The most common question from anyone considering a prefab home in Spain is always the same: how much does it cost? The honest answer is that it depends heavily on what the quoted price actually includes, the construction system, the size, and the finish level. This guide breaks down the real 2025 Spanish market ranges so you can compare quotes with confidence.
A 120 m² turnkey prefab home in Spain costs between €130,000 and €280,000, depending on the construction system and manufacturer — excluding land, foundation, and permits.
The 5 price segments
Homes up to 90 m² sold as structure-only or advanced self-build. Prefab concrete or modular steel. Basic finishes.
- Examples: Grupo Eurocasa Classic 90, Maestro Casas Eco 70
- Usually excludes: foundation, exterior installations, kitchen furniture
- Suited to: buyers with a serviced plot, experienced self-builders
Turnkey homes of 80–130 m². Timber or concrete. Equipped kitchen, double-glazed windows, standard finishes.
- Examples: InHaus S-80, InHaus M-120, Hormipresa H-100
- Usually includes: structure, envelope, installations, kitchen
- Suited to: first-time buyers, couples, small families
Turnkey homes of 100–180 m². Timber, CLT, or hybrid systems. Medium-to-high quality finishes, energy rating A or A+.

Bespoke projects, large footprints (250+ m²), or manufacturers with a strong architect-led design component.

- Includes: architect, turnkey project, certified materials
- Suited to: luxury second homes or primary residences with no budget ceiling
How prices vary by region
The advertised factory price of a prefab home is fairly consistent nationwide, but the total cost of getting a house built varies significantly by region — mostly because of land prices and transport distance from the factory.
- Madrid and surrounding provinces — Land is the dominant cost driver, often exceeding the price of the house itself within 40 km of the capital. Manufacturers with a Madrid-area presence, such as Atlántida Homes, reduce transport costs for buyers in the region.
- Valencia, Alicante, and Castellón — One of the most cost-effective regions thanks to InHaus's factory being based in Valencia. Inland plots in these three provinces remain some of the most affordable developable land in the country. See our dedicated guide to prefab homes in Valencia.
- Cataluña and the Basque Country — Home to most of Spain's CLT manufacturers (Arquima, Noem, Ubiko, Egoin), which pushes the regional average toward the premium segment. Land prices near Barcelona and Bilbao are also above the national average.
- Andalucía and Murcia — Land is typically cheaper than the coastal average, and concrete systems dominate due to their thermal performance in a hot climate, keeping total project costs closer to the lower end of the standard segment.
- Northern Spain (Galicia, Asturias, Cantabria) — Timber systems are more common given the wetter, cooler climate, and land prices outside the main cities remain relatively low.
Transport is typically charged per kilometre beyond a manufacturer's standard delivery radius (often 200–400 km from the factory). Choosing a manufacturer close to your plot can save €3,000–€10,000 on a mid-size project — sometimes more than the price difference between two competing quotes.
How financing affects your effective price
The quoted price of a prefab home is only part of the equation — how you finance it changes the real cost. Most Spanish buyers use a self-build mortgage ("hipoteca autopromotor"), which releases funds in stages tied to construction milestones rather than as a single lump sum at signature.
- Loan-to-value: Spanish banks typically finance up to 80% of the appraised value of land plus construction, meaning buyers need 20–30% in own funds.
- Staged disbursement: funds are released against certified progress (contract signature, factory completion, on-site assembly, final handover), which affects cash-flow planning during the build.
- Interest rate impact: a variance of even 0.5 percentage points on a €200,000 self-build mortgage can add or save several thousand euros over a 20–25 year term — worth shopping around for.
- Bridge financing: buyers who already own a home sometimes use bridge mortgages to fund the self-build while their current property is on the market.

Comparison table by construction system
The construction system is the single biggest driver of final price per square metre. If you're weighing timber options, see our timber frame vs CLT comparison.
| System | Average price €/m² (turnkey) | Main advantage | Best for |
|---|---|---|---|
| Prefab concrete | €1,000 – €1,500/m² | Lowest price, durability | First home, continental climate |
| Modular steel | €1,200 – €1,800/m² | Fast assembly | Extensions, second homes |
| Timber (timber frame) | €1,300 – €2,000/m² | Thermal efficiency, comfort | Atlantic climate, northern Spain |
| CLT (solid timber) | €1,800 – €2,800/m² | Carbon footprint, strength | Premium, high-demand zones |
| Hybrid | €1,500 – €2,400/m² | Design flexibility | Bespoke projects |
What the advertised price almost never includes
The price you see in a manufacturer's catalogue is rarely the total cost of your home. These extra costs can add 30–60% on top of the advertised price:
- Land: varies enormously by location (€20,000 to €300,000+ in high-demand areas)
- Foundation: €10,000 – €30,000 depending on soil type and footprint
- Architect and technical project fees: €5,000 – €20,000
- Building permit: €1,000 – €8,000 depending on the municipality
- Utility connections: water, electricity, gas, sewage — €8,000 – €20,000
- Exterior works: fencing, access, garden — €10,000 – €40,000
- VAT: 10% for a new-build primary residence
- Notary, land registry, admin fees: €2,000 – €5,000
A €150,000 "turnkey" quote can become €230,000–€260,000 once land, foundation, connections, permits, and VAT are added. Always ask for a detailed line-item breakdown of what's included.
What drives the price up most
Beyond the construction system, these elements have the biggest impact on final budget:
- Floor area: each additional square metre has a marginal cost that lowers the average price per m²
- Number of storeys: a second floor costs more than the first due to slabs and stairs
- Roof type: pitched or complex roofs cost more than flat roofs
- Level of customisation: closed catalogue models are cheaper than fully bespoke projects
- Energy certification: Passivhaus adds 10–20% to the base cost
- Transport distance: some manufacturers charge a premium for sites outside their usual delivery radius. In regions with strong local coverage such as Valencia, prioritise manufacturers with regional experience.
- Home automation: integrated systems can add €10,000 – €30,000
How delivery timeline affects total cost
Faster isn't always cheaper, and slower isn't always a red flag — but timeline does interact with your total budget in ways worth planning for:
- Rent or temporary housing during the build: if you're selling your current home before the new one is ready, a 4-month concrete build versus a 12-month bespoke CLT project can mean the difference between a few months and a year of parallel housing costs.
- Interest accrual during construction: a self-build mortgage typically accrues interest on drawn amounts from the moment each tranche is released, so a longer build extends the period before you're paying a normal amortising mortgage on the full amount.
- Material and labour cost inflation: fixed-price contracts protect you from this, but not every manufacturer offers one — confirm in writing whether your quote is fixed for the full project duration or subject to revision.
- Faster delivery, less customisation: the manufacturers with the shortest timelines (2.5–4 months) typically achieve this through standardised catalogue models with limited layout changes — a trade-off worth weighing against a fully bespoke design.
How to compare quotes correctly
Comparing prices across manufacturers is difficult unless you start from the same baseline. Ask every manufacturer these questions:
- Does the price include the foundation? Transport and assembly?
- Is the price for "dry structure" or "turnkey"?
- What quality of exterior joinery (windows, doors) is included?
- Does it include electrical, plumbing, and HVAC installation?
- What energy certification does the model have?
- What does transport to my plot cost?
- What is the delivery timeline from contract signature?
Always request quotes for the same model and the same specification. A generic "per m²" quote doesn't let you compare properly. Insist on a line-by-line breakdown.
