Júlia Brunet is an interior design studio in Barcelona, led by Mireia Torruella, specialising in apartments in the Eixample and the upper city.
Júlia Brunet is a boutique interior design studio in Barcelona, rooted in graphic design, with more than 100 residential and commercial projects since 2011. Mireia Torruella and Joseba Astelarra handle design and construction under the same criteria, without subcontracting it to third parties.
We work on apartments, houses, farmhouses and commercial spaces in Barcelona and throughout Catalonia, following our own eight-stage method: from the first meeting to the handover of keys.
We favour honest materials and the architectural history of each space, combined with contemporary design.
Júlia Brunet was born in 2011 as a graphic design studio, founded by Mireia Torruella. Over time it moved towards interior design: today it is a boutique interior design studio in Barcelona, with more than 100 residential and commercial projects in Barcelona and throughout Catalonia.
The name is not a person: it is an alter ego. Júlia is Mireia’s daughter; Brunet, her grandmother’s surname: roots, evolution and continuity.
Founded as a graphic design and communications studio.
Mireia begins the Degree in Interior Design at BAU.
A boutique studio with a limited number of active projects.
Mireia grew up in a family connected to furniture: her father a manufacturer, her mother running a design furniture shop.
A stable team of two interior design experts on every project: Mireia leads the design and the client relationship; Joseba takes care of the technical project and the construction work.

ARCHITECT · TECHNICAL PROJECT AND CONSTRUCTION
Mireia’s training in composition, colour and visual hierarchy brings a reading of space that few interior design studios have.
We bring out the original architecture of each space (mouldings, ceiling roses, nolla mosaic, original joinery) and combine it with contemporary design.
We don’t subcontract judgement: Mireia and Joseba lead the site management from start to finish, without taking on contractual responsibility for the build.
We limit our portfolio of active projects so we can be involved at every stage, from the initial design to the handover of keys.
Our interior design process has eight stages: from the first meeting to the drawings, taking in material selection and the handover of keys.
We favour honest materials that age well: natural wood, stone, lime and fine textiles.
We get to know the client, how they live and what they want: rather than talking about styles, we understand how they want to live at home.
Services included, fees and schedule, all set out before we start.
We visit the property to gather all the baseline information for the project.
Layout, concept and identity of the project, with 3D visualisations when the project calls for them.
Construction drawings, technical details and coordination with the trades.
Finishes, lighting, kitchen, bathrooms, furniture and detailing defined together with the client.
Regular site visits to check that the build matches what was designed.
We coordinate the final installation and hand over the space ready to live in.
Full interior design and decoration projects for homes and commercial spaces in Barcelona and Catalonia.
Featured in CasaViva, ELLE Decoration, HOLA, Nude Interiors, Manera Magazine, La Vanguardia and Proyecto Contract, as well as the programme Casa a Palacio. Nominated for the Superluna Awards by IDE with the Casa Masnou project.

Gràcies, Mireia, perquè ets un referent en el món del disseny i l’interiorisme. Una gran professional i millor persona que es mereix tots els è…
No podem ser més fans de l’estudi d’interiorisme que ens va salvar la vida! Professionals, creatius i amb el millor gust per fer les coses ben fetes. Top.
Molt content amb el resultat i la feina feta. Molt recomanat. Feu una visita per les seves oficines, quan coneixes la Mireia tot és molt fàcil!
We don’t offer it separately: design, material selection and site management always go together, under the same criteria from start to finish.
Mireia and Joseba lead the works directly, coordinating on each project with the specialist trades who carry them out.
Yes. We don’t stop at the layout: we select and design the furniture as part of the same project.
A decorator works on the finish; an architect, on the structure. An interior design studio like ours brings both together, with design and architecture under one team.
No. The project fee covers design, technical documentation and site supervision. Materials and furniture are the client’s responsibility; we advise on the selection and manage orders with our suppliers.
Tell us what you have in mind: layout, materials or furniture. The first conversation comes with no obligation.
