Why Spain is different for us
Every other page in this section describes a project run across a border. This one does not. Spain is where the company is, where the factory is, and where our own assembly teams work — which changes the project in ways that are worth being concrete about rather than simply calling it an advantage.
There is no customs clearance, no sea leg and no foreign escort regime, so the delivery is a domestic road movement measured in hours rather than a logistics operation measured in weeks. The licence application is filed by people who file them every month in the same regions, in their own language, to authorities they already know. The site supervision is done by our staff rather than by a subcontractor we have never worked with. And when something needs deciding at short notice — a foundation detail once the ground is open, a change the town hall asks for — one organisation decides it, in one language, without a chain of intermediaries.
The honest counterpoint: being local does not make Spanish bureaucracy fast, and it does not make a badly classified plot buildable. Those two things are the subject of most of this page.
The building licence and the planning classification behind it
A new dwelling in Spain requires a licencia de obra mayor from the town hall of the municipality where the plot sits. It is granted on the basis of a complete technical project, signed by an architect and stamped by the professional college, which demonstrates compliance with the Technical Building Code and with the municipality's own planning rules. A factory-built house needs exactly the same licence as a house built brick by brick on site: Spanish law licenses the building, not the method of assembly. Any supplier suggesting otherwise is describing something that does not exist.
Two features of the Spanish system surprise almost every foreign client.
Timescales are municipal, not national. There is no single national answer to "how long does a licence take", because the answer belongs to one town hall. A well-resourced municipality on the Costa Blanca may resolve a straightforward application in a few months. A busy coastal town hall in Andalusia or the Balearics, especially one dealing with a plot near the shore or in a protected setting, can take substantially longer. This is the dominant variable in any Spanish programme, and it is why we assess the specific municipality before committing to a date rather than after.
What you may build is set by the PGOU, and the land classification is decisive. The municipal planning instrument — the Plan General de Ordenación Urbana — classifies land and sets what can be done with it: buildable floor area, footprint, height, setbacks from boundaries, and often materials and roof form. The classification matters more than anything else in this section:
- Urban land with services in place is the straightforward case. The house is designed to the parameters the PGOU sets and the licence is a technical exercise.
- Land designated for future development may require the surrounding infrastructure to be completed, or a development instrument to be approved, before any individual house can be licensed. The plot is real; the permission is not yet.
- Rustic or non-developable land is the one that costs people money. Here the default is that a dwelling is not permitted. Where an exception exists it typically demands a separate prior authorisation from the regional authority, a minimum plot size that can be large, and a justification tied to the land's own use — and in some municipalities no new dwelling is possible at all.
A plot marketed as "suitable for building", or with a ruin on it, or with a neighbour who built ten years ago, is not evidence of anything. The only evidence is the classification and the parameters in the PGOU, read against the cadastral reference. We check that first, at no cost, because it is the cheapest possible moment to discover a problem.
The Technical Building Code and where a factory envelope wins
The Código Técnico de la Edificación is the national framework of performance requirements, organised into basic documents covering structural safety, fire safety, health and protection against damp, protection against noise, accessibility and energy performance. It applies in full to a modular house, and compliance is demonstrated in the stamped project that supports the licence.
Its energy section is the part where our method has a real rather than a rhetorical advantage. Spanish requirements for new dwellings are framed around limiting demand and consumption, with airtightness and the continuity of insulation doing much of the work. Both are produced far more reliably in a factory than on an open site: insulation is installed as a continuous designed layer instead of being cut around obstructions in the weather, junctions are repeatable, and the envelope can be tested before the house leaves the production hall. On a coastal plot with large glazing, the requirements that bite hardest are about solar control and summer performance rather than heat loss — deep overhangs, external shading, solar-control glazing, thermal mass and night ventilation, designed in rather than corrected later with an oversized air-conditioning unit.
The other basic documents shape the house in less visible ways: acoustic separation between rooms and against outside noise, damp protection that matters more on a coastal plot than an inland one, and fire safety requirements that affect routes and separations. None of these are optional extras, and all of them are settled in the project rather than on site.
Structure: Eurocodes, the Spanish annex and seismic zoning
Structural design follows the Eurocodes with the Spanish national annex, together with the national seismic norm and the national values for wind and snow. Three things reshape a design depending on where in Spain the plot is:
- Seismic acceleration. The seismic norm assigns a basic acceleration by municipality, and the south and south-east carry the highest values in the country — Granada, Almería, Murcia and stretches of the Alicante and Málaga coast among them. Where that value is significant it shapes the structural system itself and, in a modular house, the connections between modules and the fixings down to the foundation. It is designed in from the beginning; it cannot be added at the end.
- Wind, and the coast. Exposed coastal and island plots produce wind actions that inland plots do not, and they bring a corrosion environment with them. Fixings, frames, external metalwork and finishes are specified for that exposure rather than to a generic standard — a detail that separates a house that still looks new after ten years on the Costa del Sol from one that does not.
