New research from Barclays Mortgages reveals over half (57%) of British homeowners don’t know the size of their home and one in four don’t understand what a square foot is. However, one third consider property size more important than location in choosing their home, 38% wish they had moved into a bigger property and 37% plan on improving their homes in 2020 to create more space. In 2019 in England and Wales the average internal size of a detached property sold was 1,249 sqft, just under half the size of a standard tennis court, while the average terraced property is on par with the size of a badminton court (880 sq ft).
