There are various types and various forms of prefabricated houses, all of which can essentially be incorporated into four basic categories, all in any case in wood which are distinguished only by the type of the supporting structure. Recently the market has begun to show DIY houses with steel load-bearing structure, in these however there was no tendency towards the construction of prefabricated buildings of considerable size, but more than anything else DIY houses with considerable energy savings, in fact for their construction many technologically advanced materials were used in order to have do-it-yourself houses that were energy efficient and ecological.

To obtain the certification of an energy efficient and sustainable house, after assembly it must be checked by a third party who evaluates it based on the quality of the materials used for construction, and on the basis of the waste produced for the production of these materials.

Studies carried out at the Wageningen University in the Netherlands led to the European “passive house” project, which will serve as a model for a change towards sustainable and energy efficient building architecture. One of the most striking examples of a do-it-yourself home is the Energon in Ulm, Germany, a sort of futuristic house that presents innovative features such as triple-glazed windows that reduce heat exchanges with the outside, a covered atrium that facilitates ventilation in the apartment and the ingress of light from the windows. For example, heating in such a house is done by transferring heat directly from the floor so as to reduce losses due to energy transport. We have another example of a sustainable home from the 8000 sq m school in the wels region, which obtained the sustainable home certification after a significant renovation that led energy consumption to decrease from 165 kw / sq m to 15 Kw / sq m.

Other alternative models of sustainable DIY home are those produced in straw in Amsterdam, with wooden structure. These particular houses have are plastered in clay and have wall heating. It is possible to produce houses with zero energy costs, unfortunately the problem that arises is not so much planning or technological but unfortunately economic and mainly political. Only occasionally are there such advanced energy saving policies.

Unfortunately, in Italy the production and sale of do-it-yourself houses is not yet widespread so choosing the type of do-it-yourself house can be a great challenge. All in all, a person chooses the perfect house for himself by looking essentially at the aesthetic factor, this must not be misleading, in fact it is essential to know the whole offer or the company involved, the validity of all the documentation and instructions, and in last but not least the seriousness and professionalism of the people involved in the process. A useful thing to do may be to get in touch with people who have already done business with the company you want to do it with, so as to have real references of people who live or have lived in a prefabricated do-it-yourself house. . Finally, thanks to the prefabricated kits you can get the house of your dreams at reduced costs and times. Many people including those who are part of well-known manufacturers of prefabricated buildings recommend always and in any case to contact people and companies that already have considerable experience and expertise in this field in order to obtain short and long-term satisfaction with the building work from us request.
