The AMU data shows 23% of UK properties are now flats.
The research compiled by the Royal Mail’s Address Management Unit alongside the Centre for Economics and Business Research (CEBR).
London has the highest share, 54%, followed by Scotland 38%. The Northern Ireland currently has the lowest ratio, with just 11%.
Steve Rooney, head of Royal Mail’s Address Management Unit, reflects:
“While the distribution of property types has been relatively stable for the last four years, the number of flats has grown more than any other property type. This rise is most likely due to high land prices limiting the possibility of building semi-detached and detached houses. The number of multiple residency additions has increased steadily over the last nine months and we fully expect this trend to continue for the near future.”
