Why you should convert your loft

  • If you are considering expanding your property and wondering how best to utalize the space around you, a loft conversion could be the answer.
  • Building upwards can be one of the most cost-effective and straightforward ways of creating more space in the home. Small loft conversions and loft conversions on a larger scale are increasingly popular choices for homeowners looking to find extra living room without having to move home.
  • Whether the kids have returned from university or you are moving your parents in, a loft conversion can be the ideal fit whatever your plans.

VELUX Extension v Dormer

  • The most immediate thing to consider when planning for your loft conversion is ‘can I convert my loft?’ This is a sensible question to ask as not all roof structures can be converted. Different roofs require different work with some structures requiring planning permission while others do not. 
  • VELUX loft conversions, which sees one or multiple VELUX windows affixed to the roof in order to introduce light, are generally very cost-effective and do not normally need planning permission. Even the groundbreaking VELUX CABRIO balcony system does not require planning permission for homes not in conservation areas.
  • If you do not have enough head height in your loft, you may need to build a dormer, a small flat roofed extension with a window. This type of extension will typically cost a lot more money and require special loft conversion planning permission.
  • The Planning Portal can provide a full picture on the limits and conditions of your conversion and is where most planning permissions in England and Wales are now submitted through.
