Make the Most of Your Loft Space

A loft conversion allows you to make the most of the space already available in your home. By converting your loft, you can create valuable extra space without extending into your garden or changing your home’s footprint.

With years of experience delivering loft conversions across East Sussex and West Sussex, our team works closely with you to design a space that suits your needs and complements your property.

Types of Loft Conversions

The right type of loft conversion will depend on your property, roof structure and how you plan to use the space. We will guide you through the most suitable option.

  • Velux Conversion - A cost-effective option that works within the existing roof structure. Velux windows bring in natural light, making the space feel bright and open without major structural changes.
  • Hip to Gable Conversion - Ideal for semi-detached and end-of-terrace homes. This type of loft conversion extends the roof to create additional internal space, often combined with a rear dormer.
  • Dormer Loft Conversion - One of the most popular choices. Dormers maximise available floor space and head height, making them perfect for creating large, functional rooms.
  • Pitched Roof Dormer Conversion - A more traditional design that blends with the existing roofline. This option is often suited to properties in conservation areas or homes where maintaining character is important.

Do I Need Planning Permission for a Loft Conversion in Sussex?

Many loft conversions fall under permitted development, meaning they may not require planning permission. However, this depends on the size and design of the project.

To qualify as permitted development:

  • Additional roof space must not exceed:
    • 40 cubic metres for terraced houses
    • 50 cubic metres for detached and semi-detached houses
  • The extension must not extend beyond the existing roof slope at the front of the property
  • Materials should be similar in appearance to the existing house
  • The highest part of the roof must not be exceeded
  • Verandas, balconies and raised platforms are not permitted
  • Side-facing windows must be obscure glazed and positioned above 1.7 metres
  • Roof extensions should be set back from the eaves where possible

Other considerations may include previous building work, structural calculations and protected species such as bats.

We will guide you through the planning process and advise whether your loft conversion requires planning permission or falls under permitted development.

*Information based on Planning Portal guidance. Requirements may vary depending on your property and local authority.
