Interior Design Studio in Sitges · Barcelona

The leading studio
in el Garraf


The go-to interior design studio in el Garraf, specialising in exceptional residences with a Mediterranean Quiet Luxury sensibility

At Mercè Rafecas Interiors, we work with homeowners embarking on new builds or comprehensive renovations along Barcelona’s southern coast.


A complete home involves hundreds of decisions, constant coordination and a clear aesthetic vision from day one. Our studio is here to make that process seamless, precise and, we believe, genuinely enjoyable.

From Sitges, we take your new luxury home to an exceptional level.

We create elegant, warm, timeless interiors that let you live at ease. You get an outstanding result; we take the complicated decisions off your hands.

An interior design studio in Sitges dedicated to full-scope projects on Barcelona’s southern coast

Our interior architecture service ensures your new home lives up to the investment you’ve made.

This isn’t about mixing colours, textures and furniture. It’s about building a home that works beautifully, moves you emotionally and holds its elegance for years to come.

We take 1,001 complex decisions off your plate. Our proven methodology guarantees coherence from the first sketch to the final detail.

Who is Mercè Rafecas?

Interior architect, furniture designer, Master’s in Lighting Design, and founder and CEO of Mercè Rafecas Interiors. For 15 years, Mercè and her team have been creating exceptional homes in Sitges, Barcelona and across el Garraf.

“For me, residential interiors go far beyond aesthetics. A home should improve your daily life, bring serenity and reflect who you are. I always start by listening, then shaping spaces around light, order and authenticity.

Living well at home means stepping out of the rush. Not going slower, but working with clarity, rigour and the right rhythm, so that a process full of decisions becomes agile, light and coherent. That’s how we work.

I grew up steeped in a visual culture rooted in the Mediterranean. It’s home. That contemporary, warm, understated sensibility shapes how we think about materials, light and function, and how we weave in technology with subtlety, always in the service of wellbeing.

My vision of interior design isn’t about ‘decorating’. It’s about creating life experiences. We look for the balance between beauty and function, emotion and tangible value, so that every home breathes calm, moves at your pace and stands the test of time.”

OUR SPECIALISATION

Mediterranean Quiet Luxury: homes that breathe light and authenticity

We design in a contemporary Mediterranean register that puts wellbeing, visual clarity and a connection with the outdoors ahead of decorative excess or gadgetry.

Just as important: every client should recognise themselves in their home. The design must reflect how you actually live, effortlessly.

Mediterranean Quiet Luxury is our everyday language. A discreet, warm luxury that raises your quality of life without ever demanding attention. Your exceptional home on Barcelona’s southern coast becomes the place you most want to be. Your private oasis.

METHODOLOGY

How we work: from concept to handover

Our five-phase methodology ensures your luxury home turns out exactly as you envision it. We take 1,001 decisions off your shoulders, maintain coherence across every space and minimise the risk of costly mistakes.

1 | Alignment Session

We sit down to understand how you live and what you value most. Together we define the essentials: function, wellbeing, aesthetic direction. Then we map out a plan with clear milestones.

Your role: tell us how you live and what matters. We handle the rest.

2 | Curated Options

We integrate with your architect to optimise the layout and guarantee coherence. Then we prepare 3D visualisations and refined proposals so you can see the outcome before committing. Every alternative is carefully selected, so decision-making becomes comfortable and manageable.

Your role: choose what feels right, without sifting through hundreds of options.

3 | Synergy with Architecture

We work alongside the architecture team and site management to keep technical and aesthetic decisions in step. We review key details and flag anything that could affect the end result, always absorbing the complexity so it doesn’t land on you.

Your role: approve key decisions through short, clear updates.

4 | Procurement & Logistics

We manage budgets, orders and timelines with trusted suppliers. Where appropriate, we prioritise noble, locally sourced materials, and maintain full traceability, including on international purchases.

Your role: sign off on major purchases, with all the information already distilled.

5 | Installation & Handover

We oversee every installation, every styling detail, every quality check. Each piece is inspected on-site so that when you open the door, the home is ready to enjoy from day one.

Your role: walk in and start living.

Working with your architect

On new builds, the partnership between architect and interior designer is essential. The architect sets the structure, proportions and relationship with the landscape. We define the internal layout, then continue refining circulation, materials, built-in furniture and lighting, turning spaces into a home that truly works.

When you find a collaborator you can work with fluidly, with shared standards and real trust, you keep coming back. Mercè Rafecas Interiors is clearly that partner for high-end architecture and interior design.

Their interior design service has been key to bridging the gap between drawing and reality. It made the build far smoother and gave the client real peace of mind. Decisions were well defined, budgets transparent, and the whole process felt more ordered and less tense.

WHO WE WORK WITH

Projects that fit our studio

Not every project calls for a specialist architecture and interior design studio. Ours makes the most difference in exceptional homes where the priorities are quality, sound judgement, delegation, agility and aesthetic coherence.

Ideal projects

✔ Detached homes in Sitges, Castelldefels and el Garraf
✔ Primary or secondary high-end residences
✔ Comprehensive renovations, full scope
✔ Projects where we join from the initial design phase
✔ Clients who value quality, precision and timeless design

Not for us

✘ Partial projects (kitchen only, bathroom only)
✘ Styles far removed from Mediterranean Quiet Luxury
✘ Unrealistic timelines
✘ Budgets that don’t allow for quality materials

Clients already celebrating a home designed to the last detail


An outstanding team: professional, attentive and a pleasure to work with. I’m delighted with both the finished result and the tradespeople they brought in. They hit every deadline, even though I kept adding to the scope, and stayed within budget, which matters enormously. I’ve already recommended them to several friends.
