Buying a prefabricated house in Portugal: what you need to know

In recent years, prefabricated houses have become increasingly popular in Portugal – and it’s easy to see why. More affordable, sustainable and quicker to build, these homes are a great alternative to traditional construction, especially for international buyers looking to own property in Portugal.

Before you invest, it’s important to understand how prefabricated houses in Portugal work, what they cost, and the legal steps involved.

What is a prefabricated house?

A prefabricated house is built in a factory – either in modules or as a complete structure – and then transported to its final location, where it is assembled and finished. These homes can be made from wood, steel, concrete or other materials, and are usually quicker and more cost-efficient to build than conventional houses.

There is a wide range of prefabricated houses for sale in Portugal, from affordable starter homes to luxury modular villas with modern design and top-class technology. Whatever your style, the biggest advantages are faster construction times and lower costs compared with traditional building.

Choosing the right plot in Portugal

Before buying a prefabricated house in Portugal, you need a suitable plot of land. Not all plots are appropriate for this type of construction, so consider the following:

• Planning permission: check with the local câmara municipal (council) that the plot is classified as urban land and allows for a prefabricated home. Some areas have restrictions.
• Access to utilities: confirm whether the land has electricity, water, sewage and telecoms. If not, installing them could increase your costs.
• Topography and soil: a flat plot makes installation easier. Sloping land or unstable ground may require more complex (and expensive) foundations.

Licences and legal requirements

A common question is whether prefabricated houses in Portugal require planning permission. The answer depends on the type of home:

• Fixed prefabricated houses: if used as a permanent residence, they require the same permits as a traditional build.
• Mobile or modular homes: if the house is not permanently fixed to the ground, the rules can be more flexible – but always check with the council.

How much does a prefabricated house cost in Portugal?

The cost of prefabricated homes in Portugal varies depending on size, materials, design and finishes. On average, prices range between €30,000 and €150,000, although custom-designed projects can cost more.

Cheaper options are available if you choose simpler models or second-hand prefabricated houses. Despite the upfront investment, these homes generally have lower maintenance costs and higher energy efficiency, saving money in the long term.

Additional costs to consider include:

• Buying the plot of land
• Preparing the land and foundations
• Connecting to water, electricity and sewage
• Local council fees and licences
• Furnishing and interior decoration

Financing a prefabricated house in Portugal

Can you get a mortgage for a prefabricated house in Portugal? In some cases, yes. Several Portuguese banks offer mortgages for prefabricated homes, although terms vary:

• Fixed prefabricated houses: if the property is on legalised land and complies with urban planning rules, it may be financed like a traditional home.
• Mobile homes: if the house is not permanently fixed to the land, financing can be more difficult.

Sustainability and energy efficiency
