" Description of development Construction of a new gable end roof to replace the existing roof, including the erection of two dormer windows and two front roof lights to create an additional self-contained flat in the roof space."
"An existing building is enlarged or extended and the enlargement or extension creates an additional dwelling. So, for example, a new qualifying flat built on top of an existing building would be within the Refund Scheme. But the conversion of a loft space into a flat would not."
"This is not a case where the roof space of a building used as [sic] by single household and occupied with the rest of the house was converted."