- Snow, inland and upland. Spain is not uniformly warm. Plots in the interior, in the Pyrenees, the Sierra Nevada or the central plateau carry real snow loads and cold-season demand, and the resulting envelope is closer to our northern European work than to a coastal villa.
The foundation is the part that cannot be manufactured in advance, and therefore the part most likely to move a budget. A geotechnical study is commissioned during feasibility, because the difference between competent ground and ground that needs deeper or reinforced foundations is a real number that belongs in the budget from the start rather than appearing once the excavator is on site.
Ten-year insurance under the LOE: the detail that surfaces at resale
If you read one section of this page, read this one — it is the Spanish equivalent of the question that decides projects in France, and it is just as consequential.
The Spanish Building Act, the Ley de Ordenación de la Edificación, sets three liability periods running from the completion of the works: ten years for defects affecting the structural safety of the building, three years for defects affecting habitability, and one year for defects in finishes. The ten-year structural risk is required to be covered by insurance.
Why it matters to you specifically: when you sell the house within ten years of completion, the notary will ask for that policy. Someone who has built their own house without it generally has to obtain an express waiver from the buyer in the deed — which is legally possible, but it weakens your position in the negotiation, unsettles buyers, and can trouble a buyer's mortgage lender at exactly the wrong moment. A beautifully built house can still be an awkward resale for this reason alone.
Alongside the insurance sits the Libro del Edificio, the building's documentation file: the as-built project, the certificates, the installation records and the maintenance instructions. It is not paperwork for its own sake — it is what a future buyer's lawyer will ask to see, and assembling it after the fact is far harder than compiling it as the work proceeds.
The coast: how close you can really build
Sea-front plots are why many clients come to Spain, and coastal law is the constraint most often misunderstood — sometimes sincerely, by vendors who have never had to test it.
Under the Coastal Act the shore itself is public domain and cannot be privately built on. Inland of it runs a protection easement — as a general rule a hundred metres, reduced to twenty in certain areas already developed when the regime came in — within which new residential construction is heavily restricted and requires authorisation from the regional authority. Beyond that lies a further influence zone with its own planning limits. Separately, and increasingly relevant, flood and coastal-risk mapping can constrain the finished floor level or the buildable footprint outright.
The important point for a buyer: these constraints attach to the land, not to the transaction. They are not negotiable, they do not depend on what the neighbours managed to build in 1985, and they survive a change of owner. On any plot near the shore this is the first thing we check and the last thing we would ever assume.
Transport and assembly without a border
This is the shortest section on any of our country pages, for a good reason. The modules are manufactured in our factory in Spain and travel by road to a Spanish plot. There is no customs clearance, no ferry or sea leg, no foreign transport authority and no import documentation.
- Special transport, domestically. Loads beyond the standard legal dimensions still need a special transport authorisation with an approved itinerary and escort vehicles where the size requires it — but it is one national regime, applied for by a team that applies for it routinely, rather than a sequence of foreign permissions.
- Module width remains a design decision. Wider modules mean fewer joints and better interiors against a more constrained route. That trade-off is settled during engineering against the real itinerary — including, on island projects in the Balearics, the port and the vessel.
- The last two hundred metres decide the job. Narrow urbanisation streets, steep coastal access, hairpin approaches, gateposts, overhead cables and the ground the crane must stand on typically matter far more than the motorway leg. We survey the final approach before the modules are sized, not after.
Assembly and craning take days rather than months, followed by joint sealing, service connections, external works and commissioning.
Taxes and what a non-resident buyer needs in place
Work on immovable property is taxed where the land is, so Spanish VAT applies to a house built in Spain. An execution-of-works contract for the construction of a dwelling can qualify for the reduced rate rather than the standard one where the legal conditions are met, and the way the contract is structured bears on that — which is a reason to settle it at the outset rather than discover it at invoicing. Around the construction sit the tax on the land purchase, the municipal tax on construction works and the licence fee itself, and then annual property tax and, for non-residents, the tax treatment of a second home. We set out the treatment we have assumed in the project breakdown so that your own Spanish adviser has something concrete to confirm; none of it is ours to advise on.
Practically, buying and building here as a non-resident requires a foreign tax identification number, a Spanish bank account, and a notarised deed for the land registered at the property registry. It also requires your own independent lawyer — not the vendor's — and usually a gestor for the administrative running. Everything on our side is handled in English while the licence application, the dealings with the town hall, the college-stamped project, the insurers and the local trades are handled in Spanish on your behalf.
What we handle, and what stays with you
One point of contact, in English, from the first look at the plot to the keys: verification of the land classification and buildable area against the PGOU from the cadastral reference; the geotechnical and hazard studies; bespoke architecture and the college-stamped technical project; structural design to the Eurocodes with the Spanish annex for the actual seismic, wind and snow values; CTE compliance including the energy calculation; the licencia de obra mayor filed and followed through at the town hall; coastal or regional authorisation where the plot needs it; the ten-year structural insurance route arranged rather than assumed; manufacturing in our own factory with scheduled reporting and a visit before the modules are closed up; special transport authorisation and escorts; assembly, connections and commissioning by our own teams; and handover with the first-occupation licence, the energy certificate and the Libro del Edificio complete.
