What does it cost to build a house in Spain?

The price of a new build in Spain depends on far more than the price per square metre a builder quotes. These are the items to plan for, why the numbers vary so much – and how to make a budget that holds.

The price per square metre is only the start

When people say it costs so much per square metre to build in Spain, they nearly always mean the construction itself: structure, roof, windows, services and interior finishes. Architect, taxes, utility connections, site work, pool, landscaping and furniture come on top.

Construction cost varies with region, finish, plot and how busy the market is. The coasts of Andalusia, the Valencia region and the Balearics are usually more expensive than inland areas. A sloping plot with rock in the ground can add tens of thousands of euros in groundwork and retaining walls on its own.

Use prices per square metre to compare quotes, not as a budget. A budget has to be built item by item.

The items to plan for

A realistic budget for a new house in Spain typically has these main items:

  • Plot, with title deed (escritura) and registration – plus the purchase tax, which depends on whether you buy from a private seller or a developer
  • Architect and design: the project for the permit (proyecto básico) and the construction drawings (proyecto de ejecución) – the latter always needs approval (visado) by the college of architects
  • Site supervision: the architect (dirección de obra) and the building engineer (dirección de ejecución), plus a health and safety coordinator
  • Geotechnical report (estudio geotécnico) and a survey (topografía) where needed
  • Municipal charges: the construction tax ICIO and the fee for the licencia de obra
  • Construction: groundwork, concrete and masonry, roof, windows and doors, plumbing, electrics, ventilation, kitchen, bathrooms and finishes
  • Water, power and drainage connections (acometidas) – expensive if the networks are far away
  • Outdoor areas: terraces, pool, fences, planting and driveway
  • Completion: completion certificate, occupancy permit, notary and registering the new building (declaración de obra nueva)
  • Insurance (construction all-risk and the ten-year seguro decenal, compulsory except for self-builders building a home for their own use) and a contingency for the unexpected

Taxes and fees that often surprise

ICIO (impuesto sobre construcciones, instalaciones y obras) is a municipal tax charged on the net construction budget (presupuesto de ejecución material – without fees, the builder's overheads and VAT). The rate is set by each town hall, with a legal maximum of 4 % – check the rate in your municipality before you apply.

VAT (IVA) on building a home is normally lower than the standard rate, but which parts of the work qualify depends on the contract. Ask builders to quote with and without IVA, and ask your lawyer (abogado) or adviser which rate applies.

Once the house is finished, the new building has to be declared before a notary and recorded at the land registry. That triggers a stamp duty (AJD) that varies between regions, plus notary and registry fees.

Why the numbers vary so much

Two quotes for the same house can differ by 30–40 per cent without either being unreasonable. Usually it is about scope: one builder includes kitchen and bathrooms, another only the shell; one has priced rock in the ground, another has made a reservation.

So always compare item by item, and ask everyone to price the same documents – the same drawings, the same description and the same questions answered. A tender package in which everyone gets exactly the same makes the quotes comparable.

How to make a budget that holds

A good build budget keeps three numbers for each item: the estimate, the actual (agreed or invoiced) cost and what has been paid. You then see early if the project is heading over budget, and how much cash you will need in the coming months.

  • Enter every item from the list above – including the ones that will surely be small
  • Set aside a contingency for the unexpected, especially for groundwork
  • Record every payment with its date and currency; if you pay from another currency, lock the rate on the day you pay
  • Update the estimate when quotes arrive and the actual cost when you sign
  • Follow the payment schedule in the building contract (often by progress, so-called certificaciones)

A rough estimate from the drawings

If you have the architect's drawings, MinePlaner can read them floor by floor, find rooms and areas and make a rough estimate per package – groundwork, structure, roof, windows, electrics and plumbing, kitchen and bathrooms – with local prices including labour. It is a starting point for checking quotes, not a quote.

Frequently asked questions

What does it cost to build a 150 m² house in Spain?

It depends on region, plot and finish. Build the budget item by item: construction, architect and supervision, ICIO and fees, connections, outdoor areas, notary and registry – and a contingency. Prices per square metre are for comparing quotes, not for budgeting.

What is ICIO?

ICIO is a municipal tax on building work, charged as a percentage of the building budget. The rate is set by the town hall and paid in connection with the building permit.

Is the architect included in the build price?

Almost never. Architect, design and supervision are separate contracts. Ask whether the fee covers the permit project, construction drawings, visado and site supervision.

How big a contingency should I have?

There is no single answer, but many people plan 10–15 per cent of the construction cost – more if the plot is difficult or the design is not finished.
