A hip-to-gable loft conversion involves more than changing the shape of the roof. Replacing the sloping hip with a vertical gable affects how the roof is formed and supported, so structural assessment and careful construction planning are essential.
As a dedicated hip-to-gable loft conversion specialist, we consider how the new gable wall will be supported, how the ridge and existing roof structure will be altered, and how the conversion will connect with the rest of the property. Head height, staircase position and the intended room layout are considered alongside these structural requirements.
The roof alteration also changes the external profile of the home. We therefore consider its proportions, the surrounding properties and the proposed roofing and wall materials as part of the wider design.
A hip-to-gable conversion replaces the inward-sloping side of a hipped roof with a vertical gable wall. The existing ridge is extended across to meet the new wall, creating additional internal volume beneath the altered roof.
This type of conversion is commonly associated with detached and semi-detached homes. It may also be suitable for some end-of-terrace properties with a hipped roof.
The resulting space could be used for a bedroom, bathroom, office or a combination of rooms. What can be accommodated will depend on the roof dimensions, available head height, staircase position and wider layout of the property.
Because the external roof profile changes, the proportions and choice of materials call for careful consideration. Suitability and planning requirements must be assessed for each home.
We begin by discussing your property, the additional space you need and how you would like to use the converted loft.
Step 2: Property Assessment
We inspect the existing hip, ridge, roof structure, supporting walls, available head height and staircase options. Access, neighbouring properties and the external appearance of the proposed alteration are also considered.
Step 3: Project Proposal
We prepare a proposal based on the agreed requirements and findings from the assessment. This sets out the anticipated scope of work and brings the proposed layout together with the structural and construction considerations.
Step 4: Professional Coordination
Where required, we coordinate with architects, structural engineers, Building Control, party wall surveyors and other relevant professionals. We also establish whether the proposal may fall within permitted development rights or demand a planning application.
Step 5: Preparing for Construction
Once the necessary design work and approvals are in place, we organise the site team, specialist trades, materials and construction programme.
Step 6: Managing the Build
We coordinate the structural alterations, formation of the gable, roofing and internal work through a managed programme. Homeowners have a clear point of contact and receive regular communication as the project progresses.
Step 7: Completion and Warranty
We undertake our quality checks and coordinate the relevant final inspections and approvals. The completed loft conversion is supported by Nuloft’s 10-year independent warranty, with the precise coverage confirmed in the project documentation.
Why Nuloft for Hip to Gable Loft Conversion Services?
Replacing a sloping hip with a vertical gable changes both the roof structure and the external profile of the property. Nuloft manages these requirements as part of the wider loft design.
Specialist Structural Roof Knowledge
We consider how the ridge will be extended, how the new gable will be supported and how the alteration affects the existing roof. Head height, staircase position, external proportions and material choices are assessed alongside the proposed layout.
Chartered Delivery from the First Assessment
Our professionally accountable approach provides clear oversight from the free initial consultation through construction and quality checks. The completed conversion is supported by Nuloft’s applicable 10-year independent warranty, subject to its terms.
The precise scope depends on your property, the approved design and the agreed specification. Where applicable, a hip to gable loft conversion may include:
– Coordination of the agreed architectural and structural requirements
– Structural alterations to the existing hipped roof
– Extension and support of the existing ridge
– Formation of the new vertical gable wall
– Structural steelwork or other supporting elements where specified
– Roofing, weatherproofing and agreed external finishes
– Windows or rooflights where included in the design
– A new staircase and associated alterations
– Insulation and relevant fire protection measures
– Internal walls, doors and carpentry
– Electrics, plumbing and heating where specified
– Plastering and agreed internal finishes
– Coordination of relevant inspections
– Applicable completion documents and independent warranty
Not every item will apply to every conversion. Your project proposal will define what is included, excluded or dependent on planning, surveys, design development or third-party approval.
If you are considering a hip to gable attic conversion for your London home, start with a free initial consultation.
We can discuss your existing roof, the space you want to create and the structural, layout and planning considerations likely to influence the project. Suitability cannot be determined from the roof style alone, so the property and proposed design must be assessed individually.
What are The Benefits of a Hip to Gable Loft Conversion
Replacing a sloping hip with a vertical gable can provide multiple practical benefits where the property is suitable:
– More full-height space towards the side of the loft
– A wider and more usable internal floor plan
– Greater flexibility when planning bedrooms, bathrooms or workspaces
– More practical options for storage and circulation
– Additional flexibility when considering the staircase and room layout
– The possibility of combining the alteration with a rear dormer
The amount of additional space will depend on the dimensions and structure of the existing roof. A property assessment is required to understand how these benefits may apply to your home.
The appropriate configuration will depend on the existing roof form, property type and relevant planning and structural requirements.
Standard Hip to Gable Conversion
A standard conversion replaces one sloping hip with a vertical gable wall. It is commonly considered for semi-detached homes and end-of-terrace properties where the roof slopes inwards at the exposed side.
The alteration can create more usable space across that side of the loft, although the final layout will still be influenced by head height, staircase position and the remaining roof slopes.
Double Hip to Gable Conversion
Some detached homes have a hipped roof at both ends. Where the property and design allow, both hips may be replaced with vertical gable walls.
A double hip to gable conversion can create additional internal volume across both sides of the loft, but it also involves more extensive structural and external alterations. Its suitability depends on the roof structure, proportions of the property and relevant approvals.

