So that you can get a reasonable idea of the budget you would need to make allowance for, the following are approximate prices based on the average loft conversion projects carried out on properties in good condition in recent years. Please note that every single project is quoted individually, and prices vary according to size, condition of the property, cost of selected materials and so forth.

Example 1: Terraced property

Typically, this type of propery has two gable (vertical) sides and pitched (sloped) front and back roofs.

  • Option A: fit Velux roof windows to front and back roof slopes to create a new bedroom, accessed by new stairs positioned above the existing stairs. £20,500 + VAT
  • Option B: rear roof slope replaced with full length dormer, front roof slope fitted with two Velux roof windows. The dormer increases the usable loft space and head height to create a new bedroom (with possible en suite), accessed by new stairs positioned above the existing stairs. £22,500 + VAT
Example 2: Hip-ended semi-detached property

Typically, a two-hipped roof, with three sloping elevations (front, back and side), with the adjoining wall being a brick-built gable.

  • Option A: side roof slope fitted with access dormer (to accommodate new stairs). Front and back roof slopes fitted with Velux roof windows to create new bedroom with new stairs positioned above existing stairs. £24,500 + VAT
  • Option B: side roof slope rebuilt as gable end (vertical). Rear roof slope changed to full length flat roof dormer, front roof slope fitted with two Velux roof windows. the dormer and gable end increase loft space and head height to create new bedroom and en suite, with new stairs positioned above existing stairs. £32,000 + VAT
Example 3: Detached property

Typically, a four-hipped roof with all four sides pitched (sloping) towards the centre.

  • Option A: rear roof slope rebuilt as gable (vertical) end. Side roof slope to have flat roof dormer and Velux roof windows fitted to front roof slope. Gable end dormer increases loft space and head height to create two new bedrooms, with new staircase positioned close to main front door. £35,000 + VAT
