Hip to Gable Loft Conversion: How to Plan, Design, and Build

Hip 2 Gable Loft Extension in Streatham Double Bedroom - Hip to Gable Loft Conversion: How to Plan Design and Build

A hipped roof has three sides rather than a vertical gable end at the side of the house. This limits the amount of usable space in a loft and makes it difficult to do a straightforward loft conversion with Velux windows. It is a common style of roof on semi and detached homes and is sometimes seen on end terraces too. In this article, we cover hip-to-gable loft conversion and how to plan, design, and build.

What is a Hip-to-Gable Loft Conversion?

This type of loft conversion makes the most usable space by removing the hipped section of the roof and replacing it with a gable roof. It is trickier than some other types of loft conversion, such as a side dormer, but if space is limited and there is nowhere suitable to position a new staircase in line with current Building Regulations, a hip-to-gable loft conversion may be the best solution. 

In a hip-to-gable loft conversion, the existing hipped section of the roof is removed, and a new wall is constructed to support a gable. The hip section must be removed first so steel supports can be added, but if the conversion is being done during bad weather, the new gable might need to be built up first, so the roof remains weathertight. 

The addition to the side of the property can be completed to match the existing finish or in a different style. This is a design choice you can make when discussing the project with your builder.

Why is it the Best Conversion Type?

If your roof has a side hip, you have a choice between a side dormer loft conversion or a hip-to-gable loft conversion.

The main advantages of a hip-to-gable loft conversion are that it is more aesthetically pleasing than a side dormer conversion and it can also be constructed in addition to a rear dormer if you need extra space. In addition, it is a suitable conversion type for a bungalow.

The downside of hip-to-gable loft conversions is that it can make a property look imbalanced if it’s semi-detached and the neighbouring property hasn’t had a loft conversion. It’s also unsuitable for a terraced property.

Whereas a side dormer loft conversion is cheaper and easier to construct than a hip-to-gable loft conversion, it doesn’t make the best use of available space and might not be suitable if there is no room for a new staircase. However, if your budget is tight and you can fit in a new staircase that meets Building Regulations, a side dormer loft conversion might be a better fit.

Is Planning Permission Required?

Like most loft conversions, a hip-to-gable loft conversion falls under permitted development rights, so you won’t need to apply for planning permission from your local planning department. However, you will still need to obtain a lawful development certificate once the work has been completed, so you can prove the conversion was legal.

A hip-to-gable loft conversion must adhere to certain rules to be legal, such as the new roof pitch must be the same as the existing roof pitch and similar building materials must be used that match the existing property. 

Check whether your property falls under permitted development rights before you opt for any type of loft conversion. Homes within conservation areas, flats, maisonettes, and listed buildings are ineligible under the scheme. 

If your property isn’t suitable for a hip-to-gable loft conversion, consider what other loft conversions there are, such as mansard conversions, L-shaped dormers, and rear dormers, to see which design will best suit your property. If you need any expert advice, contact SimplyEasy Refurbs today.
