What the options are and what decides the choice
For a detached house in the province of Barcelona there are six realistic families: render (including the top coat of an ETICS insulation system, known locally as SATE), natural stone, ceramic or porcelain on a ventilated rainscreen, timber, composite or fibre-cement panels, and facing brick. Three things decide it: the site’s climate and exposure, how much maintenance you are willing to take on, and how the cladding works with the wall insulation.
How to make facade decisions for the house as a whole, from windows to roof junctions, is covered in a separate guide. This one is about materials and how they age.
Render and ETICS
This is the most common choice for new houses here: insulation fixed to the outside of the wall with a thin reinforced render coat on top. The advantages are clear: insulation without thermal bridges, a uniform look, a moderate price. So are the drawbacks: the thin coat dislikes impacts at body height, and dark colours on a sunny elevation get very hot, so system manufacturers restrict the shades you can use. Check this before you fall for anthracite.
Traditional render straight onto brick without external insulation costs less, but the CTE energy requirements for a new house then have to be met another way, usually by insulating from inside.
Stone and ceramic
Natural stone is fixed in one of two ways: bonded, when the pieces are thin and small, or on mechanical anchors with a cavity, when the slabs are large. The second costs more, but a slab cannot come away because the adhesive has fatigued. Above head height we prefer mechanical fixing.
Porcelain on a ventilated rainscreen works in a similar way: panels on a subframe, with an air gap and insulation behind. It needs almost no maintenance, copes well with sun and allows large formats. It costs more than render, and the window junctions must be drawn in advance: a rainscreen adds wall thickness, so reveals end up deeper.
Timber, composite and panels
Timber brings a warmth no other material matches, but under our sun it changes quickly. The choice is simple: either renew the oil or stain regularly, typically every one to two years on the south side, or accept from the start that the boards will turn silver-grey. Both are fine; the only bad option is choosing neither.
Composite and thermally modified timber need less care but look flatter and more artificial up close. Fibre-cement and HPL panels give crisp geometry and a wide colour range. With every panel system the weak points are the joints and fixings: see them on a sample, not just in a render.
Houses by the sea: Castelldefels, Garraf, Maresme
Sea air carries salt, and salt finds every weak detail. Rainscreen fixings and stone anchors near the coast should be stainless steel of a suitable grade, not galvanised. Powder-coated metalwork needs proper preparation, or within a few years rust appears along the edges.
The south facade of a house in Castelldefels gets sun almost all day; the north one gets salt and wind with no sun to dry it. The same material therefore ages differently on two sides of one house. Sometimes it makes sense to use a tougher material on the sea-facing side and the one you like best on the garden side.
What happens at five and ten years
Before you choose, ask the supplier for a maintenance schedule, not just the price per square metre. Render: washing and, over time, repainting; chipping at the base is avoided by doing the bottom 50–60 cm in stone or ceramic. Stone: checks on anchors and joints, water-repellent treatment as the manufacturer advises. Ceramic rainscreen: little more than washing. Timber: oil on schedule, or natural greying. Panels: checks on fixings and seals.
Also think about access. A two-storey house with a wall rising above the pool and no room for a lift platform turns a simple wash into a separate operation.

Our project archive has photos of the facade of the house with a pool that we built from start to finish between 2022 and 2024, during the works and completed. If you are building a house, send us the project or a sketch and the plot address: we will go through cladding options against exposure and insulation and quote after a site visit. We reply within an hour.
