Full Range of Loft Conversion Services

We offer a wide range of dormer loft conversions to suit all property styles and requirements:

  • Rear Dormer

    Extends your roof to create extra head height and floor space, typically with vertical walls and a flat roof.
  • Side Dormer

    Similar to a rear dormer but built on the side of your property; detached homes may even allow for two.
  • L-Shape Dormer

    Adds significant space with an additional back extension, ideal for Victorian and Edwardian homes.
  • Hip-to-Gable Conversion

    Perfect for semi-detached houses, extending the sloping side of the roof vertically to maximise internal space.
  • Velux Conversion

    The most cost-effective option, using roof windows to bring natural light into your loft without altering the roofline.
  • Mansard Conversion

    Creates maximum floor space with a steeper roof angle, often giving your home the feel of a new storey.

We also cover full roof conversions, bungalow roof conversions, and roof light conversions. No matter the layout of your home, we’ll guide you through the best solution to meet your needs.
