This positive trend was not limited to any one region of the country. In fact, the number of new homes registered to be built in 2021 increased in every region except London, with the North East, East Midlands, and Eastern regions experiencing growth rates of over 45 percent.


One of the most significant growth areas within the Italian construction industry has been infrastructure construction, which has seen a marked increase in market share. This trend is expected to continue, as the government has committed to investing heavily in infrastructure development across the country in the coming years.
