County Durham, Cannock Chase, Ceredigion and Bolsover are also among some of the best value areas for a semi, at just £16 per square foot.
Meanwhile in London, buyers can get more for their money by upgrading from a semi-detached home to a detached house.
Making that final move up the property ladder can provide better value per square foot for some homebuyers across England and Wales.
In Kensington and Chelsea, the average cost per square foot is £2,926 for a detached home, which is £1,172 cheaper than the average of £4,098 for a semi-detached house in the same borough.
Westminster, Hammersmith and Fulham, Hackney and Tower Hamlets are also more affordable for a detached home in comparison to a semi-detached property.
