This was followed by the West Midlands, which recorded an increase of 24.6% to £223.
At a local authority level, family homes in the district of Merthyr Tydfil in Wales have seen the biggest gains, with the price per sq ft now standing at £123, an increase of 38.2% in four years.
Looking at family homes with the most expensive price per sq ft, Kensington and Chelsea in London ranks in first place with a premium of £1,936 per sq ft.
Outside of London, Elmbridge in Surrey leads the way with an average price per sq ft of £591, an increase of £63 (11.9%) since 2016.
Gráinne Gilmore, head of research at Zoopla, said: “From our research, it’s clear that the price per sq ft of family homes varies hugely across the country.
“Although there has been an increase in the price per sq footage of properties in all regions of the UK, there are still pockets of the country with more affordable housing, while areas located in commuting distance from larger cities or near Areas of Outstanding Natural Beauty are likely to command a premium.”
