The calculation of the sales area, also known as “superficie commerciale” in Italy, plays a key role in the valuation and marketing of properties. This method of calculation forms a basis for comparative values and includes not only the pure living space with interior and exterior walls, but also the proportionate areas of balconies, terraces, cellars and other ancillary rooms. But what exactly is the “superficie commerciale” and how is it calculated?
Retail space for real estate in Italy
Do you often come across the terms retail space or commercial space in real estate advertisements and wonder what exactly they mean? In this guide, we explain what they mean and how they are calculated.
The sales area in Italy is calculated according to regulated standards, including UNI 10750 and D.P.R. 138/1998, and is essentially made up as follows:
- Interior | The entire living area, including interior and exterior walls, is fully included in the sales area. However, external walls are only taken into account up to a certain width, while only half of common partition walls are included in the calculation.
- Ancillary areas | Balconies, loggias, terraces, verandas, gardens, cellars, parking spaces, garages and similar ancillary areas are included in the sales area on a pro rata basis, but at a reduced percentage. The exact calculation may vary depending on the area: Basement areas are usually calculated at 20% to 35%, balcony and terrace areas between 25% and 50%, garden areas between 10% and 15%, car parking spaces between 20% and 40% and garages at around 50% of the area.
Valuation factors and their significance for the property value
In addition to the valuation of pure retail space, many other factors are also decisive in real estate valuation. These often lead to significant differences in the price per square meter of different properties. A property should therefore never be reduced to its retail space alone. Rather, a comprehensive valuation also takes into account the specific qualities and special features of the property and thus enables a more precise assessment that goes beyond the mere number of square meters.
CONCLUSION
Knowledge of Italian retail space calculation is essential for anyone looking to invest in the Italian real estate market. The combination of living space and the additionally calculated ancillary areas means that the sales area provides a comprehensive measure of value based on objective guidelines.
