What are all the crucial and sometimes unknown steps involved in building a home from scratch in Spain?

The Local spoke with Pere Linares, CEO of House Habitat, a Barcelona-based company helping people to build eco-friendly and healthy homes across Catalonia and the Balearic Islands, to find out. 

  1. Buying your plot of land

The first step is to select and buy a plot of land. You will need to make sure there are no outstanding charges on the land.

Check with the municipality what the conditions are for building on that particular plot, different places apply different construction rules depending on whether the land is urbano, urbanizable or rústico

Once the land has been purchased you will need to go to your city or local council again to request the urban planning file.

This is a document that is valid for six months that allows your project to take place. It contains data on the area you can build on, as well as the general characteristics of the plot.

2. The Project

To start developing the project it will be necessary to have two things:

  • A geotechnical survey– showing the properties and characteristics can of the land so you can create the most suitable foundation.
  • A topographic survey– so you know the precise limitations of the terrain and its unevenness, which may need to be corrected.

Some municipalities also ask for a “As built” topographic survey, which you get once the work is finished.

You then need to find an architect and a construction company. These two parties will work together to create an executive project, including all the structural calculations and plans.  

If you find a construction company first, they may be able to help you find an architect who can bring your plans to life.

Once the basic project has been defined and accepted by you, the construction company and architect can start working out all the finer details for you to be able to get your licencia de obras or building permit.

For this, you will usually have to pay your architect 20 percent of the total fee.

3. Licencia de Obras

In order to start construction on your house, you will need a licencia de obras or building licence from the Urban Planning department of your corresponding city council, together with the basic project or executive project.

The process requires completing several administrative documents and paying the corresponding fees. These rates are dictated by each city council and are normally between three to four percent of the PEM (Presupuesto de Ejecución Material) or the budget you have for materials.  

On top of this, you will have to pay another two percent which is collected by each municipality for recycling and waste management during the project. This will be returned to you at the end of the building works.  

You may also need to pay more fees, which vary according to your city council, the plot and the type of project. This may be for things such as the planting of trees to replace the ones that you took out and can make your budget go up by around €10,000 or €12,000.  

Be aware that it can take anywhere from one month to 10 months in order to get your licence granted.

4. Building Process

Before starting on the construction of your house, you will need to assign a project management team, made up of your architect, the technical architect and the security coordinator (which can also be done by the technical architect). They will be in charge of everything from making sure the designs are carried out to checking the safety of the structure, quality control and carrying out calculations and measurements.  

They will also help organise certificates for banks, notaries, which are included as technical fees in your project.

It is also necessary to have a Plan de Seguridad (security plan). This can be organised by your construction company. Once approved by the technician, you can begin the Apertura del Centro de Trabajo (starting the work).  

You must also request and make payments for electricity and water connections so that your builders can perform their jobs correctly.  

Once the previous procedures have been carried out, the Acta de Replanteo document can be signed by all parties involved and work can begin. During the work process, weekly site visits will be made with all the technicians mentioned above, to define, check and plan all the work to be carried out. At each site visit, the surveyor will have to make a record of all the instructions for the day.  

5. The completion of your house 

Once the house is finished, the following documentation must be provided to your city council: 

  • Final Work Certificate: Document signed by the architect and technical architect, certifying that the work is finished.
  • Liquidation of Work: Document signed by the architect where the cost of execution of the work is certified.
  • End of Security Coordination: Document endorsed by the college of technical architects.
  • Quality control: During the course of the work, the technical architect must assess that all building materials are of high quality and are safe. 
  • Finalisation: Everything will be formally finalised and your house handed over to you once the final certified work certificate is available. This is a document which the city council and the notaries need to guarantee the completion of the work.
  • Building Book: Document detailing the definitive characteristics of the house, as well as its maintenance. This is drawn up by the architect. 
  • As Built Plans: These are the final plans, which agree with the work carried out. They serve as a guide to solve any potential issues down the line.

When all the previous documents have been delivered, you must register your property in the alta cadastral 902. Once completed, you can request your Licencia de Primera Ocupación (First Occupation License) from the city council. This guarantees that the house has been made according to the plans and is suitable to live in. To verify this, the they will conduct an inspection of your home and if they find everything is in order, will grant you a license. 

Once you have this licence, you can request the Cédula de habitabilidad or Certificate of habitability, where it is certified that the house meets the conditions of habitability established by law. This last document is used to request that services be connected to your house. It’s important to remember that the final NOTARIAL or REGISTRY certificate cannot be signed until the Licencia de Primera Ocupación, the Cédula de habitabilidad and the CEE label have all been granted.

What to do about insects and other pests in your home in Spain?

Bugs and insects can sometimes be a problem in Spanish homes, particularly during the summer months. Here's what to do if you get an infestation and how to prevent them from happening.

What to do about insects and other pests in your home in Spain?

Fruit flies buzzing around the bins, cockroaches in the kitchen and ants invading your food cupboards can be a common sight in your Spanish home, more often than not in summer.

But what can you do when insects invade your home? 

What types of pests are common in Spain?

Bugs and insects that commonly invade homes in Spain include fruit flies, ants, stink bugs, cockroaches, pantry moths, plaster bagworms and mosquitoes.

Those who have pets may also have a problem with your animals bringing fleas and ticks into the home too.

These can cause a nuisance, not only flying around your home and biting you (in the case of mosquitoes, fleas and ticks), but they can get into your food and lay eggs in your cupboards.

How can I get rid of bugs in my home?

One of the most important ways you can keep insects and other bugs out of your home is to eliminate food sources.

This means always doing the washing up as soon as you’ve finished eating so there are no scraps laying around, sweeping kitchens and dining rooms regularly and putting opened food items in the fridge instead of the cupboards.

You also need to make sure you regularly empty your rubbish bin and that there are no gaps between the lid and the bin that flies can get in through.

Dusting, hoovering and general regular cleaning will also keep other insects at bay such as plaster bagworms and moths that lay larvae on your walls and ceiling.

Those with pets should make sure that animals are treated with flea and tick protection and combed through with special flea combs to make sure bugs are not stuck in their fur.

Summer can of course be very hot in Spain, with temperatures regularly in the high 30°Cs or even low 40°Cs in some parts of Andalusia and other regions, meaning that windows and doors are often left open to ensure a breeze. Unfortunately, this means that your home is more accessible to insects too.

If you can, get a fly screen for your doors and windows, so you can leave them open, but no bugs can get in. These fine mesh screens can be bought from hardware or home stores such as Leroy Merlin and can simply be lifted into place when you need them.

If you can’t get screens installed, then consider planting certain plants on windowsills or balconies. Lavender, basil, lemongrass and mint are all natural insect repellents.

Electric fly swats, ant traps and sticky paper can also all help eliminate pests in your home.

When the situation becomes worse, simple everyday cleaning won’t suffice and you may need to use insecticides to kill the infestation. There are many different brands in Spain. Both Protect Home and Compo have several different products you can use.

If you don’t want to use chemical insecticides, natural ones made from white vinegar, citrus plants, or peppermint oil can also work.

Pest control

If the situation becomes completely out of control and you find that insects are not only entering your home but that they are breeding there too, it’s time to call in the professionals. Pest control services are available across Spain.

The first step is to check your home insurance to see if they will cover this service. If they won’t, they may be able to suggest a company that can help.

Otherwise, a quick Google search for ‘Control de plagas’ (pest control) and then your area should provide you with plenty of options.

According to the home website Habitissimo, pest control services in Spain can range from €80 up to €2,000 depending on the type of infestation you have, how serious the problem is and how big your property is. On average it will cost you around €267.
