The sale of prefabricated houses skyrocketed with the pandemic and the reconsideration of our lifestyle for a much more independent, autonomous and far from the hustle and bustle of the city center.The shorter term, since they are built between 3 and 9 months, means that this type of modular housing is increasingly in demand.However, and as a consequence of this growing demand, prefabricated houses have evolved to the point of even being qualitatively equal to many of the traditional houses of all life.If we add the materials, dimensions or maintenance, among some other factors that we will mention in this article, the idea that prefabricated houses are cheaper may in the future remain a myth of the past.Although prefabricated houses in Spain represent only 1%, there is an increasing demand and this will translate into an increase in prices.Will we witness a new housing bubble?The range of prices for prefabricated houses is as wide as the variety of models that exist on the market.Even so, we could define a series of factors that directly influence the cost of a prefabricated house.To the housing costs you must add the cost of the land, that is, the price of the plot where you will locate your home.This may vary greatly depending on the area chosen.It does not cost the same to acquire a plot in Barcelona than to do it, for example, in Soria.One difference between prefabricated houses and conventional homes is that the former are generally suitable for being installed on undeveloped land.As with traditional houses, building a prefabricated house is associated with a whole series of permits: municipal licenses, deeds, construction taxes.Prefabricated houses are considered movable property (rather than real estate), that is, they could hypothetically be moved from one plot to another.This makes a big difference compared to its mode of financing since its owners will have to opt for private loans instead of mortgage loans, a banking product that usually has somewhat less advantageous conditions, which would end up increasing its final price.Another of the most determining factors when calculating the price of a prefabricated house is the choice of materials used in the house and its finishes.A prefabricated concrete house is not the same as a wooden one.In addition, the way the house is built, that is, if it is manufactured in advance or if it is built in-situ on the plot itself, will also greatly increase or decrease its price.prefabricated houses in Spain represent only 1%The more square meters, the higher the sale price.One of the main reasons that justifies the lower price of prefabricated houses is precisely their much smaller size than conventional constructions.Once you have your prefabricated house finished and ready to move into, you will have to take into account the possible maintenance costs that may be associated with it.Conservation costs are an item to consider in any type of home, but they take on a special role in prefabricated houses, especially if they are made of wood.Throughout the 20th century, futuristic experiences emerged, such as the Dymaxion house by Buckminster Fuller, originally from 1927, or the house of the future by Alison and Peter Smithson, in 1956. They were born from a new and optimistic vision of the way of living but perhaps somewhat disconnected from the tastes of the time.Today, according to different criteria, we can find several types of prefabricated houses on the market that adapt to any need.They are normally classified according to their construction materials and whether they are fixed or transportable.Concrete is one of the favorite materials for the construction of these houses.In most cases, a type of reinforced concrete is used that has a steel structure inside to offer more resistance.It has advantages such as acoustic insulation, but it is not as good in terms of thermal insulation.In terms of resistance, it is estimated that for 60 years it would not need repairs.Steel is another of the materials used in this type of house.Due to its ductility and lightness, it is a great option.The biggest drawback is its problem with heat conductivity, having to use thermal insulation to improve the energy efficiency of the house.However, the weight of the construction is reduced, lowering the cost of the foundation and its resistance to seismic tremors.Finally, we find the prefabricated wooden houses.Without a doubt, the best option to care for and respect the environment.Because it is a lighter material, foundation costs are also cheaper.It is not known if this will change in the future, but considering everything mentioned, it will surely be so.It is curious how the concepts are opposed to understand them, in the case of today, traditional versus prefabricated.But if we stop to think, that much-maligned element and symbol of the housing bubble, the brick, is still a prefabricated element.It is evident that what we understand now by prefabricated will be a standard, but hopefully we think about how we want to live, and the way we build is only a consequence.
