Why Hip to Gable Loft Conversion is the best loft extension type?
If you have hipped roof on a detached house, semi-detached house or end terrace, this sort of conversion is just what you are looking for to create more space.
Want to know the best part? Having a hipped roof usually means the existing loft space is usually limited, and the conversion will make the wasted space usable.
You might be wondering whether Hip to Gable loft conversion is also possible in bungalows and chalets…
…Yes, it is but you need to take extra care! The loft might have not been structured to take the extra load imposed so it is best to consult an architect and structural engineer first.
A Hip to Gable refurbishment is a perfect way to maximise the available space in your home. These conversions fit right in with the rest of the house, and if well designed you will feel like the new found space was always there.

How I can design my Hip to Gable loft conversion?
The original height of the loft is crucial when weighting your options for the Hip to Gable renovation. If the original height is too low, changing from hipped to gable roof will not help with anything. It will cost you a lot of money and all you have done is created unusable space.
Another issue to consider for Hip to Gable loft conversion is access. Having a full staircase is definitely advisable, but your architect needs to position it in a way that will make the most of the loft and the floor below.
Did you ask yourself who will be using the loft space?…
…The usual choices for the function of the loft room are master bedroom with an en suite, second living room, office or a gym space.
But here’s the kicker: Your architect should also consider a new need for natural lighting. Previously loft used as a storage did not require any natural light, however if you are investing for it to take integral part in the house usage, it will need adequate amount of natural light coming in.
As the roof might have not been designed to be used as an integral part of the house it is important to note and check if the roof is fully weather tight and if the roof is a cold or warm roof. In case it is a cold roof, your architect will design additional insulation to improve the living conditions of the space and comply with Building Regulations.
How I can get Planning Permission for my Hip to Gable loft conversion?
Since 2008, Hip to Gable loft extensions are within Permitted Development rights. This means that you need to have your planning drawings ready to apply for a Certificate of Lawfulness (COL). This Certificate is for you if you want to ensure that the conversion is legal under Permitted Development.
However, do check with your local council if they have fully adapted Hip to Gable Permitted Development rightsand if your site does not fall within conservation area or any other areas under Article 4.
Remember… The permitted development rights only cover dwelling houses, not flats or maisonettes.
Even if you have Permitted Development rights, there are still some considerations and limitations you need to abide:
• A volume allowance of 40 cubic metres additional roof space for terraced houses.
• A volume allowance of 50 cubic metres additional roof space for detached and semi-detached houses.
• No extension beyond the plane of the existing roof slope of the principal elevation that fronts the highway.
• No extension to be higher than the highest part of the roof.
• Materials to be similar in appearance to the existing house.
• No verandas, balconies or raised platforms.
• Side-facing windows to be obscure-glazed; any opening to be 1.7m above the floor.
• Roof extensions not to be permitted development in designated areas.
• Roof extensions, apart from hip to gable ones, to be set back, as far as practicable, at least 20cm from the original eaves.
• The roof enlargement cannot overhang the outer face of the wall of the original house.
Your planning drawings for Hip to Gable loft extension should indicate that you comply with these considerations and limitations to get Certificate of Lawfulness (COL) from your council for your loft conversion.
What’s the bottom line?
Almost every successful Hip to Gable loft conversions achieve an extra 60 cubic metres, well exceeding the volume allowance of 50 cubic metres. If you want to create as much as space possible, you may then need Planning Permission for your Hip to Gable loft extension.
It gets worse: The volume allowance includes any previous roof extensions, and even if you have not done any work, the previous owner could have. So if you suspect this to be the case, it would be smart to find out with your local council.
However, securing planning permission is NOT rocket science. In fact, it is pretty straightforward.
All Hip to Gable loft conversions require approval under the Building Regulations. Remember that your architect and structural engineer needs to submit structural drawings, calculations and construction notes to make this application and seek approval.
