades of outdated services, structures that need checking and surprises that no property listing ever mentions. If you are considering buying an apartment to renovate in Barcelona, […]

Frequently Asked Questions
about OAK Construction

At OAK, we’d like to get to know you. Tell us about your needs, concerns, tastes, and lifestyle so we can provide the best solutions tailored to you and create a comfortable space that reflects your personality. We propose a visit to your home so you can explain the type of renovation you’d like, and we can assess the space’s possibilities and take measurements. Within the agreed timeframe, we’ll contact you again to present aesthetic proposals and an estimated cost based on your requests. This will be a great opportunity for you to see our work process and everything we can offer.

It all depends on the type of renovation; it’s impossible to generalize because it all depends on the complexity of each project. However, to give you some guidelines, a bathroom renovation in Barcelona will take about two weeks, a kitchen renovation about four weeks, and a complete apartment renovation in Barcelona starting at three months. These are approximate construction timelines. In addition, you have to factor in the time it takes to develop the project, which will depend on the decision-making capacity of both the client and the designer. It’s recommended to invest a significant amount of time in the interior design phase so that all the details are considered, ensuring the work runs smoothly and without downtime.

Today, it’s very difficult to estimate the price of a renovation without more information due to the wide range of finishes, qualities, and execution methods available on the market. At OAK, we propose a personalized study to address each client’s specific needs and arrive at the desired price. We work closely with the client and the construction company/designer to find the right balance between aesthetics, function, and price. Ultimately, we believe that quality should take precedence over other factors such as experience, professionalism, trust, and a good rapport.

It all depends on whether the municipality allows it or not. There are many coastal towns where it’s not permitted. Complete renovations in Barcelona during the month of August are allowed. In any case, we recommend that renovations be planned following these requirements: that the neighbors agree (this will always help maintain better harmony during the process), that the project is well-defined, with the necessary materials already ordered (many manufacturers take advantage of this time to complete their entire production run), and that it be considered as extra work time, not included in the time agreed upon with the construction company.

Depending on the town where we want to carry out the renovation and the type of work, we will have to process one permit or another. It is recommended to call the relevant Town Hall or consult the procedures section on the website of the relevant entity in order to make the inquiry. There they will tell us the type of permit, the documentation to be submitted, the general fees, waste fees, the technicians with the necessary qualifications for both the drafting of the project and the safety coordination…

At OAK, we work to make the renovation process as simple as possible for our clients, facilitating every task involved. We recommend the most suitable professionals for obtaining building permits.

OAK is a team of nearly 50 employees, in addition to a large number of regular collaborators and manufacturers. The team consists of on-site personnel, including site managers, laborers, bricklayers, electricians, drywall installers, plasterers, painters, and fitters; and office staff made up of technical architects, interior designers, administration, purchasing, and HR personnel.

On the other hand, we talk about regular collaborators and manufacturers, because we surround ourselves with the best professionals who can guarantee the desired quality of finishes.
