Here are the seven steps to building a house in Spain, in the order they actually happen.
Finding a house that already suits the way you live is harder than the portals make it look. Many buyers on the Costa del Sol end up refurbishing anyway: first you pay for somebody else’s decisions, then you pay again to undo them.
Building from scratch avoids that. What it does not avoid is the process, and the Spanish process is not the one you know from the UK or northern Europe. Different consents, different professionals, a different running order. Working with an architect who deals with local town halls every week — Juan Goñi, architect in Málaga, and his team — is usually what separates a build that runs from a build that stalls.
So, in order, the steps to building a house in Spain as we run them at Klic Arquitectos — from the plot to the keys.
The seven steps to building a house on a plot of land
1. Study the plot, then buy it
Everything sits on the land. Choosing it is the first of the steps to building a house and probably the one that matters most. It sets the size and shape of what you can build, but also the things people notice later: the slope, the orientation, and therefore how much you will spend on insulation and cooling. In an earlier post we explained how to split a plot (segregar una finca).
The bigger question is planning. Every plot carries a classification under the municipal plan (PGOU), and that classification can limit height, footprint, buildable floor area, setbacks and even the materials you are allowed to use. This is where foreign buyers tend to get caught out: land marketed as urbanizable is not the same as land classed urbano and ready to build on. Before you sign anything, have an architecture practice in Málaga run the checks — planning rules first, then ground conditions and topography.
2. The design and the project
With the plot secured, the design starts. Sit down with the architect and talk about what the house has to do: number of storeys, number of bedrooms, how the layout works, how you want it to look. This applies whether you are building a single house or multi-family housing.
The architect then works up the design, and once you have approved it, it is turned into the formal project. Two documents, in practice: the outline project (proyecto básico), which is what goes to the town hall for planning permission, and the detailed technical project (proyecto de ejecución), which is what the builder prices and builds from. Nothing moves — neither the licence nor the mortgage — until those exist.
3. Planning permission and the rest of the consents
Of all the steps to building a house in Spain, this is the one that tests your patience. Planning permission (licencia de obras) is granted by the town hall, not by a regional or national body, so the timetable depends on the municipality you happen to be in. The municipal architect and the council’s technical staff check that the project complies with the local plan and with Spanish building regulations (the Código Técnico de la Edificación, or CTE).
Once the works licence is in hand, the smaller permits follow: access for machinery, a skip on the public highway, occupation of the pavement. Individually trivial. Collectively, enough to hold up a start date if nobody has asked for them in advance.
4. Finance
You can start the conversation with the bank early, but the self-build mortgage is not signed until the works licence has been granted. Spanish lenders want the consent before they lend against the build.
The land itself is usually bought with a personal loan, which is then absorbed into the mortgage once the project has been approved. Worth budgeting for: there is a period where you are carrying both.
5. Construction
On a single house, the owner is normally also the developer (promotor) in the legal sense. That matters more than it sounds. It means responsibility for legal and health-and-safety matters is shared between you and the contractor, not parked entirely with the builder.
So choose the contractor properly. Ask around, check completed work, get more than one quotation — and ask for a programme with dates, not only a price. A quote without a programme is half an answer.
6. Interim certificates
Work is certified as it is built. The quantity surveyor (aparejador or arquitecto técnico) issues the interim certificates against the milestones and delivery dates agreed in the contract, and those certificates are what release the payments.
At the end comes the completion certificate (certificado final de obra), signed by the architect and the quantity surveyor. That is the document that finishes the house in technical and legal terms, whatever the state of the garden.
7. Registration and the first occupation licence
With the completion certificate, the house is registered at the Cadastre (catastro), the tax register that records what exists and where — not to be confused with the Land Registry (Registro de la Propiedad), which records who owns it. Both need updating.
Then back to the town hall for the first occupation licence (licencia de primera ocupación). Without it you cannot connect gas, electricity or water. It is the last box to tick, and it is the one people forget to budget time for.
Those are the seven steps to building a house in Spain. None of them is difficult on its own. The trouble almost always comes from taking them out of order — committing to a plot before knowing what can be built on it, or agreeing a build price before there is a project to price. If you are weighing up a plot on the Costa del Sol, that first check is the conversation worth having, and it is a short one.
