There are a variety of loft conversions to choose from when it comes to renovating your home. The type you choose will depend upon the style of your house and specifically the style of your roof.
If your home has a hipped roof, you might feel limited by the attic space available. A hip to gable loft conversion is one of the best ways to maximise this space, turning a potentially underused area into an extra bedroom, home office, or even a gym.
Hip Roof vs Gable Roof: What’s the Difference?
What Is a Hip Roof?
A hip roof is a type of roof where all four sides slope downwards towards the walls, rather than having vertical gable ends. You can often see this design on semi-detached and detached houses, as well as bungalows.
Despite being known as quite sturdy, this design tends to reduce the amount of loft space available, making it harder to create a functional room.
What Is a Gable Roof?
A gable roof has two sloped sides that meet at a central ridge, leaving a vertical triangular wall (gable) at one or both ends. This design allows for a larger attic space with better height and more layout options.
What Is a Hip to Gable Loft Conversion?
A hip to gable loft conversion is created by straightening the sloping roof (the hip roof) and converting it into a gable roof. The gable roof style forms an ‘A’ shape that sits between vertical walls, unlike a hip roof which slopes on all sides forming a pyramid-like shape.
During a hip to gable conversion, the sloping roof is replaced and extended to connect with the newly constructed vertical wall called a gable wall. This increases the headspace and the usable floor space giving you a new room in your house. Hip to gable loft conversions are one of the most common types of loft conversions and are most suitable for semi-detached properties, end-terrace houses and detached properties built between the 1930s and 1950s that have hip roofs.

Why Should I Have a Hip to Gable Loft Conversion in My Home?
If you want to maximise the amount of usable floor space you have in your loft and you have an existing hip roof then a hip to gable loft conversion might be the best option. Converting a loft in this way will also maximise the headroom for the new living space as well as the loft staircase which creates a comfortable and spacious area.
If you live in a semi-detached home, detached house, or bungalow with a hip roof, then a hip-to-gable loft conversion will be suitable for your home. Mid-terrace properties are not suitable for this type of loft conversion because they lack a gable wall; however, some end-of-terrace properties can accommodate a hip to gable conversion.
What Types of Homes Are Suitable for a Hip to Gable Loft Conversion?
Hip to Gable Dormer Loft Conversion
This involves combining a hip to gable extension with a rear dormer, maximising both headroom and floor space. It works well for those looking to create a large master bedroom, en-suite, or multiple rooms in one loft.
Detached Hip to Gable Loft Conversion
This is also called a double hip to gable loft conversion, where both sloping sides of the roof are extended to form vertical gable walls, doubling the available loft space.
Semi-Detached Hip to Gable Loft Conversion
This type of loft conversion extends the outer sloped side of a semi-detached house and it’s often paired with a rear dormer for additional headroom and floor space.
Bungalow Hip to Gable Loft Conversion
A bungalow hip to gable loft conversion can completely transform a single-storey home, turning the loft into a full upper floor. It’s a popular option for growing families, or those needing extra bedrooms without moving house.

Pros & Cons of a Hip to Gable Loft Conversion
Pros:
- More headroom and usable floor area
- Adds value to your property, increasing resale potential
- Blends seamlessly with the roof for a more natural look than other types of loft conversions
Cons:
- Not suitable for all types of homes – only works for properties that have gable ends
- Can be more expensive than a dormer conversion due to the structural changes involved
Do You Need Planning Permission for a Hip to Gable Loft Conversion?
In most cases, a hip to gable loft conversion falls under permitted development rights, meaning you won’t need planning permission unless your home is in a conservation area or it’s listed. If you’d like to learn more gov.uk’s technical guidance on permitted development rights for householders is a good resource.
However, it’s still a good idea to apply for a lawful development certificate. This will help you prove your build was legal at the point of construction. Additionally, there are design rules you will need to follow concerning volume allowance, building materials, and various structural details. You can learn more about the relevant criteria from this handy guide we’ve put together.

Hip-to-gable loft conversions are no different and will increase the value of your property especially if the loft is turned into a loft bathroom or loft bedroom. Hip-to-gable conversions are often combined with a rear dormer loft conversion to maximise the floor space and head height even more.

Ensuring your loft conversion is fully insulated and has optimised windows also brings added value by making the hip to gable conversion energy efficient which can help to reduce household energy bills.
How Long Does a Hip to Gable Loft Conversion Take?
