Luxury Renovations
In Costa Del Sol
Premium renovations for exclusive villas — engineered to last, executed without intermediaries.
Your villa deserves more than a renovation company. It deserves a technical team.
The most common failure in high-end renovation is not poor taste — it is poor execution.
Imperfect levelling under Calacatta marble. Moisture behind a wet-room wall. A ventilation system that never quite works as designed. These are not coincidences. They are the predictable result of fragmented teams where no single party controls the complete process.
Realta Constructions operates differently. We only take on comprehensive renovations — never partial or cosmetic works — because we believe that true quality requires full control. Our in-house team manages demolition, structural reinforcement, all MEP installations and every finish trade under a single technical direction.
The result is a residence that performs as well as it looks: waterproofed, levelled, coordinated and documented.
The Realta 7-Phase Method
Every renovation begins with a technical audit. Nothing is assumed. Everything is verified.
Every phase has a defined scope, a documented output and a clear milestone. You always know exactly where your project stands — and so do we.
This is what we mean when we say ‘turnkey’. Not a word we use loosely, but a commitment we back with a contract.
What a High-End Comprehensive Renovation Involves
A complete renovation of a luxury villa in Costa del Sol typically encompasses:
Demolition
& structural preparation
Full strip-out with controlled waste management, structural reinforcements where required, aperture of new openings with full engineering oversight.
MEP replacement
Complete renewal of electrical, plumbing and HVAC systems, replanned to meet contemporary performance and regulatory standards. All systems pre-coordinated before walls are closed.
Acoustic and waterproofing systems
Professional mass-spring-mass acoustic insulation in entertainment spaces, full hydraulic waterproofing in wet rooms. Not optional. Not cosmetic. These are engineering requirements.
Technical finishes
Laser-levelled bases for large-format porcelain (1600x3200mm), marble and natural stone. Millimetric grout lines. Inlaid LED profiles. Bespoke carpentry integration at every junction.
Smart-home and lighting
Integration of advanced domotics, HVAC zoning, architectural lighting at 2700K with concealed sensors and adjustable rail systems calibrated to each space.
Post-renovation documentation
As-built drawings, material warranties, system operating manuals and a scheduled post-delivery technical review. Your renovation is documented as thoroughly as a new build.
Why ‘Comprehensive’ Means Something Different at Realta
Most renovation companies describe their service as ‘comprehensive’ but manage it through a chain of independent subcontractors: a tiling team, a plumbing firm, a separate electrician.
Each one arrives on site, executes their scope, and leaves. Nobody owns the interface between trades — the junction between waterproofing and tiling, the coordination between HVAC ducts and ceiling height, the sequence that determines whether your floors go down before or after your skirting.
At Realta, every trade is ours. That means every interface is ours. When the tile layer finishes a wet-room wall, it is our waterproofing team that certified the substrate. When the electrician conceals a conduit in a partition, it is our site director who signed off the drawing.
This is what genuine technical control looks like. And it is the only way we know how to work.
What We Guarantee
Beyond What the Law Requires
5 years on construction finishes
2 years beyond the legal requirement under LOE. Covers levelling, tiling, carpentry, waterproofing and all finish elements executed by our own team.
10 years on structural elements
Full statutory coverage under LOE, with complete traceability through documented certifications issued throughout the build.
Monthly financial transparency
Detailed progress certifications at each billing milestone, with prior written approval required for any scope or budget modification.
Post-delivery technical review
A scheduled site visit after handover to identify and resolve any minor installation issues before they become structural problems.
We extend our guarantees voluntarily because we are confident in our execution. A contractor who refuses to guarantee their work is telling you something important.
Real-world example
A high-end residential renovation in Neuilly-sur-Seine, France — 137m², estimated investment up to €1,000,000.
The Project illustrates exactly why Realta’s methodology exists. The client approached us with a vision for a premium residential intervention — without a complete definition of materials, finishes, technical specifications or building systems. A direct ‘turnkey execution’ at that stage would have introduced exactly the risks our clients hire us to eliminate: on-site decisions, budget deviations and avoidable defects.
Instead, we proposed Phase I: Interior Design & Architecture — a comprehensive development phase combining interior design, interior architecture and full technical project definition, before committing to a single euro of construction expenditure. The outcome of Phase I was a project fully defined from an aesthetic, architectural and technical perspective, with a fixed execution budget, a realistic construction schedule and a clearly prepared turnkey contract.
This is the Realta sequence in practice:
Study and design → Fixed budget → In-house execution → Delivery and guarantee.

FAQs
Questions about renovating an existing luxury villa or high-end residence on the Costa del Sol.
What makes a renovation 'comprehensive'? Is mine eligible?
A comprehensive renovation, in our definition, means a total intervention on the property — not a cosmetic refresh or a partial update of one area. It typically involves replacing MEP systems (electrical, plumbing, HVAC), redistributing or reinforcing structure, renewing all interior finishes and integrating modern technical systems throughout. If you are considering replacing kitchens and bathrooms only, or repainting and reflooring, we would be happy to assess your project — but our expertise and model are optimised for full-scale interventions.
Can I live in the property during the renovation?
In most comprehensive renovations of the scale we work on, it is not advisable — and often not possible — to remain in the property during construction. Demolition, structural works and MEP replacement generate conditions that are incompatible with habitation. We can discuss phased execution for specific cases, but we will always give you an honest technical assessment of what is feasible rather than a commercial answer designed to ease the sale.
My property has hidden defects from a previous renovation. Can you fix them?
Yes — and this is one of the scenarios we encounter most frequently. Hidden defects from poor previous work — moisture infiltration, levelling failures, undersized electrical installations, badly waterproofed wet rooms — require proper diagnosis before remediation. We begin every renovation project with a technical audit that identifies existing defects, documents their extent and proposes the correct structural solution. We do not cover problems with new finishes. We correct them at the source.
How long does a comprehensive renovation take?
For a complete renovation of a high-end villa of 300–600m², the execution phase typically runs 6 to 14 months, depending on the extent of structural intervention, materials sourcing and custom element fabrication. The prior design and technical project phase adds 6–10 weeks. We issue a signed construction schedule at contract stage — and update it transparently if circumstances require adjustment.
Do you work with large-format stone and marble?
Yes, and this is one of our technical specialisations. Installing materials such as Calacatta, Travertino Alabastino, Sant Laurent or large-format porcelain at 160x320cm requires laser-precise substrate preparation, specialised cutting equipment, specific adhesive systems and experienced installers who understand how to handle pieces of this weight and size without damage. Our team has executed these installations across multiple high-end projects in Marbella — including works at Boho Club and private villas in La Cerquilla and QSJ.
Can I bring my own interior design concept and have Realta execute it?
Absolutely. We regularly work as the construction arm for projects whose design has been developed by external studios — including our ongoing collaboration with Pedro Pena. What we require is that the design is sufficiently detailed and technically resolved for us to price and execute with precision. If the design is still at concept stage, we recommend completing the technical project phase before signing a construction contract — this protects both you and us from costly ambiguity.
What does the technical audit before renovation include?
Our pre-renovation technical audit covers: assessment of the existing structural condition, identification of hidden defects and moisture pathways, review of current MEP installations and their compliance with current regulations, evaluation of the acoustic and thermal performance of the building envelope, and a preliminary scope estimate. The audit forms the technical basis for the project definition and execution budget that follow — nothing is assumed, everything is verified on site by our own engineers.
