The sector of prefabricated houses begins to settle in Spain

The sector of prefabricated houses begins to settle in Spain


MadridUpdated:

In countries like United Kingdom, Germany and, above all, in nordic, the Prefabricated houses are increasingly (worth the expression) settled, favored by one of its advantages, that of shorter construction time, in climates more extreme than ours. Also called industrial, they cover a wide range of solutions, from large installations of concrete or steel (steel framing), to wood or mobile, through those built from containers, either for single-family, residential, for offices, public buildings, etc.

As Javier Méndez, director of the Technical Office of the College of Quantity Surveyors of Madrid, is construction method it must be subject, of course, to regulations: "Except for constructions of little constructive nature and technical simplicity that do not have a residential or public character, the rest must satisfy the requirements of functionality, safety and habitability defined in the Law of building management . The technical code establishes the quality requirements that buildings must meet to meet the basic requirements. "

If we talk about security, aspects such as compliance with Royal Decree 1247/2008, of 18 July (Structural Concrete Instruction, EHE-08), to ensure that the design, execution and supervision of structures guarantee safety, are fundamental in the case of construction with concrete. And of grounding and lightning rod in the case of iron and steel, in addition to the regulation adjustment in the performance of "zero level" down.

Matter of time

In the case of Spain, it is located on the launching ramp: there is no second-hand market developed and they do not appear, at the moment, registered as such in the Property Registry (from this institution they indicate that they can register if they want those interested and , obligatorily, if they are bought with a mortgage). In any case, Guillermo Martínez, director of operations of Neoblock (Bauen group), highlights how their homes comply with the regulations: "Same as the conventional ones: Law of Building Regulation, technical code, municipal regulations, building license, etc.".

Martínez highlights the advantages of this type of construction (created in large part in a huge industrial warehouse): "This type of work, which is completed on site, involves considerable savings in indirect costs, travel, diets, overhead , etc., and complies with the protocols required in manufacturing, quality control, security … ». A process that, first of all, means a saving in time and greater possibilities of personalization. «A work -says Martinez- that would last 18 months we do it in eight, even less, with this modality, at an average price per square meter of 900-1200 euros, the higher the better the quality ".

More «eco»

Regarding sustainability, it is reaffirmed as one of the main advantages of this modality. In the opinion of Javier Méndez, who highlights how buildings should be increasingly faithful to the spirit "build to last": "One of the strategic objectives of the European route towards 2030 is to prevent and reduce the impacts of climate change, so the contribution that can affect the sector since the industrialization of the same is considerable. It will also make it possible to improve the efficiency of resources and the specialization of the workforce, in addition to supporting the circular economy in systems and materials that consume less natural resources and minimize the production of waste ". Less construction time, less impact on the ground.

Antonio Sánchez, manager of Custom Home, specializing in construction from sea containers, also underlines this commitment to efficiency and sustainability: "In traditional construction energy certifications are not achieved at a reasonable price, while constructions like ours start with a B certification (the first it is A) ». The recycling of containers to convert them into houses or buildings marks a lower contaminant footprint in a variable of this form of construction that, in cases such as England (with "Container City"), the Netherlands ("Keetwonen", a university complex with 1,000 apartments) or Sweden, have been consolidated as practical solutions for economically accessible housing that responds to the needs of labor mobility.

In the case of containers, in Custom Home they work from pieces of 20 and 40 feet "That, together, can oscillate between the 16 m2 -comments Sanchez- and the 7,600 of a building of six floors, at a cost of 575 euros / m2 on the ground floor and 650 euros on two or more heights". Another advantage is its anti-seismic reaction or to earth movements, as it would tilt, but would not break.

A habitability solution that, although it has not yet entered the circuit of the real estate agencies, has applications with travel, as underlined Ramón Riera, president of the association of real estate professionals Fiabci: «For example, in Barcelona there are 18 million free square meters for the so-called remounts, in cases in which the regulations granted greater construction in height, an aspect in which this type of buildings could be taken into account». And promoters the size of Aedas Homes already have six promotions and more than 100 homes of this type of construction in the Madrid's community. New times for a practical way to build.