What stays with you: the land purchase itself and your own legal and tax advice on it. We would rather work opposite a good independent Spanish lawyer than be asked to be one.

Frequently asked questions
Do I need a building licence for a modular house in Spain?
Yes. A new dwelling needs a licencia de obra mayor from the town hall of the municipality, granted on a full technical project signed by an architect and stamped by the professional college. Being factory-built changes nothing about this: Spanish law licenses the building, not the method used to assemble it. Timescales are municipal rather than national and vary widely — a straightforward municipality on the Costa Blanca may answer in a few months, while a busy coastal town hall in Andalusia or the Balearics can take considerably longer. We file the application and follow it through in Spanish on your behalf.
Can I legally build a modular home on rural land in Spain?
Sometimes, and this is the most common and most expensive misunderstanding among foreign buyers. What you may build is set by the municipal PGOU, which classifies the land. On urban land with services a house is normally straightforward. On rustic or non-developable land the position is restrictive — frequently requiring a separate prior authorisation, large minimum plot sizes and a justified link to the land, and in some municipalities no dwelling is permitted at all. A plot advertised as suitable for building is not evidence that it is. We check the classification and the buildable area from the cadastral reference before anyone commits to anything.
What is the Technical Building Code and does a modular house have to comply?
The Código Técnico de la Edificación is the national framework of performance requirements for structure, fire safety, health and damp, noise, accessibility and energy. It applies in full to a modular house exactly as it does to one built on site, and compliance is demonstrated in the stamped project supporting the licence. In practice the energy section is where a factory-built envelope performs best, because airtightness and the continuity of insulation are produced under controlled conditions rather than improvised in the open.
Is ten-year insurance compulsory when I build my own house in Spain?
The Building Act (LOE) sets three liability periods running from completion: ten years for defects affecting the structure, three years for habitability and one year for finishes. The ten-year structural risk is required to be covered by insurance, and it matters most at resale: if you sell within ten years the notary will ask for the policy, and a self-builder without it generally needs an express waiver from the buyer, which weakens the sale and can unsettle their lender. It is far cheaper to arrange the cover at the outset than to explain its absence later.
How close to the sea can I build in Spain?
Closer than you would like, and less freely than agents sometimes suggest. Under the Coastal Act the shore itself is public domain and cannot be privately built on, and inland of it runs a protection easement — as a general rule a hundred metres, reduced to twenty in certain already-developed areas — within which new residential building is heavily restricted and needs authorisation from the regional authority. Beyond that sits a further zone with its own limits. On a sea-front plot this is the first thing to verify and the last thing to assume, because the constraint attaches to the land regardless of what the vendor believes.
Does Spain have seismic design requirements?
In parts of it, yes. The national seismic norm assigns a basic acceleration by municipality, and the south and south-east — Granada, Almería, Murcia and stretches of the Alicante and Málaga coast — carry values high enough to shape the structural system and, in a modular house, the connections between modules and the fixings to the foundation. Elsewhere the governing actions are wind and, on higher ground, snow. The structure is calculated for the actual municipality rather than to a generic specification.
What VAT and taxes apply to building a house in Spain?
Construction work is taxed where the land is, so Spanish VAT applies. An execution-of-works contract for the construction of a dwelling can qualify for the reduced rate rather than the standard one where the legal conditions are met, and how your contract is structured affects this — so it is worth settling early rather than at invoicing. Around the construction sit the land purchase tax, the municipal tax on construction works and the licence fee, then annual property tax once the house exists. We state the treatment we have assumed in the project breakdown so your own Spanish adviser has something concrete to confirm.
What do I need in place as a non-resident buyer?
In practice a foreign tax identification number, a Spanish bank account, and a notarised deed for the land registered at the property registry. You will also want your own independent Spanish lawyer — not the vendor's, and not ours — to check the land's classification, charges and boundaries before purchase. We work alongside your lawyer and gestor rather than replacing them, and everything on our side is run in English.
How long does a luxury modular home in Spain take?
The manufacturing is the predictable part and the licence is not. Factory production runs in parallel with the licence and the foundations rather than after them, and craning and assembly on the plot take days rather than months. The variable that dominates the programme is how long your municipality takes to grant the licence, which is why we assess that before quoting a date. Spain is also the market with our shortest delivery leg: the modules never leave the country, so there is no customs clearance, no sea crossing and no foreign escort regime.
How much does a luxury modular home in Spain cost?
There is no catalogue price, because a bespoke house on an unseen plot cannot honestly be priced from a brochure. The budget is built on the project and broken down into architecture and engineering, manufacturing, transport, assembly, services and finishes, plus the licence and study costs, the insurance, the foundations and the utility connections. On Spanish plots the items that move most between sites are the foundations once the ground is known, the connections where services are not already at the boundary, and access for the crane.
