For example, would be built panels for prefabricated houses with an improved thermal insulation which is usually applied in the majority of the work. Prefabricated components would be built with the same quality materials that in the works or even superior quality, since the components and production process would be subject to greater control in the plant (environmental conditions, quality controls) in addition, the materials would be less exposed to inclement weather, since the mounting is carried out in a short period of time and they would not be exposed to inclement weather during months. They also possess greater strength to resist during transport and Assembly. For all these reasons would also more resilient after its construction. Prefabrication of constructive elements could pave the way towards the creation of buildings that were easier to disassemble or deconstruct when they reach the end of their useful life, so materials elsewhere. Greater control over the processes and materials, both in the management of waste generated (easiest upstairs at work) as in the Elimination of toxic products would also be possible. Other advantages that point would be that, in some cases, prefab houses could be completely disassembled and carried other chosen location, if residents so decided. With regard to aesthetics, the final result would not allow differentiate the prefabricated houses of those built on the ground.

It is believed that for many people it might be a way to get a House from which they currently call for design of more affordably. This is one of the key arguments that usually wields: some materials, saving time of execution and workmanship resulting in a cost savings. However, given the characteristics of the type of town planning and construction in our country, these advantages are reduced to some degree, because many of them are associated with prefab family house. Prefabricated houses are much more widespread in other countries whose urbanism is more diffuse, because its application in the urban environment: housing is more limited. But the theoretical environmental benefits of construction with prefabricated currently have defenders everywhere and deserve deeper reflection. Modular homes buy prefabricated house
