Hip to gable loft conversion

Hip to gable loft conversion

Trying to accommodate the entire family in a small house can be a quite daunting task. Not only is moving out very time consuming, but it could also leave quite a big dent on your pocket. From changing kids’ schools to more time spent on the daily commute, moving into a new house is out of question for most of the families.  

With an already hipped roof, you are wasting valuable space by not converting your loft. A hip to gable loft conversion can solve all of your low space problems by providing an entire room’s space or more, up above in the attic. If you have a detached or a semi-detached house, or your property has a hipped roof, then you qualify for a hip to gable loft conversion. This is pretty much all that is required for you to get started. 

What is a hip to gable loft conversion?

As the name suggests, the hipped roof is replaced by a gable roof in this type of loft conversions. Typically, a hip to gable end loft conversion involves removing the hipped part of your roof at the side and erecting a gable end in its place. Floor steels are also installed across the length of the added space for support and sturdiness. Moreover, the addition of the gable extends your floor to the total footprint area of your house. 

Things to keep in mind:

As a homeowner, you would be naturally inclined to dive right into the process, without wasting any time, and get started at the earliest. There are still some practical considerations that need to be addressed and paid heed to, in order to make the best out of a hip to gable loft conversion.

Planning Permissions:

While small amounts of structural changes to the properties are exempted from additional planning permissions by the law, it is still advisable for UK homeowners to check in with the local authorities, to be on the safe side. An approval from the local body will provide peace of mind and also ensure that you are not violating any regulations or laws. 


Before even getting a quote or choosing the possible use for converted loft, you need to make sure that a hip to gable conversion is suitable for your home in the first place. For instance, a hip to gable conversion is not possible on a mid-terraced house with adjoining neighbouring buildings on both sides. Similarly, some properties designed specifically with a hipped wall may not qualify for a hip to gable loft conversion. After all, you are looking to add useful space to your home that can serve a specific purpose. Choosing a hip to gable conversion for an incompatible roof type may result in cramped space with insufficient headspace, which is contrary to the idea of a loft conversion.

More windows mean more light:

In addition, any structural damage to the roof structure found during the project may also delay the process. Such damages are often hidden and are only found when the hipped part of the roof is removed for replacement with a gable end. These damages can impact the integrity of your roof and may need to be repaired before the work is resumed on the loft conversion project. We know that this can be a huge disappointment for homeowners, however, safety always comes first and it is necessary to make sure that your roof can support the additional weight. 

Word of Advice:

Access is of prime concern when dealing with loft conversion. An ill-planned staircase can eat a lot of useful space, decreasing the value provided by your loft conversion. Similarly, if you coordinate with your architect to work out a plan that uses the least amount of available space, then the same results can be achieved without sacrificing valuable space.
