If you’re looking to convert your loft, you’ll have come across the terms hip to gable and dormer. These two popular types of loft conversions can turn unused attic space into a usable room, but each has its advantages depending on your roof type, budget and space needs. In this guide we compare hip to gable vs dormer conversions to help you decide which is best for your home.
What is a Hip to Gable Loft Conversion?
A hip to gable loft conversion is for homes with a hipped roof – a roof that slopes on all three sides. This type of conversion extends the sloping ‘hip’ side of the roof vertically to create a straight gable end. This increases the internal headroom and creates more usable floor space in the loft.
Hip to gable conversions are common in detached and semi-detached homes, as well as end-of-terrace properties. They’re ideal for maximising loft space without changing the look of the house too much.
What is a Dormer Loft Conversion?
A dormer loft conversion involves extending outwards from the existing roof slope with a vertical wall and flat (or slightly pitched) roof. This creates a box-shaped structure that adds significant headroom and usable space in the loft.
Dormers are one of the most popular types of loft conversions in the UK because they can be used on most property types, including terraced, semi-detached and detached homes.
Hip to Gable vs Dormer: Key Differences
While both hip to gable and dormer conversions increase the functionality of your loft, there are several key differences:
Roof type compatibility: Hip to gable conversions are only for properties with a hipped roof. Dormer conversions can be used on most roof types.
Structural changes: Hip to gable involves changing the shape of the roof, while dormers are added onto the existing roof structure.
Visual impact: Dormers are more visible from the street and will change the appearance of the property more than a hip to gable conversion.* Planning permission: Hip to gable may require planning permission more often, depending on the extent of the changes, while many dormers fall under permitted development rights.

Which Loft Conversion is Best for Your Home: Hip to Gable or Dormer?
The choice between a hip to gable and dormer loft conversion depends on your home’s structure, planning restrictions and what you want to achieve with the space.
Choose a hip to gable if you have a hipped roof and want to get the most out of your loft with a clean finish.
Go for a dormer if you want a more affordable way to add light, space and functionality to your loft.
In some cases, combining both, a hip to gable with a rear dormer is the best of both worlds. Speak to us today to determine which conversion is the best option for your property.
