Authentic modular homes based on used shipping containers that allow a second life as prefabricated houses.When we talk about prefabricated houses, all kinds of modular homes come to mind, normally built with materials such as concrete or wood, but what many did not imagine is that they could also be made with used shipping containers that have transported goods.Well, like most of the time, reality is stranger than fiction.In addition, the construction of this type of revolutionary designs have a Spanish seal and a price starting at 14,600 euros.According to sources contracted by this means with the company itself, the average cost is 950 euros per square meter of housing, so in any case the final budget would have to be calculated based on the size you wish to acquire.Transportation is not included, so it must be calculated separately in the budget.The company responsible for giving this type of mobile home a second life is the Murcia-based company Roscontainer, which allows you to rent and buy these warehouses, taking advantage of industrial elements that are easy to assemble in a very short period of time.But the thing does not end there, because these modules can even be used as offices, gyms or even to add it to your usual home and thus create an extra space in the form of a cellar, a place of study or a very particular beach bar.As far as size is concerned, several options are available ranging from 20 to 40 square meters.As for delivery times, they range from a week to 15 days, depending on where the potential buyer wants to install it.In addition, it should be noted that there is a significant cost difference between a new container and a used one, more than half the price.The first thing to know is that among the requirements to live in a prefabricated house with maritime containers, it is necessary to own land.In addition, the plot must be developable.Also, you have to draw up a construction project, obtain the appropriate licenses for construction and pay the corresponding fees at the town hall.In addition, once the fit and volume of the house on the plot has been planned by an architect, a project of the work to be carried out must be drawn up.On the other hand, it should be noted that in Spain a distinction is made between real estate that is "land, buildings, roads and constructions of all kinds attached to the ground".On the contrary, those that "can be transported from one place to another without detriment to the immovable thing to which they were attached" are established as movable property.Normally, shipping containers would be considered movable property, as they can be easily transported.The reason is none other than because they do not have foundations or other types of anchorage to water or electricity supplies, they are considered self-sufficient and have their own supplies.A building license is not required, but it is advisable to consult the town hall because in some specific cases there are already regulations in this regard.This is the case of the Land Law of the Community of Madrid, which establishes the Urban Discipline Regulation, which includes the consequences of installing a mobile home without a license on urban land.Otherwise, an administrative file for the restoration of legality could be opened and the acts of building or land use will be suspended.Of course, unlike real estate, they do not need to be registered in the property registry, which means not having to go through the notary and make the corresponding payment.
