Types of Loft Conversions we offer in Blackfen

  • Dormer Loft Conversion

    A Dormer loft conversion creates extra space by adding a vertical extension to a sloped roof. This type of loft conversion maximises headroom and allows for windows, making the attic more suitable for bedrooms or other living spaces. It’s a great way to expand a home without major construction.

  • Mansard Loft Conversion

    Mansard loft conversions maximise available roof space by altering the rear slope into a near-vertical design. This type of conversion adds substantial headroom and space, making it ideal for adding new bedrooms, living spaces, or an office, and significantly boosting the home’s functionality and value.

  • Hip-to-Gable Loft Conversion

    A Hip-to-Gable loft conversion involves extending the “hipped” side of a roof to form a vertical gable wall, maximising internal space. It’s a popular choice for end-of-terrace or semi-detached homes, providing more headroom and making the loft suitable for extra bedrooms or living areas.

  • L-Shaped Loft Conversion

    An L-shaped loft conversion involves creating two connecting dormer structures, typically at the rear of the property, forming an “L” shape. This conversion provides significant additional space, ideal for creating multiple rooms or a spacious master suite, and works best for Victorian or Edwardian terraced houses.

  • Rooflight Loft Conversion

    A Rooflight loft conversion involves converting the existing loft space without altering the roof’s structure. Instead, windows are added to the roof for natural light. It’s the least invasive and most cost-effective loft conversion, ideal for maximising space with minimal changes, maintaining the property’s original appearance.
