For those who aspire to maximum freedom, compositional and constructive, and have the patience and creativity necessary, the winning investment is to start from scratch and build your own home by choosing the place, the technology, the materials and the style. The expenses to be faced are of various types and it is complicated to predict them all. For those wishing to tackle the adventure of a new construction it is useful to try to calculate them.
Consider, for example, a detached house with a garden, on the first outskirts of a medium-sized town, with a gross floor area of ​​100 square meters. The main costs to be faced are: the purchase of land, the cost of construction including the profit of the manufacturer, charges and contributions to be paid to the municipality, technical costs, any interest payable for the mortgage.
The purchase of the land.
First of all it is necessary to buy a building land that allows the construction of the volume necessary for family needs. The cost varies greatly depending on the municipality, the position with respect to the center, the proximity to services and utilities, the availability of similar areas in the area and the panoramic view of the site. It usually accounts for about 20-30% of the finished value of the house and in our case, considering the real estate prices OMI, is estimated in: North - 600 € / m² Center - 650 € / m² South - 480 € / m².
Construction work.
The cost for the construction of the house depends in particular on the chosen construction technology, on the accessibility to the building site, on the quality of the finishes, on the number and type of technological systems to be installed, on the profit that the company wants to derive. Considering a standard quality for the example house we can assume the following values: North - € 1,200 / m² Center - € 1,300 / m² South - € 950 / m²
Contributions for the Municipality.
For the issue of the permit to build each Municipality requires the payment of the urbanization charges and a construction fee; these amounts vary from municipality to municipality and you can check them on the site of the institution. Indicatively we can consider for our count: North, Center, South - € 140 / m².
Technical expenses.
After having purchased the land it is also necessary to hire a qualified technician to draft the project to be presented to the Municipality and the Civil Engineers to obtain the necessary permits. The average cost of a project varies between 8% and 12% of the cost of the works and has a greater impact, due to fixed costs, on smaller buildings. For our example we take 10% for simplicity, obtaining: North - 120 € / m² Center - 130 € / m² South - 95 € / m².
Passive interests.
Finally, if to build your house you have to turn on a dumb, it is good to also consider the expenses for the interest expense that weigh on the value of the house finished for about 2-4%. We therefore consider the following values: North - 60 € / m² Center - 70 € / m² South - 50 € / m².
In summary summing all the main costs that we have analyzed a new detached house, about 100 gross square meters, built from scratch in the suburbs of a medium-sized Italian town will have a finite value between 1,700 and 2,300 euros per square meter. Specifically: North - € 2,100 / m² Center - € 2,300 / m² South - € 1,700 / m². These are indicative and wide-ranging values, useful to get an idea of ​​the costs for the construction from scratch of an independent house but can not replace either a precise estimate or a specific estimate.
