Renovating a property in Spain? One of the first questions is: do I need an interior designer, an architect or a contractor?
An interior designer creates the vision for the finished space and coordinates its execution through a network of trusted suppliers; an architect handles regulated technical work and planning requirements; a contractor executes the works. For larger renovations, all three often work together.
An interior designer focuses on how your home functions, feels and looks.
This can include:
If you have bought a villa in Marbella and want to redesign the interiors without major architectural changes, an interior designer is often the natural place to start.
The terminology can be confusing.
Interior Decorator → focuses primarily on furniture, colour, textiles, accessories and styling.
Interior Designer → works more broadly with space planning, layouts, lighting, materials, kitchens, bathrooms, furniture and the complete interior concept.
Interior Architect → generally describes a professional with a stronger focus on the spatial and architectural aspects of interiors. The title alone does not automatically mean that the person is a qualified architect in Spain.
Deeper architectural knowledge can be particularly valuable for complex renovations, but structural changes and regulated architectural work must still be handled by a professional appropriately qualified to perform that role in Spain.
An architect becomes particularly important when your renovation affects the architecture or structure of the property, such as:
In Spain, architect is a regulated profession. For projects requiring an architect, check that the professional has the appropriate qualifications and ability to practise in Spain.
Local experience is particularly valuable: your architect may need to deal with technical documentation, planning requirements and municipal procedures as part of the project.
For larger renovations, the architect and interior designer can work together — combining the architectural and technical solution with the interior concept.
The contractor executes the works, coordinating construction and trades — from demolition and building work to flooring, plumbing, electrical installation, tiling and painting.
For international homeowners, local knowledge can be just as important as a good portfolio.
Interior Designer:
Look for a strong design vision and knowledge of the local market, with established connections to trusted suppliers, craftsmen and showrooms.
Architect:
Check their professional qualifications and, importantly, their knowledge of Spanish regulations and local municipal procedures. Being able to work confidently in Spanish is particularly valuable when dealing with authorities and technical documentation.
Contractor:
Focus on proven quality of work, references, transparent pricing and a reliable team of trades.
For a substantial villa renovation, the ideal team is often:
Interior Designer + Architect + Contractor
Who to contact first depends on the project. If the renovation is primarily driven by the interior, start with an interior designer. If it involves major structural or architectural changes, start with an architect.
Either way, bringing the team together early helps align the design, technical requirements and construction.
