Home fully renovated in 16 weeks, with an attic, bespoke joinery and seamless finishes.
See the project →Our technical office is in Premià de Mar, at Carrer Gibraltar 44. From here we manage renovations in the town and the rest of the Maresme, with an itemised budget and online project tracking for every client.
Many companies that do renovations in Premià de Mar work from Barcelona or from elsewhere in the area. We are based in the town, and that shows in the day-to-day running of the project.
The first visit, the measurements and the site meetings are all run from the office. The technical lead who prepares your quote is the same person who then manages the work and certifies progress every week.
We also know the procedures of Premià de Mar Town Council, whose online portal handles prior notifications for minor works and major works permits. Before quoting we confirm which one applies, because the procedure determines the real start date.
And every client has access to their project tracking dashboard: photos, certifications, payments and documents kept up to date. You pay for the work completed and you see it before you pay.
The housing stock in Premià de Mar is very varied, and each type has its weak points. This is what we check on the first visit:
| Home | Typical features | What we check |
|---|---|---|
| Terraced house in the old town | Ground floor plus one or two storeys, load-bearing walls and old floor slabs | Condition of beams and floor slabs, rising damp on the ground floor, roof |
| Flat from the 1960s or 1970s | Compartmentalised layout, original services | Beams (ruling out high-alumina cement), complete electrics and plumbing, downpipes |
| Home near the sea | Exposure to salt air and damp | Joinery with thermal breaks, hardware and mortars suitable for coastal areas |
| Commercial premises or office | Change of use or complete refurbishment | Activity licence, accessibility, services and façade |
In homes built between the 1950s and the 1970s we always confirm that the beams are not made of high-alumina cement. It is a simple inspection that avoids surprises once work has started. For commercial premises and offices we have a separate page: office and commercial premises renovation.
Guide ranges for 2026, before seeing the property. They include materials and labour, excluding VAT.
| Type of work | Indicative price | Construction time |
|---|---|---|
| Full flat renovation | 900–1,200 €/m² | 3 to 5 months |
| Full renovation of a house including the envelope | 1,200–1,600 €/m² | 4 to 8 months |
| New-build detached house | 1,800–3,500 €/m² built | 10 to 18 months, plus permit |
What moves the price most in Premià is the condition of the structure in older houses, the external joinery and the heating and cooling system. The item-by-item breakdown is in the 2026 full renovation price guide.
Our office is at Carrer Gibraltar 44. We come to see the property before giving a price and reply in less than 24 hours.

Premià de Mar Town Council has two routes, and it is worth knowing which one applies before asking for quotes:
If your project needs an architect, we can work with yours or introduce you to the studio we share an office with at Gibraltar 44. More detail in the guide building or renovating a house in the Maresme.
We measure the property, check the structure and services and see which municipal procedure applies.
Each section with its measurements and its price. No open-ended items such as “miscellaneous”.
Fixed schedule in the contract with a penalty for late completion. We handle the prior notification or support the major works permit application.
A single site manager coordinates the trades. Every week we certify the work completed and publish it on your dashboard.
Final inspection with you, project documentation and written guarantees.

The office is also a showroom. Here we choose tiles, joinery and finishes with you, with the material in front of us, and go over plans on the table.
If you live in Premià, the easiest thing is to drop by one afternoon with the plans or some photos of the property. If you prefer, we go straight to see it.
These are recent projects managed from the Premià de Mar office, in neighbouring towns in the Maresme and Barcelonès Nord.

View project →In 2026, a full renovation of a flat in Premià de Mar ranges from 900 to 1,200 €/m², and that of a house including the roof, façade or external joinery from 1,200 to 1,600 €/m². The exact price comes from the survey and the itemised budget.
If the renovation is interior and does not affect the structure, façade or roof, a prior notification for minor works to Premià de Mar Town Council is normally enough. If the structure, façade, roof, volume or use is affected, you need a major works permit with a project signed by an architect. We check this before quoting.
A complete flat usually takes 3 to 5 months of work. A terraced house including the envelope, 4 to 8 months. The permit period is added before the start, and we fix the schedule in the contract with a penalty for late completion.
Yes. We are at Carrer Gibraltar 44, Monday to Friday from 8:30 to 18:00. There we go over plans and material samples. Book the meeting in advance so that the technical lead who will run your project is there.
Yes. Premià de Dalt is a few minutes from the office and we work throughout the Maresme, from Montgat to Mataró. You'll find the information in renovations in Premià de Dalt and renovations in the Maresme.
