How much does a dormer loft conversion cost? It is a much-asked question by those keen to add extra space to their homes without extending outwards.

As with all types of loft conversion, the answer will vary depending on a number of factors, such as where in the country you live, how big you want the conversion to be, the current state of your loft and how you plan on using your newly-formed space.
