If you live in a semi-detached, end-of-terrace or particular style of detached property and are considering extending into your attic, a hip to gable loft conversion could be the perfect way to unlock space in your home.
By extending the sloping side (the "hip") of your roof into a vertical wall (the "gable"), this type of conversion allows you to maximise your loft’s footprint and create a room that feels spacious, bright, and fully functional.
In this article, we’ll explore exactly what a hip to gable loft conversion involves, what kinds of homes are best suited to it, the design opportunities it opens up – and what influences the hip to gable loft conversion price, so you can make an informed decision about your home extension project.
What is a hip to gable loft conversion?
A hip to gable loft conversion is a structural transformation that changes the shape of your roof to create more internal space. Most commonly used on properties with a sloping side roof – known as a "hipped" roof – the conversion extends this sloping side upwards to form a vertical wall, known as the "gable."
This relatively straightforward structural change can make a dramatic difference. By straightening the side of the roof, you gain valuable head height and floor space, making your loft area much more usable.
It’s particularly popular among homeowners who want to create a full-size bedroom, a generous home office, or even a loft suite complete with an ensuite bathroom and built-in storage.
Compared to simpler loft conversions like rooflight-only or standard dormers, a hip to gable conversion provides a more permanent, seamless extension of your home’s top floor. It also enhances the property's exterior appearance, giving it a more balanced and finished look.
Is my property suitable for a hip to gable loft conversion?
A hip to gable loft conversion is ideally suited to homes with a sloping roof on one or more sides - most commonly found on semi-detached, end-of-terrace, and some detached properties.
These homes often have what’s known as a “hipped” roof, where one or both ends slope inwards, reducing the amount of usable loft space. By converting that sloping side into a vertical gable wall, you instantly increase the available headroom and floor area.
It’s also possible to combine a hip to gable conversion with a rear dormer extension for even more space. This is a popular option for those planning to add a large bedroom, multiple rooms, or an ensuite.
In many cases, a hip to gable attic conversion falls under permitted development, meaning planning permission isn’t always required. However, this depends on factors such as your property type, its location and the scale of the proposed works.
If your home is in a conservation area or is a listed building, you’ll likely need formal permission.
The good news? When you work with a specialist like Bespoke Lofts, we’ll guide you through all the necessary checks and permissions to ensure your project stays compliant from start to finish.
Why choose a hip to gable loft conversion?
There are plenty of reasons why a hip to gable loft conversion is such a popular choice for homeowners looking to extend upwards.
Maximise space and headroom
By removing the sloping section of the roof and replacing it with a vertical gable wall, you significantly increase the usable space in your loft. This means more floor area, better head height throughout the room, and more flexibility in how you use the space.
A seamless, natural extension
One of the big advantages of a hip to gable attic extension is that it blends beautifully with the existing structure of your home. Unlike some loft conversions that can look like an obvious bolt-on, this type of build follows the original roofline and creates a more balanced, permanent-looking extension.
Ideal for larger rooms or ensuite layouts
With more room to play with, it’s easier to plan out a full-size bedroom, generous storage, or even a luxurious ensuite bathroom. If you’re looking to create a true master suite or a multi-functional loft room, a hip to gable layout gives you the space to do so.
Great long-term value
While we’ll look at hip to gable loft conversion price factors shortly, it’s worth noting that this type of conversion typically adds considerable value to a home. By increasing both the square footage and the liveable appeal of the property, you’re making a smart investment that can pay off down the line.
Hip to gable loft conversion price – what to expect
If you are considering a hip to gable loft conversion, you are probably wondering about the cost. While we can’t quote specific figures without a personalised site visit – as prices vary depending on a range of factors – we can certainly shed some light on what influences the hip to gable loft conversion price.
The size and layout of your home
Larger properties or those with more complex roof structures may require additional materials, labour, and time. If your conversion involves structural steelwork or modifications to existing walls or ceilings, this can also affect the overall cost.
The type of conversion you choose
A simple hip to gable extension might be relatively straightforward, but many homeowners choose to combine it with a rear dormer or even a full loft suite with an ensuite bathroom. The more you add, the more your costs will reflect the extra work and features – but the additional space and function often justify the investment.
Internal fixtures and finishes
From flooring and lighting to fitted wardrobes, bathrooms and bespoke storage, the choices you make inside the loft will influence the final price. Higher-end finishes will naturally increase the cost, but they also help create a polished, high-quality space that feels like a true part of your home.
Structural and planning considerations
If planning permission is required – for example, if your home is in a conservation area – there may be additional costs involved in securing the necessary approvals. Likewise, homes that require more extensive structural alterations may require specialist input, which can add to the budget.
Accessibility and site conditions
The ease with which the team can access your loft can affect timelines and cost. For example, homes with narrow side access or limited parking may require different scaffolding or access arrangements.
At Bespoke Lofts, we will always give you a clear idea of what to expect, based on your property and your vision for the space. And we’ll work with you to create a realistic plan that aligns with both your aspirations and your budget.
Design ideas and possibilities
One of the best things about a hip to gable loft conversion is the flexibility it offers. With increased floor space and head height, you’re free to get creative with how you use your new room.
Master bedroom with ensuite – A popular choice, and for good reason. The extra space makes it ideal for a master bedroom with full-sized bed, fitted wardrobes, and a generous ensuite bathroom.
Teen or child’s bedroom – Spacious enough for sleep, play, and study zones. (You can read more about creating the perfect loft room for kids in our earlier blog.)
Home office or creative studio – With natural light from dormer windows or skylights, your new loft space can become the ideal work-from-home retreat.
Multi-use space – Think guest room, reading nook, or yoga zone — a well-designed loft can tick multiple boxes in one.
Whatever you imagine, Bespoke Lofts can help bring it to life with clever planning, beautiful finishes, and solutions tailored to your needs.
