Full renovations in Alella.

Priorat: a full renovation delivered in 16 weeks

Full renovation of a home in Alella, completed in 16 weeks. We worked with seamless surfaces, clean junctions between timber and plaster and climate control you cannot see. The attic floor was fitted out with a high level of insulation so it could be lived in all year round.

These are photos of the real project. On the left, the finished attic floor with skylights and built-in wardrobes. In the middle, the bathroom during the works: large-format tiles laid with levelling clips so the joints stay flat. On the right, the kitchen just fitted, days before handover.

What changes when you renovate a house in Alella

Most projects in Alella are houses, and a house brings items a flat never has: roof, roof space, façade, external joinery, drainage and often the garden and the plot's walls. That is why the quote starts from the actual house, not from a generic price per square metre.

The attic deserves its own chapter. It is the space that gains most from a renovation and the one that suffers most when insulation is done badly: cold in winter, hot in summer and condensation. In Priorat it was the most technically demanding part.

Alella sits close to the sea and Maresme humidity reaches it too. Joinery, insulation and finishes are specified with that in mind, not as if it were a dry interior.

What we check in an Alella house

How much does a renovation cost in Alella?

Indicative 2026 ranges, excluding VAT, before seeing the house:

The price moves most with the building envelope, the level of finishes and the climate system. We take on projects with an itemised quote and payment against work completed.

Building permits in Alella

The permit is filed with Alella Town Council, not with Premià or Barcelona. 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.

The construction tax (ICIO) is set by each council, up to a legal maximum of 4% of the construction budget. Before planning an extension or enclosing a porch, we check with the architect what the local plan allows on your plot. The full county guide is building or renovating a house in the Maresme.
