Interior architect in Marbella and across the Costa del Sol
Malak Tazi designs the full layout of your apartment or villa — plans, materials, furniture, lighting — then runs the build through to handover. One person, from the first sketch to the final detail.
What does an interior architect actually do?
An interior architect does more than pick colours. They redesign the way you live in the property: moving partitions, turning a kitchen towards the light, finding a bedroom where there was only a corridor, resizing a bathroom. It is spatial planning work that touches structure, wiring and plumbing — and it results in technical drawings trades can build from without guesswork.
An interior decorator works on what is placed in the room: furniture, textiles, lighting, paint. The two trades complement each other, and Kasara covers both. But if your project involves opening a wall, rerouting services or rethinking the layout, an interior architect is what you need.
On the Costa del Sol this distinction matters twice over: properties are often built to repetitive plans, with dark living rooms and underused terraces. Most of the added value comes from redistributing space, not from decorating it.
Design meant to be built
Many projects fall apart between the beautiful render and the building site. At Kasara the design is led by the person who will then run the works: every idea is tested against feasibility, cost and the constraints of the building from day one. You do not discover at quotation stage that the scheme was never buildable.
In practice you receive a moodboard, layout drawings, a 3D visualisation, then a full construction package: partition, electrical and plumbing drawings, floor setting-out and joinery details. That package is what allows several contractors to price the same scope — and produce quotes you can genuinely compare.
Marbella, Benahavís, Estepona: a local practice
Malak Tazi trained at Penninghen and EFET Paris, and practises on the Costa del Sol. She knows the local suppliers, the real lead times in Andalusia, the constraints imposed by owners’ communities and the town hall process for a licencia de obra.
Being based here changes the nature of the service: site visits are weekly and physical, not phone calls. The trades are people she has worked with for years and accredits personally.

Design
Moodboard, layout drawings and 3D visualisation. We iterate until the scheme matches exactly what you had in mind.
- 03
Construction package
Full technical drawings and quantities. This package underpins the tender and prevents surprises once work starts.
- 04
Site supervision
Weekly meetings on site, written reports, quality control, handover and snagging.
Frequently asked questions
How much does an interior architect cost in Marbella?
The full commission — design and site supervision — starts at €85 per m². For an 80 m² apartment that is around €6,800 excluding VAT. These fees are waived if you also entrust the building works to Kasara, from €50,000 of works.
How is this different from an interior decorator?
An interior architect alters structure and services: moving partitions, redistributing rooms, renewing electrics and plumbing, and supervising the build. A decorator works on furnishing and finishes without touching the fabric of the building.
Do I need an architect to renovate an apartment in Spain?
Works affecting structure, the façade or shared services require a licencia de obra mayor with a technical project. A standard interior renovation usually falls under a obra menor declaration. Kasara tells you which applies at the first visit.
Can you work with me while I live abroad?
Yes — most of our clients do. Meetings are held by video call, the 3D lets you approve the scheme remotely, and weekly site supervision is documented with photographic reports.
Which areas do you cover?
Marbella, Puerto Banús, Nueva Andalucía, Benahavís, La Quinta, Los Flamingos, Estepona, Mijas and Sotogrande.
