As a guide, enclosing a terrace with glass curtains in Spain costs between €200 and €450 per square metre installed; a basic sliding aluminium enclosure is around €250-400/m² and a bioclimatic pergola €400-900/m². The final price depends on the size, the glass thickness, the opening system and how easy the site is to access, which is why only a quote based on real measurements gives you the exact figure.

Yes. In Andalusia, enclosing a terrace always requires some form of council approval: usually a declaración responsable (self-declaration) or a minor works licence, depending on each council's bylaws and on whether the enclosure changes the façade and the built area. If you live in a block, you also need the agreement of the owners' association.

To enclose a terrace in a block of flats you need the agreement of the owners' meeting: Spain's Horizontal Property Act requires a vote in favour from three fifths of the owners, who must also represent three fifths of the ownership shares. Even if only you use the terrace, the façade is a common element, so the enclosure must respect the look of the building and also needs council approval.
Read the guide (in Spanish)To enclose a terrace, glass curtains are the best option if your problem is wind, rain or noise, while a bioclimatic pergola or a retractable or fixed roof is the answer if what you need is shade or cover from the rain. If you want an extra room you can use all year round, the ideal is to combine a roof or pergola with glass curtains on the sides. During the free site visit we'll recommend the option that best suits your terrace.
As well as homes, we install glass enclosures, pergolas and roofs for residential buildings, bars, restaurants and hotels across the province of Cádiz. In blocks of flats it is common to approve a single enclosure model for the whole façade, and we provide the technical description for you to present at the owners' meeting.

Glass curtains and pergolas need little maintenance, even near the sea. Clean the curtains with water and an ordinary glass cleaner, and keep the tracks clear of the sand blown in by the levante wind. For bioclimatic pergolas, cleaning the louvres and gutters with water and mild soap a couple of times a year is enough. On the Cádiz coast, rinse off the salt with fresh water more often and, if the system is motorised, have the motor checked regularly.
