  • While architects' drawings aren’t always required to obtain planning permission, we highly recommend involving an architect for larger projects like loft conversions and home extensions. An architect will help create the best design solution based on your vision, producing detailed drawings and specifications that are essential for building regulations approval.

    With these drawings and material specifications in hand, Set Build Brighton Ltd can provide you with a comprehensive and fixed quote for your project, ensuring a smooth process from start to finish.

  • In most cases, a loft conversion is classified as permitted development, meaning you typically won’t need to apply for planning permission. However, certain limits and conditions must be met to ensure compliance. These include:

    1. Volume Limits: Your loft conversion should not exceed 40 cubic meters for terraced houses or 50 cubic meters for detached and semi-detached houses.

    2. Height Restrictions: The highest point of the new roof should not exceed the existing roof height, and any extension must be set back at least 20 cm from the edge of the roof.

    3. Materials: The materials used for the conversion should match the existing property to maintain aesthetic consistency.

    4. Windows: Any new windows must not overlook the properties behind yours, and if they are installed on the side elevation, they should be obscure-glazed and non-opening.

    5. Conservation Areas and Listed Buildings: If your property is located in a conservation area or is a listed building, you may need to apply for planning permission regardless of these conditions.

    At Set Build Brighton Ltd, we can help you navigate these regulations, ensuring your loft conversion meets all necessary guidelines. Our team will assess your property, provide expert advice, and assist with any planning applications if required, making the process as seamless as possible for you.

  • Building regulations set the minimum standards for construction work, ensuring that it is safe, structurally sound, and energy efficient. Almost all building projects—including alterations, extensions, and home improvements—must comply with these regulations. Adhering to building regulations is essential to ensure your project meets legal requirements and high-quality standards.
