A loft conversion or having an extension built are two of the most effective ways to boost the value of a property, a survey has suggested.
Properties with somewhere to park are worth more
On average, an extension adds 12% and a loft conversion 10.9% to a property's value, the Nationwide Building Society survey found.
Adding a garage or extra bedroom boosts value by 8% and 5% respectively.
But the group added that regardless of work done to a property, location was key to its price on the open market.
"A house in the best neighbourhood can command a price more than a third higher than a similar house in an average area," said Fionnuala Earley, Nationwide group economist.
Nationwide identified other factors that can detract from a property's value.
It said property without central heating could reduce the price of a home by nearly 7%.
And having no garage or drive can knock about 6% off a property's asking price.
