Grosso, between Ciriè and the mouth of the Lanzo valleys

Grosso is a small municipality in the metropolitan city of Turin, on the upper plain north of Ciriè, where the countryside starts to rise towards the mouth of the Valli di Lanzo. It stands at around 400 metres, with a compact centre and neighbourhoods of detached houses built in recent decades among meadows and fields.

It is mainly a residential village. Ciriè, with its hospital, secondary schools and shops, is close, and Turin and Caselle airport are within driving distance for those who work in the city. The market offers detached houses, homes with gardens and a few old rural houses to renovate; for a house from the 1970s or 1980s, insulation, the boiler and the windows matter a great deal, since they decide the energy rating and the cost of every winter. The climate zone is E.

In 2023 there were 990 residents, down 4.8% on the 1,040 of 2011. The average age (47.5) is in line with the metropolitan city (47.4), over-65s make up 26.1% and foreign residents 4.4%. Declared incomes are close to the provincial average, just below it. Households have 2.27 members on average.

The municipality is in seismic zone 3, like 271 of 312 municipalities, with a low expected ground acceleration of 0.060 g. If you are buying a detached house, look instead at whether extensions, canopies and basement rooms have the proper permits.

The report uses Revenue Agency (Agenzia delle Entrate) maps to go from the address to the plot, and there it shows the official flood maps along streams and canals, the local price band and the distance to services.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.060 g, a moderate value: the level with a 10% probability of being exceeded in 50 years, on rock.

Even in zone 3, seismic standards apply to new buildings: for an older building, ask about the design year and any structural work.
