Good news — yes, you can increase the functional square footage of your home upwards, even if your roof has inward sloping edges. That’s where a hip-to-gable loft conversion comes in. In just four to six weeks you could be enjoying your new office, bedroom or nursery at the summit of your house. Find answers here to your who, what, when, where and how questions.
How does a hip-to-gable roof conversion work?
We extend the usable area of your attic by changing the sloped wall (hip) to a vertical one (gable). This straightening up of the top of your property provides headroom across the width of the house to walk around.
Then you can decide how to make this area work for you, which could be:
Velux: affordable; straightforward; keep the slanted front and back; install windows; extra £25K+
This option is available for many types of homes with slanting sides, including:
In fact, it’s only mid-terraces that aren’t viable for this project.
What does a hip-to-gable loft conversion cost?
This average cost includes the construction necessary to implement the structural work. That includes such essentials as:
The end cost also needs to take into account the following:
Choosing standard finishes is the best way to keep prices low. Of course, the size is a major factor too. Two bedrooms, Juliet balcony, dressing area, tailored storage solutions, and a shower room in a luxury high-spec will cost more than a less ambitious alteration.
When is hip-to-gable roof conversion permission required?
There are many reasons to choose this process of enlarging your loft, but you’ll want to know the official situation before you dive in:
Typically considered permitted development
Planning permission usually not required
Conservation areas can impose limitations
Listed status can result in restrictions
Building regulations approval necessary on completion
Reputable building firms help with all of these finer details.

The work that Fittra did for me was a full house renovation – this did not include any new build or extension work but it did include moving a number of internal load bearing walls and extending external openings to install large sliding doors. The work was reasonably complex structurally as the upper floor is steel beam and concrete block construction. Externally all windows and doors were changed, guttering and fascias were changed and a new tiled deck constructed to give an outside/inside feel. Internally, walls were moved, new door openings created or widened to give a modern open plan look and feel.Read More
“Fittra completed a rear extension, loft conversion and full refurbishment of our house in Ealing late last year. This included new bathrooms, heating system (including underfloor heating), electrics and plumbing. When obtaining quotes, Fittra’s prices were in the middle of the three companies who came back to us with costs, but the fact that it was fully itemised (unlike the other costs we received) gave us piece of mind that we knew exactly what we were getting for our money. “Read More
“Can’t speak highly enough of Fittra and the job they did. They completed a rear extension, side return and loft extension and pretty much a full refurbishment of our house and garden in SW London. They not only did an incredible job, but they were also great to work with too. Vadym and Ivan’s team were incredibly efficient and hardworking and really amenable and collaborative. I have recommended them to a few friends subsequently, and will continue to do so.”
Team at Fittra possesses all the attributes necessary to be an excellent contractor: they know their market extremely well; they are diligent, responsive, and yet very understanding with their clients. They are very professional and offer cost saving alternatives when possible. The thing that has impressed me the most is the professionalism, knowledge and helpfulness of all the workers.
“We did our house fully renovation last year July 2019 – December 2019 with Fittra. We are very pleased with the results – our new kitchen (rear extension with lantern roof light), loft conversion, hardwood flooring, underfloor heating, tiling and etc.. Ivan and his team are truly professional. They finished the job with timely manner and customer satisfaction. Their breakdown quotes are easy to understand and easy to work with. We are highly recommended for Ivan, Igor and the team. Great job!!!”

This refurbishment project was absolutely thrilling to accomplish, with a solid team of interior designers and a delightful, intelligible client.

The extension added space to the side and rear of the property; this allowed for […]

Hip to gable loft conversion is mostly found on semi-detached properties with an existing hipped roof. The hip is extended up vertically from the ridgeline to create a gable and a Rear Dormer is formed to the rear of the property.
Hip roofs are more stable than gable roofs. The inward slope of all four sides is what makes it sturdier and more durable. Hip roofs are excellent for both high wind and snowy areas. The slant of the roof allows snow to easily slide off with no standing water.
Doing a double hip to gable loft conversion will be more expensive than a single conversion, however, it will not double the price, as much of the work to carry out the double conversion will already be necessary for the single conversion.
