Full renovation · AlellaPriorat
A home fully renovated in 16 weeks, with an attic floor.
See the project →Montgat and El Masnou are the gateway to the Maresme from Barcelona: flats near the sea, houses on the higher ground and street-level commercial units. In Montgat we handed over a turnkey dental clinic in September 2026, designed by G44. We run our projects from our office in Premià de Mar.
Full renovation of a commercial unit in Montgat to turn it into a dental clinic, designed by the G44 studio and handed over in September 2026. We delivered the façade, reception, waiting room, treatment rooms, sterilisation room and every technical installation.



A clinic needs far more services than a home: supplies for every treatment room, suction, treated air and lighting that does not dazzle. All of it sits behind flush joinery and seamless walls, with a stone-textured counter at reception. Photography: Arnau Puig.
Many projects in Montgat and El Masnou are 1960s and 1970s flats near the sea. They usually still have their original services, joinery without thermal breaks and walls worn by salty damp. In a flat the works also share the building with the neighbours: hours, lift use and protection of common areas are agreed before starting.
The higher parts of both towns have detached houses, many on sloping plots. There the roof, façade, plot walls and access for materials come into play, as elsewhere in the Maresme.
Commercial units have their own list. Besides the works, the business activity has to be filed with the council, and services weigh more in the budget than finishes. At the MÜN clinic that was the most demanding part.
| Item | Why it matters here | What we do |
|---|---|---|
| Services | Original electrics, downpipes and plumbing in 50-year-old flats | Complete new, certified installation |
| Damp and salt | Closeness to the sea and exposed façades | We find the source, treat it and choose suitable finishes |
| External joinery | Heat loss and traffic noise | Thermally broken frames with good acoustic insulation |
| Owners' association | Hours, lift and common areas | Works plan and protection agreed with the neighbours |
| Commercial units | Activity licence, accessibility and technical services | Coordination with the design and the activity filing |

The permit is filed with the council of the town where the works take place, Montgat or El Masnou. If the work touches structure, façade, roof, volume or use, a major works permit with an architect's project is the norm. Interior-only renovations usually go through a prior notice for minor works.
For a commercial unit, the activity filing comes on top of the works. The construction tax (ICIO) is set by each council, up to a legal maximum of 4% of the construction budget.
We measure and check structure, services, damp and access.
Every chapter measured and priced, so you know what you pay for and can decide in phases.
Completion guarantee with a penalty for delays. We coordinate the permit with your architect.
Coordinates the trades and certifies progress every week on your tracking panel.
Final walkthrough, project documentation and written guarantees.

We run Montgat and El Masnou projects from Carrer Gibraltar 44, Premià de Mar. The office holds tile, joinery and finish samples so you can choose with the material in front of you.
Other projects run from Premià de Mar in nearby towns.

Yes. The MÜN clinic in Montgat is one example: we coordinate the architect's design, the technical services and the complete works through to handover.
It is filed with Montgat or El Masnou council. If the work touches structure, façade, roof, volume or use, you need a major works permit with an architect's project. A commercial unit also needs the activity filing.
At Carrer Gibraltar 44, Premià de Mar, about 15 minutes' drive from Montgat and El Masnou. We are open Monday to Friday from 8:30 to 18:00, and the first visit takes place at the property.
