Hip-to-Gable and L-Shaped Hip-to-Gable Loft

Hip to gable loft conversion London

A hip-to-gable loft conversion is a conversion that involves changing the sloping side of the property to a flat gable end to increase the size of the loft space. Planning permissions may be required for a hip-to-gable loft conversion, as it changes the outline of the roof.

We also specialise in L-shaped hip-to-gable loft conversions. The key difference between the two – a hip-to-gable loft conversion is generally more expensive than an L-shaped one, but they offer more space and can be more aesthetically pleasing. Whichever type of loft conversion you choose, you must choose a professional company with a commendable track record with this type of conversion.

How do hip and gable roofs differ from one another in loft conversions?


The shape of the building plays an important role in determining what type of roof you should choose. The most common types of roofs are hip and gable. Hip roofs are more suited for buildings with sharper angles, while gable roofs fit better on squares or rectangles. When starting a roofing project, it is important to consider the shape of the house in order to determine what type of roof is best suited to your building structure. Converting from one type of roof to another can be expensive, so a good understanding of these differences can help save time and money when starting a new project.

A gable roof primarily comprises two sloping sides situated at the rising point of the more angular top of a building. However, depending on the overall conversion and the design, these slopes might vary from square to rectangular.

A hip roof has a square-shaped top made up of four separate slants that are all the same length as one. In a rectangular hip roof arrangement, two sides will be constructed as triangles and the other two as trapezoids.


Do you need planning approval to convert the hip to a gable loft?

Hip to gable conversions are permitted by your permitted development rights, just like other loft conversions are. As a result, you are exempt from the subjective nature of traditional planning permission.

However, you should still submit an application for a lawful development certificate so you have documentation that your build was legal when it was completed with the loft conversion. Additionally, you must ensure that your hip to gable extension complies with the scheme’s regulations.

Design guidelines that your hip to gable loft conversion must adhere to:

Remember that not all properties are eligible for permitted development rights. If you reside in any of the following areas, you are not eligible to access the service.

When deciding to undertake conversion or development projects in a conservation area, it is critical to be aware of the planning restrictions and development conditions that local authorities may impose. These regulations can significantly impact the scope of your house project, so it’s important to ensure you understand your rights and obligations before you commit to your loft planning and conversions. 

Depending on the regulations set forth by local planning bodies, houses or buildings in conversion areas can find their rights limited or suspended. Always double-check any documentation or planning permission related to your conversion project beforehand.
