Permitted Development - Hip to Gable Loft Conversion 2023

A hip to gable loft conversion is a popular way to add extra living space to your home without the need for planning permission. This type of conversion involves altering the sloping side of a house, called the hip, and turning it into a vertical gable end. This provides additional space for a bedroom or bathroom, and can also improve the overall appearance of the property.

One of the main advantages of a hip to gable loft conversion is that it falls under permitted development rights, which means that planning permission is not required as long as certain criteria are met. These include:

  • The property must be a detached or semi-detached house, and not a flat or maisonette.

  • The conversion must not exceed the highest part of the existing roof.

  • The conversion must not extend beyond the plane of the existing roof slope of the principal elevation that fronts the highway.

  • The conversion must not include the addition of a veranda, balcony or raised platform.

It is important to note that even if your property meets these criteria, it's always best to check with us or your local council to confirm that a hip to gable loft conversion is permitted under permitted development rights. This is because certain areas may have additional restrictions or conditions that need to be met.

Another important aspect to consider is the structural integrity of your property. A hip to gable loft conversion can be a complex and involved process, and it's important to ensure that the structure of your property can support the additional weight of the conversion. A professional builder or architect can advise you on this.

In terms of cost, a hip to gable loft conversion can vary depending on the size and complexity of the project. However, it is generally more affordable than a traditional loft conversion as it does not require planning permission.

In conclusion, a hip to gable loft conversion is a great way to add extra living space to your home without the need for planning permission. It's important to ensure that your property meets the criteria for permitted development rights and that the structural integrity of your property can support the additional weight. A professional builder or architect can advise you on this and also provide a cost estimate for the project.