This was my first every building project so a very daunting experience however Guy and his team were amazing. They were not only supportive and reassuring, but they were flexible with the change and development of my loft conversion project as it evolved. I had several companies quote for the job, but it was Guy’s honest and realistic approach to the plan of work and budget that made my decision to use them which paid off because my daughter now has her dream room.
The team that completed the physical build were nothing short of amazing lead by the most wonderful man Kosta who took such pride in the work and was ridiculously accommodating.
Having a bunch of strangers in your home for 6x weeks could have been very disruptive especially with young kids at home however they were respectful, friendly and other than a few particularly dusty days it was very non-intrusive. The work was finished to a high standard and completed in record time. I was shocked at how quick and efficient the whole build was.
It has completely changed the dynamics of our home and we could not be more grateful to Guy, Kosta and the team for making this happen.

Nuloft renovated our house about three years ago, including a rear extension and loft conversion, and we’re still really happy with the result.
They were easy to work with, good at keeping in touch, and stuck to the budget and timelines, which made a big project feel much more manageable.
Like with any renovation, there were a few hiccups along the way, but they were always quick to sort things out and put things right. Even now, three years later, they’re still really helpful whenever we need advice or have a question about the house.
We love our home and would definitely recommend them to anyone thinking about doing a similar project

Recently had a loft conversion done by Nuloft and was pleasantly surprised at how smoothly it went. Having heard some horror stories about conversions from other companies, I was a little worried about the whole process. However the team were excellent, finished bang on schedule (which was nice) and the results were exactly as planned and costed. Not even a penny over budget. It's nice to come across some old fashioned customer care when most companies just want to grab the money and run.

We worked with Steve and Tani from Nuloft on the full renovation of our Victorian house. From our initial meeting up to project completion they were a dream to work with - professional, courteous, proactive, punctual and with excellent communication and attention to detail throughout. The project was finished on time and within budget and we couldn't be happier with the result. Highly recommend.

We met with 5 different companies before we decided on nuloft and couldn't be happier with our decision! They were extremely professional throughout and provided great advice on how to make most use of the space. We're so grateful and love the end result.

Nuloft completed a beautiful loft conversion on our property in Sidcup. They were really personable and courteous and it was far less stressful than we anticipated.

Not always. Some hip-to-gable enlargements may fall within permitted development rights where the property and proposed work meet the applicable conditions.
Planning permission may be required where permitted development rights do not apply, have been restricted, or the proposed alterations exceed the relevant limits. Conservation areas, listed buildings and local planning restrictions can also affect what is possible.
The planning position should be established for the individual property before work begins. Where appropriate, a lawful development certificate can provide formal confirmation that a proposal is permitted development.
Hip-to-gable conversions are primarily considered for detached, semi-detached and some end-of-terrace homes with a hipped roof.
Having the right roof shape does not automatically make a property suitable. Roof dimensions, structure, head height, staircase position and the relationship with surrounding properties must also be assessed.
The amount of additional space depends on the size, pitch and proportions of the existing roof. Replacing the sloping hip with a vertical wall can increase both the internal volume and the amount of full-height floor space.
A property assessment is needed to determine how much of that space could be used practically within the proposed layout.
Potentially. A hip-to-gable alteration is often combined with a rear dormer to create further headroom and usable floor area.
The combined design must be assessed against the property’s structure, planning requirements and permitted development limits where relevant. The proportions and external appearance of both alterations also need to be considered together.
A loft converted into habitable space will generally require Building Regulations approval. Relevant requirements can include structural stability, fire safety, staircase design, insulation, ventilation and electrical work.
The new gable, altered ridge and supporting structural elements must be considered as part of the wider Building Regulations design.
