    Why renovate your flat or apartment in Barcelona?

    Renovating a flat or apartment in Barcelona is an investment with multiple strategic benefits. It enhances quality of life, maximises functionality, and leads to undeniable financial revaluation.

    Increasing the property’s value

    Planning a renovation is equivalent to increasing a property’s valuation. Updating bathrooms and kitchens is usually the first priority, as they are the most profitable and can raise the sale price by between 5% and 10%. In addition, investing in energy efficiency is essential, since it improves a decisive factor on the market: the property’s Energy Rating.

    Improving functionality and comfort

    If the goal is to provide day-to-day wellbeing, it is important to optimise the layout of the living space. Consider removing corridors to maximise usable square metres and create open-plan areas (open concept).

    Tailoring the home to your needs and style

    One of the advantages of renovating flats and apartments is the opportunity for complete customisation. You can choose bespoke furniture, sliding or glass doors and a variety of materials, as well as incorporating a flexible home office if needed.

    Anything that imagination, space and budget allow can be brought to life, especially when the aim is to achieve a comfortable home that reflects your personality and lifestyle.

    Types of renovations in flats and apartments

    Carrying out a renovation project involves different types of work, ranging from a full or integral refurbishment to various, more specific partial updates designed to achieve quick revaluation.

    The choice itself should be based on either obtaining an immediate Return on Investment or ensuring safety in obsolete installations.

    Integral renovation vs partial renovation

    Partial: This usually focuses on the bathroom and kitchen to achieve a quick ROI. Costs are lower, averaging between 300 and 600 euros per square metre, and it is ideal for a strategic update before renting or selling.

    Integral: This requires the complete renewal of outdated installations and a redistribution of the space. The duration is typically between three and six months, and costs are higher, varying greatly depending on the scale of the work, though they are estimated at over 1,000 euros per square metre in most cases. This is justified by the excellent increase in the property’s value, which can exceed 30%.

    Kitchen renovation

    The priority is an open-plan design and efficient use of space. Quartz or porcelain worktops are ideal for hygiene, and it is also advisable to choose A-rated appliances.

    In addition, fitted furniture should create areas with clean, functional lines while maximising vertical storage as much as possible.

    Bathroom renovation

    Modernise the space by replacing the bathtub with an extra-flat shower tray. You can also opt for large-format, light-coloured tiles and wall-hung sanitaryware. These elements are essential to make cleaning easier and enhance the sense of spaciousness.

    Flooring and wall upgrades

    You can smooth the walls and paint them in neutral tones, and use laminate flooring or microcement to unify spaces and create visual continuity. If you are looking for excellent thermal and acoustic insulation, install windows with Thermal Break (RPT).

    Optimising small spaces

    The key is to create the illusion of greater space. To achieve this, rely on custom-made vertical storage that reaches the ceiling and on multifunctional furniture. Combined with suitable lighting and strategically placed mirrors, this will add visual depth to any room.

    How to plan a successful renovation?

    Successful renovation of flats and apartments in Barcelona is only possible through detailed planning. This is the foundation for ensuring high-quality project execution, securing an optimal Return on Investment and maintaining full control over expenditure.

    The strategy to be implemented is based on complying with local regulations, managing costs effectively and defining the level of quality you want to achieve in the refurbished property.

    1

    Defining budget and priorities

    To define the budget, it is necessary to estimate the cost of renovating the flat or apartment. The simplest way is to break down the cost of materials, labour and indirect costs related to the project, such as technical and management fees, taxes, municipal charges, building permits and a contingency reserve.

    Any realistic budget that aims to avoid work stoppages should include a contingency fund of between 10% and 20% of the total cost of the renovation to cover unforeseen events. In addition, focus on prioritising safety by renewing obsolete electrical and plumbing installations, and then on maximising Return on Investment.

    2

    Selecting materials and finishes

    To ensure durability, select high-quality materials. For example, for insulation, invest in windows with a Thermal Break (RPT).

    For finishes, choose neutral tones and large-format porcelain or microcement flooring, which will help you make the most of natural and artificial light.

    3

    Hiring trusted professionals in Barcelona

    Avoid being swayed solely by low prices and think long term. Hiring reliable professionals in Barcelona is essential. Request at least three detailed and itemised quotations from leading experts in your area.

    Also check that they have valid liability insurance and formalise the scope of the project through a contract with appropriate guarantees.

    4

    Permits and local regulations

    Obtaining work permits for flat and apartment renovations in Barcelona is mandatory and must be done through Barcelona City Council. The type of permit required depends on the scope of the work:

     

    • Assabentat or prior notification: Required for simple finishes, such as changing flooring, tiling that does not affect the layout or painting. This is a free, informative procedure that can be completed online without the need for a technical specialist.
    • Minor Works Permit: Required when changing installations or the layout, such as major bathroom and kitchen renovations or moving non-structural partition walls. It requires the involvement of a qualified technician and payment of municipal fees, which are usually around 3.35% of the construction budget (PEM).
    • Major Works Licence: Required for full refurbishments or any work involving changes to the façade or structure of the building. This also requires a Technical Project approved and signed by a certified professional.

