A dormer loft conversion can cost on average anywhere between £20k to £60k depending on the size, design and materials. They are more expensive than just converting the loft space without a dormer because the work involves stripping off the roof and re-building the dormer.

Dormer loft conversions are much more spacious than a loft conversion without the dormer and they offer much better head height and usable space. Day light through windows or doors shed much more light and make the loft conversion feel like more of a standard room than a loft that’s been converted with velux windows. A full-sized dormer spanning the full width of your house can give you two thirds of the actual floor space on the ground floor, and quite often there is enough space for two bedrooms and a bathroom.

Depending on the area you live, one extra bedroom can add approximately £60k to the value of your house but this can increase, especially in the London areas where an extra bedroom can add up to £100k to the value of a property. The average Dormer loft conversion costs approximately £40k. Dormer Loft conversions are perfect for adding more space without the hassle of all the ground works and mostly the works are done from the scaffold, minimising the disturbance to the household occupiers until the stairs need to be installed. These days, most lofts fall under permitted development and do not even require planning permission.

The costs would normally include:

• Planning and Building regulations
• Scaffolding
• The construction of the dormer, including all external roof works
• Structural steel works
• New independent floor
• Stair case to loft
• Internal walls to form all rooms
• Windows or doors with Juliette balcony
• Electrics and plumbing
• Tiling and installation of new bathroom/en-suite
• Boarding and plastering
• Decorating
• Making good to 1st floor area disturbed for new stairs
