hen we talk about prefabricated and modular homes, it’s important to understand there are key differences between the two . Prefabricated homes are factory-built structures that are delivered directly to their intended location as a single unit. Modular homes, on the other hand, involve multiple pieces that are assembled on site .

Prefab houses come in a variety of designs, styles, and sizes. They can be tailored to the builder’s specifications or chosen from an array of pre-designed units offered by the manufacturer. Some larger prefabricated homes may be built in sections and then joined together at the building site. They also have certain advantages over more traditional building methods such as improved energy efficiency and increased offsite fabrication that speeds up construction time for builders.

Modular homes, on the other hand, consist of individual modules which are shipped onsite separately, usually by truck or rail depending on the size and scope of the project. The individual modules can then be connected together to form a complete house through special techniques like pinning and locking which allows for maximum flexibility when assembling them. Once completed, they look much like any other home from the outside but they tend to cost less than a completely custom-built home due to lower labour costs during assembly.

So, what is the difference between prefab and modular homes?

When comparing prefabricated and modular homes, one of the biggest distinctions is how quickly each type can be built as well as their transportability once completed:

  • Prefabricated houses take longer to construct than modular ones. Prefabricated homes must be fully fabricated at a factory before being shipped out.
  • Modular homes are constructed piece by piece at the building site.
  • Modular homes progress more quickly while still taking into account local regulations.
  • Shipping times vary significantly between prefabrication and modular homes.
  • Modular homes might need more time if cranes are needed for assembly.
  • Both types of housing often rank highly in energy efficiency ratings.
  • There is less variation among different models of prefab homes in terms of energy efficiency standards.
  • Modular homes might require additional insulation after assembly to achieve similar efficiency standards as prefab homes.

Permits and licences to build a prefabricated or modular house in Spain

The first step to building a prefabricated or modular home in Spain is obtaining the necessary permits and licences. Generally speaking, these permits can be divided into two categories: those required by local authorities and those required by central government. It is important to note that the specific requirements for permits may vary depending on the region in which you are building, so it is important to check with your local authorities for more information about the exact requirements.

  • Prefabricated houses take longer to construct than modular ones. Prefabricated homes must be fully fabricated at a factory before being shipped out.
  • Modular homes are constructed piece by piece at the building site.
  • Modular homes progress more quickly while still taking into account local regulations.
  • Shipping times vary significantly between prefabrication and modular homes.
  • Modular homes might need more time if cranes are needed for assembly.
  • Both types of housing often rank highly in energy efficiency ratings.
  • There is less variation among different models of prefab homes in terms of energy efficiency standards.
  • Modular homes might require additional insulation after assembly to achieve similar efficiency standards as prefab homes.
  • If you want to build a prefab house in Spain, it will be regulated by the same legislation as traditional constructions.
  • On what land can a prefabricated house be built? In order to build a modular home in Spain, it is necessary to do so on urban land. It is necessary to know the urban planning specifications of the plot and to have all the permits.
  • Site inspections and surveys. A series of site surveys and inspections must be carried out before building a house, including a topographical study (250-400€) and a geotechnical study (about 725€).
  • A building permit is not necessary for prefabricated houses, but planning permission is.
  • What taxes do I have to pay to build a prefabricated house? In order to start building, you must pay the Tax on Construction, Installations and Works (ICIO), VAT, Stamp Duty (Impuesto de Actos Jurídicos Documentados), and sometimes other taxes.
  • A prefabricated house in Spain must have a waste management and occupation of pavements guarantee, but it is optional to have ten-year insurance.
  • It is also needed a certificate of habitability is a document that proves a prefabricated house is suitable for residential use, and a licence of first occupation which proves that the construction of a building has been completed.

In conclusion, there is no one size fits all answer when asked which type of housing is better: prefabrication or modularity? Each has its own set of benefits depending on your needs or preferences so it’s best to weigh out your options carefully before making any decisions!
