A loft conversion will make your home more valuable and sellable and if you can fit a bathroom or shower room up there, as well as a bedroom and built-in storage, you have the perfect master or guest suite.
Loft conversions cost from around £20,000, depending on the amount of work involved, the number of rooms created and the type of roof and conversion. The cheapest and easiest loft conversions are ones with skylights (eaves conversions), as the line of the roof is unchanged.
However, this isn’t ideal if the loft has limited space and head height. Building out the roof to create more useable space inside is often necessary, which means a more expensive and complicated dormer, mansard or hip-to-gable conversion.
