Luxury Villa Renovation in Sitges
Bespoke design, carefully coordinated materials and specialist solutions for owners who want their villa to feel personal—not simply new.
Discuss Your VillaSee Our Quintmar ProjectWhat Makes a Villa Renovation Truly Premium?
Luxury is not created by adding expensive finishes to an unresolved layout. It begins with how the home works, feels and connects.
We approach premium villa renovation through proportion, natural light, circulation, comfort and coherent material choices. Kitchens, bathrooms, joinery, lighting and technical systems are considered together so that the result feels intentional throughout the property.
Every proposal is shaped around the existing villa, the owner's priorities and the technical scope required.
Personalised Spaces, Integrated as One Home
Bespoke Joinery
Custom storage, integrated cabinetry and architectural details designed for the dimensions and character of the villa.
Architectural Lighting
Layered ambient, task and accent lighting that supports the architecture rather than being added as an afterthought.
Kitchen & Living
Coherent social spaces with integrated appliances, practical circulation and carefully coordinated finishes.
Wellness Bathrooms
Calm, durable bathrooms with considered lighting, storage, surfaces and spa-inspired features where appropriate.
Acoustic Comfort
Solutions for cinema rooms, entertainment spaces, bedrooms and living areas where privacy and sound quality matter.
Invisible Technology
Automation, climate control and specialist glazing integrated without compromising the visual language of the interior.
Details That Change How a Home Feels

Specialist Features for Contemporary Villas
Selected features can be incorporated when they support the architecture and the owner's priorities. They are assessed individually rather than presented as standard inclusions.
Connecting Interior and Exterior Living
In villas across Terramar, Can Girona, Vinyet, Vallpineda, Levantina, Montgavina and Quintmar, the relationship between indoor rooms, terraces, views and natural light can define the entire renovation.
Depending on the existing structure and permissions, the design may explore larger openings, aligned floor levels, shading, exterior lighting and a more continuous material palette. Structural work, façades, pools, landscaping and other exterior interventions are assessed and priced separately.
Villa Services and Indicative Costs
Bespoke Spaces Built, Not Rendered
Our Quintmar portfolio documents the work behind the finished result.
The renovation included a new kitchen, living areas, bathroom and a personalised cinema and billiard room. The full case shows demolition, installations, plasterboard, finishes and the completed interior using real project photographs.

Luxury villa renovations cannot be priced accurately from surface area alone. Bespoke joinery, specialist glazing, lighting, automation, premium materials, structural changes and the existing condition of the property can substantially affect the investment.
Coste Casa prepares quotations by work items after defining the technical scope and selected finishes—not by simply multiplying square metres by a generic rate.
All prices are stated without VAT unless expressly indicated. Architectural and technical projects, architect or quantity-surveyor site management, municipal licences and fees are not included unless the proposal expressly states otherwise. External works and hidden conditions are assessed separately.
Design Decisions Need Construction Reality
Irina and the Coste Casa team bring design conversations and on-site execution into the same project dialogue. The objective is not only to choose attractive materials, but to understand how they meet, how they are installed and how they will perform in daily use.

Premium work depends on communication, organisation and accountability as much as the finished appearance.

What is the difference between a standard and a luxury villa renovation?
A premium renovation normally involves a higher level of spatial planning, bespoke detailing, specialist materials, integrated lighting and technology, and closer coordination between design decisions and construction execution.
Can you create fully bespoke interiors?
Yes. The agreed scope may include custom joinery, kitchens, bathrooms, entertainment rooms, lighting and other personalised solutions, subject to technical feasibility and the selected project team.
Do you install Smart Glass or home automation?
These can be assessed as specialist premium options. Suitability, specification, electrical requirements and supplier scope must be defined for each property.
Can a premium renovation be priced per square metre?
A broad reference may help at an early stage, but an accurate proposal must be prepared by work items after the technical scope and finishes are defined.
Are architects, site management and licences included?
Only when expressly stated in the proposal. These professional services and municipal costs are not automatically included.
Which parts of Sitges do you cover?
Suitable projects are assessed throughout Sitges, including Terramar, Can Girona, Vinyet, Vallpineda, Levantina, Montgavina and Quintmar.
