5 Things You Need to Know Before Doing a Hip-to-Gable Loft Conversion

A loft conversion is one of the most popular and affordable options if you want to make the most of the space available in your home. It’s often easier and more convenient compared to building an extension on the home and doesn’t mean that you lose out on garden space either. If your home has a hip roof, then you might lack the head height to get the loft conversion that you want. In this case, a hip to gable loft conversion might be worth considering. 

What is a Hip to Gable Loft Conversion?

A hip-to-gable loft conversion is a good option to consider if you have a hipped roof that shrinks the usable floor area. While a certain amount of leeway with loft stairs is permitted by Building Regulations, it’s still important to ensure that there is clear headroom of 1.9m above the middle of the stairs to ensure that people can enter the loft room safely. A hip to gable loft conversion maximises the interior space that is available, by replacing the hipped roof section with a standard gabled roof. To do this, the existing end wall is built up to form a new gable, and the space where the roof hip used to be is enclosed. 

The Difference Between a Hip and Gable Roof

The main difference between a hip and a gable roof is the shape of the structure. 

What is a Hip Roof?

A hip roof has four distinct slants, each of which is the same length. They are joined together to create a rooftop that is square. 

What is a Gable Roof?

A gable roof consists of two sloping sides. The stops are usually rectangular, but this can vary depending on the overall design of the roof and the property. 

Advantages and Disadvantages of a Hip to Gable Loft Conversion

If you are considering getting a hip-to-gable loft conversion, there are some pros and cons to consider before you decide if it is the right choice for you. These are:


  • Can be done under permitted development
  • Easily blends in with the existing property for an aesthetically pleasing result
  • Suitable for chalets and bungalows
  • Can be combined with a rear dormer loft for even more space


  • Does not add a huge amount of space without a dormer extension
  • Not suitable for mid-terraced properties as there are no gable ends
  • Can leave the roofscape looking imbalanced

Planning Permission

Like other types of loft conversion, hip to gable loft conversions do come under permitted development, so you don’t need traditional planning permission to have one done. However, you will need to ensure that the build is legal at the time of construction by applying for a lawful development certificate and make sure that your conversion follows permitted development rules, including using materials that are similar to the existing property. 

Alternate Options if You are Unable to Do a Hip to Gable Loft Conversion

Hip to gable loft conversions might not be possible in some properties. If that is the case for you, then there are other options to explore. Some good alternatives to consider include side dormers, which are best for detached or semi-detached properties and create a new addition to the side of the roof, or a mansard loft conversion, which is constructed by raising the party wall and is typically found at the rear of the property.