    Tips to save time and money on your renovation

    The most effective way to achieve real savings when renovating a flat or apartment is to implement strategic planning. This should go hand in hand with identifying opportunities to improve efficiency and transparency when hiring professionals and services, ensuring a solid Return on Investment (ROI).

    With this in mind, here are some key steps to follow if you want to secure a good ROI.

    Comparing quotes from several companies

    Request at least three quotes so you can compare and reduce costs. Make sure each quote includes a detailed breakdown of every task, and ask suppliers to specify clearly the cost of materials and labour.

    Renovating in phases

    Phased renovation is an excellent way to spread both time and costs, or to move forward gradually if the property is occupied. A logical order would be to prioritise electrical and plumbing installations first, followed by the kitchen, bathroom and, finally, all finishes.

    Using renovations to improve energy efficiency

    Investing in energy efficiency means saving on future energy bills. Replacing your windows with models that incorporate Thermal Break technology is essential, as up to 30% of total energy consumption can be lost due to poor insulation.

    Remember you can also apply for public grants to support these improvements, such as the programmes funded by NextGenerationEU that promote energy-efficient refurbishment of residential properties.

    Trends in flat and apartment renovations

    Current interior design focuses on maximising space, wellbeing and functionality. As a result, trends in Barcelona now revolve around creating property assets that ensure proven revaluation while delivering the highest possible quality of life.

    Modern and minimalist styles

    The leading trend combines an organic style with warm minimalism. This is achieved by using raw materials such as natural wood, neutral colours like earth tones and beige, and linen textiles to create a serene, beautifully simple atmosphere.

    Open-plan kitchens and functional bathrooms

    Open-plan kitchens connected to the living area are very much in demand, as they create a sense of spaciousness and optimise natural light in urban flats. It is also important to invest in quiet extractor hoods and good-quality appliances for greater comfort.

    In bathrooms, wall-hung sanitaryware and functional furniture are advisable to make cleaning easier and improve practicality.

    Durable, low-maintenance materials

    Large-format porcelain tiles are strongly recommended for flooring thanks to their minimal joints and high resistance, making them an excellent long-term investment. Microcement also delivers a continuous, modern finish that works particularly well in kitchens and bathrooms.

    For exterior joinery, high-performance windows with Thermal Break are essential to guarantee good thermal and acoustic insulation.

    FAQs: flat and apartment renovations

    The duration of a full renovation varies significantly depending on the size of the property and the complexity of the work. In most cases, these projects take between 3 and 6 months to complete.

    Partial renovations focused on the bathroom or kitchen are usually quicker. Their approximate duration ranges from 2 to 8 weeks.

    The answer is a definite yes. Submitting notifications and obtaining permits from the local authorities is mandatory for almost any work that qualifies as a renovation. These procedures are handled through Barcelona City Council, and failing to comply can entail a high risk of fines or even work stoppages.

    In summary, keep the following in mind:

    • Simple finishing works such as changing flooring, painting or tiling that do not alter the layout require an Assabentat (prior notification). This is a free, informative procedure that does not require a technician and can be completed online.
    • Works that involve changes to installations or layout, such as major bathroom and kitchen refurbishments or moving non-structural partition walls, require a Minor Works Permit (Comunicado de Obra Menor). This requires a qualified technician and payment of municipal fees, which are usually around 3.35% of the construction budget (PEM).
    • Full refurbishments and any changes to the façade or structure require a Major Works Licence (Licencia de Obra Mayor) and a Technical Project approved and signed by a certified professional.

    Renovating your flat in phases is perfectly possible and is, in fact, a highly effective logistical and financial strategy for spreading costs. It also helps minimise disruption if the property is occupied and avoids having to make a very large initial investment.

    For greater efficiency, you can follow this common sequence for essential work:

    • Phase 1 – Structure and installations: Prioritise safety and liveability by renewing obsolete electrical and plumbing installations.
    • Phase 2 – Key rooms: Focus on bathrooms and kitchens, as these areas have a high visual and functional impact and generally provide an excellent improvement.
    • Phase 3 – Finishes: Complete the project with decoration, painting, flooring, carpentry and related details.

    The renovations that usually deliver the highest ROI are those that improve hygiene, energy efficiency and functionality. Some of the upgrades that add the most value include:

    • Bathroom and kitchen: Renovating these spaces offers the best return in terms of quick payback, with potential increases in sale price of around 5% to 10%.
    • Energy efficiency: Investing in thermal and acoustic insulation is crucial for long-term savings. For example, windows with Thermal Break technology are ideal for reducing heat loss, and replacing traditional lighting with LED systems can cut electricity consumption by up to 80%.
    • Layout and finishes: Open-plan layouts (open concept) increase the sense of space and natural light. Continuous flooring and neutral wall colours also contribute significantly to the property’s revaluation.
    • Furnishing: While not strictly a renovation, home staging or strategic interior design based on property marketing techniques can raise the perceived value of a home. Neutral, depersonalised furniture helps potential buyers imagine themselves living there, facilitating both sales and rentals.
