British homeowners are converting dead space on their property to living space, according to a new survey.
An increasing number are carrying out attic, garage, cellar and shed conversions in order to provide extra space to live in.
Around one in five homeowners have undertaken conversions, with more than £90 billion having been spent on them, according to research by AA.
Nearly a third of these said that they had done so to increase the value of their home, in order to benefit financially from the buoyant property market, while giving them extra money to help purchase a new home.
Attics were the most popular conversion option, with the average costing £10,391.
It is thought that there was around £28 billion worth of possessions left in rooms that were previously unlived in.
Company spokeswoman Janet Pell said: "Many homeowners relish turning unused or ugly areas of their homes into liveable rooms as it means more space for family and less dusty boxes and clutter.
"But it is important that you ensure you have the appropriate building regulations approval before going ahead."
She also warned it was important that homeowners update their
home insurance cover following a conversion or extensions.
