Commercial space renovation in Barcelona

Interior design, stamped technical project, licensing with Barcelona City Council and works under one point of contact. In Barcelona the opening date is set by the permit file, not by the building work.

A commercial fit-out in Barcelona runs on two parallel calendars: the works and the administrative file. Signing a lease before knowing which licensing regime the activity falls under usually means paying two to five months of rent on a unit that cannot open.

We deliver the whole unit — interior design, stamped technical project, filing with Barcelona City Council and construction — so the opening date becomes a business decision rather than a consequence of paperwork.

Licences and filings before touching the unit

The applicable regime depends on the activity, floor area and occupancy. These come up in practically every commercial project in the city.

Prior notification vs. activity licence

Low-impact activities (retail without a kitchen, offices, professional practices) are usually cleared through prior notification; hospitality, public-assembly uses or high occupancy require an environmental or recreational licence, with very different timelines and technical reports.

Works: notification or major works permit

Touching structure, façade, slab or volume shifts the regime from notification to major works permit. It is the single decision with the greatest impact on the calendar, and it is taken at the first technical survey.

Terrace and signage by-laws

Street terraces and façade signage are filed separately from the interior; in Ciutat Vella and protected axes there are design constraints best resolved at design stage.

Units in listed buildings

In Eixample, Gràcia and Ciutat Vella, listed façades or protected interior elements are common, which adds a heritage report to the file.

Accessibility and means of escape

The project must document an accessible route, an adapted toilet where required and escape routes under CTE DB-SI and DB-SUA. This is the most frequent cause of requirements and delay.

What a full commercial fit-out includes

Survey and feasibility diagnosis

Condition of services, contracted electrical capacity, fume extraction route, clear height and structural constraints. It determines what is feasible before the lease is signed.

Interior design and spatial branding

Layout, customer journey, lighting, materiality and translation of brand identity into the physical space.

Technical project and site supervision

Stamped documentation, activity report, services drawings and site supervision through to the final certificate.

Building services

Power, HVAC, ventilation and extraction, fire protection, plumbing and data. In hospitality, the duct run to roof level is usually the make-or-break constraint of the unit.

Bespoke joinery and furniture

Counters, display units, bars and storage manufactured to measure with the same workshops we use on high-end residential projects.

Realistic timelines end to end

Design and documentation: 3 to 6 weeks

From survey to a project ready to file, with design decisions closed.

Permitting: 2 weeks to 4 months

A prior notification for a low-impact activity allows a start within weeks; a licence with sectoral reports or a listed building is measured in months.

Construction: 6 to 16 weeks

An 80–120 sqm retail unit with no structural change typically takes 6–10 weeks; hospitality with a kitchen and roof extraction, 10 to 16.

Commissioning

Final certificate, legalisation of installations, utility connections and final inspection before opening to the public.

Retail or office fit-out (mid-high specification)€600 – €1,200 / sqm

Indicative ranges to test feasibility before signing a lease. The fixed quotation follows the technical survey of the unit.

Frequently asked questions

How much does a commercial fit-out cost in Barcelona?

Between €600 and €1,200 per sqm for retail and office at mid-high specification, and between €1,100 and €2,000 per sqm for hospitality with a kitchen and roof extraction. Technical project, permitting and site supervision are additional.

How long does an activity licence take in Barcelona?

A low-impact activity filed by prior notification allows a start within weeks. An environmental or public-assembly licence with sectoral reports is measured in months. The regime depends on activity, floor area and occupancy.

Do I need a major works permit?

Only if structure, slab, façade or volume is altered. Internal layout, services and finishes are usually cleared by works notification, a far faster route.

Can I open a restaurant in any unit?

No. It depends on how the activity is zoned at that address, whether the extraction duct can physically reach roof level and on acoustic compliance towards the flats above. That is the first check we run before a lease is signed.

What about the terrace and the sign?

They are filed as separate cases from the interior and carry their own design constraints, especially in Ciutat Vella and protected axes. We fold them into the project so they do not fall outside the programme.

Can you handle everything, including construction?

Yes. We work turnkey: interior design, technical project, permitting, construction and commissioning, with one point of contact and monthly certifications against work actually executed.
