When people ask how much it costs to build a house, they are usually thinking about construction costs. But construction is only one part, typically between 60% and 75%, of the total budget for a residential project in Spain. The rest is made up of expenses that rarely appear in the first quote and that can mean a difference of tens of thousands of euros between what the owner expected to spend and what they actually end up spending.<\/p>\n
This guide sets out every cost you need to allow for when building a house on the Costa del Sol, from the land to the new-build deed.<\/p>\n
The purchase price of the land is the most visible cost, but it is not the only one. When you buy a building plot on the Costa del Sol, you need to add:<\/p>\n
\u2022 ITP (property transfer tax) if the seller is a private individual: 7% of the purchase price in Andalusia.<\/p>\n
\u2022 VAT if the seller is a developer: 21% of the price (serviced land sold for the first time).<\/p>\n
\u2022 AJD (stamp duty) on the notarial deed: 1.2% in Andalusia (reduced to 0.1% for a main residence in certain cases).<\/p>\n
\u2022 Notary and Land Registry: \u20ac600\u20131,500 depending on the value of the plot.<\/p>\n
\u2022 Geotechnical survey: \u20ac1,500\u20133,000 (soil analysis, essential for designing the foundations).<\/p>\n
\u2022 Property valuation (if you are taking out a mortgage): \u20ac300\u2013600.<\/p>\n
Example: a plot bought from a private seller for \u20ac120,000 in Mijas carries additional acquisition costs of approximately \u20ac9,000\u201310,500 (ITP + notary + Land Registry + geotechnical survey).<\/p>\n
To build in Spain, the law requires a project signed by an architect and a professional site supervision team (direcci\u00f3n facultativa). These costs are fixed, not optional:<\/p>\n
\u2022 Basic architectural design (proyecto b\u00e1sico): needed to apply for the building permit. Typical cost: 1.5\u20133% of the PEM (Presupuesto de Ejecuci\u00f3n Material, the net construction cost).<\/p>\n
\u2022 Construction (execution) project: defines every construction detail and is needed to tender and contract the works. Cost: an additional 2\u20134% of the PEM (or 4\u20137% for the basic and construction projects together).<\/p>\n
\u2022 Building services design (electrical, plumbing, HVAC, telecommunications): 1\u20132% of the PEM.<\/p>\n
\u2022 Site management (architect): 2\u20134% of the PEM.<\/p>\n
\u2022 Construction supervision (building engineer \u2013 arquitecto t\u00e9cnico \/ aparejador): 1\u20133% of the PEM.<\/p>\n
\u2022 Health and safety coordinator: 0.5\u20131% of the PEM.<\/p>\n
In total, technical fees typically account for between 8% and 12% of the construction cost. On a project with a PEM of \u20ac300,000, that means between \u20ac24,000 and \u20ac36,000.<\/p>\n
In Klic Arquitectos\u2019 turnkey model, design and site management are handled by the same team under the same contract, which simplifies management and eliminates conflicts between phases.<\/p>\n
The cost of a major works building permit varies enormously from one Costa del Sol municipality to another. The most common charges are:<\/p>\n
\u2022 ICIO (construction, installations and works tax): 2\u20134% of the PEM depending on the municipality.<\/p>\n
\u2022 Municipal fees for issuing the permit: an additional 0.5\u20132% of the PEM.<\/p>\n
\u2022 Waste management guarantee deposit: 0.5\u20131% of the PEM (refunded once you prove that the rubble has been disposed of correctly).<\/p>\n
\u2022 Approval stamp (visado) from the College of Architects: \u20ac200\u2013600 per project.<\/p>\n
Marbella applies one of the highest ICIO rates on the Costa del Sol (up to 4%), while municipalities such as Mijas or V\u00e9lez-M\u00e1laga have somewhat more moderate rates. For a project with a PEM of \u20ac300,000, the ICIO in Marbella can amount to \u20ac12,000.<\/p>\n
If the plot does not already have utility connections in place (water, electricity, gas, sewerage, telecommunications), you need to budget for them. These costs vary enormously depending on the distance to the existing networks:<\/p>\n
\u2022 Mains water connection: \u20ac2,000\u20138,000 depending on distance and municipality.<\/p>\n
\u2022 Electricity connection (low voltage): \u20ac2,000\u20136,000. If a medium-voltage line and a private transformer substation are required: \u20ac15,000\u201340,000.<\/p>\n
\u2022 Sewerage connection: \u20ac3,000\u201310,000, or a septic tank that can be legalised if there is no mains network (\u20ac5,000\u201312,000).<\/p>\n
\u2022 Natural gas (if available in the area): \u20ac1,500\u20134,000.<\/p>\n
\u2022 Telecommunications (fibre): usually free of charge if the operator reaches the external connection point.<\/p>\n
Once construction is finished, there are still the legal formalities that allow you to live in and sell the house legally:<\/p>\n
\u2022 Certificate of Completion from the architect and building engineer: \u20ac500\u20131,500.<\/p>\n
\u2022 Energy performance certificate: \u20ac300\u2013600.<\/p>\n
\u2022 First occupancy licence (certificate of habitability): processed by the Town Hall, with fees of \u20ac300\u2013800 depending on the municipality.<\/p>\n
\u2022 Declaration of New Build deed (Escritura de Declaraci\u00f3n de Obra Nueva): notary \u20ac600\u20131,200, Land Registry \u20ac400\u2013800, plus AJD on the declared value of the construction.<\/p>\n
\u2022 Connecting utilities (contracts with the supply companies): \u20ac300\u2013600.<\/p>\n
For a 150 m\u00b2 mid-range house on the Costa del Sol (construction PEM: \u20ac240,000), the approximate total budget including all costs would be:<\/p>\n
\u2022 Construction cost (PEM): \u20ac240,000<\/p>\n
\u2022 Technical fees (~10%): \u20ac24,000<\/p>\n
\u2022 Permits and fees (~5%): \u20ac12,000<\/p>\n
\u2022 Utility connections: \u20ac8,000\u201320,000<\/p>\n
\u2022 Final legalisation: \u20ac3,000\u20135,000<\/p>\n
\u2022 Contingency (10%): \u20ac24,000<\/p>\n
\u2022 Approximate TOTAL: \u20ac311,000\u2013325,000 (excluding land)<\/p>\n
In other words, the real cost is between 30% and 40% higher than the initial construction budget. Understanding this before you start is the difference between a project that reaches the finish line and one that grinds to a halt halfway through for lack of funds.<\/p>\n
The ICIO (construction, installations and works tax) in Marbella is 4% of the PEM, one of the highest on the Costa del Sol. Some municipalities, such as Mijas or Torremolinos, apply rates of 2\u20133%.<\/p>\n
Yes. The Building Act (Ley de Ordenaci\u00f3n de la Edificaci\u00f3n, LOE) requires an architect to design and supervise any residential building work in Spain. Without a project signed by an architect, you cannot obtain a major works building permit.<\/p>\n
The PEM (Presupuesto de Ejecuci\u00f3n Material) is the cost of construction materials and labour, excluding the contractor\u2019s overheads, profit margin and VAT. Technical fees and permits are calculated on the basis of the PEM. The final price to the client (PEC, Precio de Ejecuci\u00f3n por Contrata, the contract price) is usually the PEM multiplied by 1.19\u20131.25 (overheads + profit), plus 10% VAT for a new home.<\/p>\n
If it is your main residence, Andalusia currently offers regional tax deductions for building or refurbishing a main residence (check the current framework with your tax adviser, as it changes with each annual budget). If the property is to be let, construction costs are depreciated for tax purposes over the useful life of the building.
