Building or Renovating a Villa in Marbella & Costa del Sol: Complete 2026–2027 Guide

Building or renovating a villa in Marbella and the Costa del Sol is an opportunity to create a property tailored to modern Mediterranean living while potentially increasing the value of a home in one of Southern Europe’s most desirable residential markets.

However, a successful villa renovation involves much more than choosing finishes and creating a new interior design. Planning permission, technical design, construction management, materials, installations, energy efficiency, budgeting and coordination between different trades all play an important role.

In this guide, we explore the key aspects to consider before starting a villa renovation or construction project in Marbella and the Costa del Sol.

Renovating an Existing Villa vs Building a New One

One of the first decisions is whether to renovate an existing property or develop a new villa from the ground up.

Renovating can be particularly attractive when an existing property already has three valuable assets: a good plot, an established location and exceptional views.

Areas such as Marbella, Nueva Andalucía, Benahavís, Elviria, Sierra Blanca, Mijas, Benalmádena and La Capellanía have many established villas with excellent locations that can be completely transformed through a carefully planned renovation.

Opening interior spaces, installing larger windows, upgrading electrical and plumbing systems, redesigning terraces, renovating swimming pools and introducing contemporary materials can dramatically change both the appearance and functionality of a property.

New construction, on the other hand, provides the freedom to define the architecture, orientation, distribution, installations and materials from the beginning.

Planning Permission and Building Licences in Marbella

Before starting construction work, it is essential to determine which administrative procedure applies to the project.

Depending on the type and extent of the work, different permissions or procedures may be required.

Structural modifications, extensions, significant façade alterations and major exterior works can require different approvals from smaller internal renovations.

For this reason, assessing the property and clearly defining the scope of work before construction begins is an important part of the process.

Proper planning at this stage can help prevent unnecessary delays and unexpected changes during construction.

How Much Does It Cost to Renovate a Villa in Marbella?

There is no single price per square metre that accurately represents every renovation.

The final cost depends on several factors, including:

• Size and current condition of the property

• Quality of materials and finishes

• Structural modifications

• Electrical and plumbing installations

• Air conditioning and heating systems

• Windows and exterior doors

• Kitchens and bathrooms

• Swimming pool and exterior areas

• Landscaping

• Architectural complexity

• Site accessibility and construction logistics

In high-end villa renovations, choices involving natural stone, glazing, carpentry, lighting, kitchens, climate systems and bespoke finishes can significantly influence the final investment.

For this reason, a detailed construction budget divided into individual work packages provides considerably more control than relying exclusively on a generic cost-per-square-metre estimate.

Villa Renovations That Make the Biggest Difference

The most successful transformations go beyond simply replacing finishes.

Architecture, construction, installations and design should work together to create a coherent property.

Open-Plan Living

Connecting the kitchen, dining room and living areas can dramatically increase the feeling of space and allow natural light to travel throughout the property.

Indoor–Outdoor Living

The Mediterranean climate makes exterior spaces an essential part of life on the Costa del Sol.

Large sliding glass doors and open-plan layouts can connect living areas directly with terraces, gardens and swimming pools.

Terraces and Swimming Pools

Outdoor spaces are particularly important for villas in Marbella.

Pergolas, outdoor kitchens, renovated swimming pools, contemporary terraces, architectural lighting and landscaping can completely transform how a property is experienced.

Energy Efficiency

A comprehensive renovation also provides an opportunity to improve the property’s energy performance.

Modern insulation, efficient windows, aerothermal systems, solar panels, LED lighting and smart energy management can improve comfort while reducing energy consumption.

Smart Home Technology

Modern villas increasingly incorporate intelligent systems for lighting, climate control, blinds, security, access control and energy management.

Integrating these technologies during the renovation process is generally easier than adding them once construction has been completed.

Planning Is the Key to a Successful Renovation

One of the most common causes of delays and budget deviations is beginning construction before enough decisions have been made.

Before starting a comprehensive renovation, it is advisable to define the main aspects of the project, including:

• Final layout

• Technical design

• Main materials

• Electrical and plumbing installations

• Lighting

• Windows and doors

• Kitchen and bathrooms

• Exterior areas

• Detailed construction budget

• Estimated construction schedule

The more decisions that are made before construction begins, the greater the level of control throughout the project.

Turnkey Construction & Renovation in Marbella

A comprehensive villa renovation can involve architects, engineers, builders, electricians, plumbers, HVAC specialists, carpenters, painters, pool contractors, landscapers and numerous material suppliers.

Coordinating these different teams is therefore a fundamental part of delivering a successful project.

This is particularly relevant for international property owners who may not live permanently in Spain and require a reliable local team to manage and coordinate the work.

At A28 Group, we carry out construction and renovation projects in Marbella and across the Costa del Sol, coordinating the different stages required to transform each property.

Our objective is to provide an organised construction process with clear communication and continuous project monitoring from the initial planning stages through to completion.
