Hip to Gable Loft Conversions in London

We design and build high-quality hip to gable loft conversions across London, helping homeowners make better use of the space already within their property. From initial design through to construction, our team manages the process from start to finish.

A hip-to-gable loft conversion works by extending the sloping side of an existing hipped roof outwards to form a vertical gable wall. This creates a much larger internal loft area, improving both headroom and usable floor space.

These loft conversions are especially popular on semi-detached and detached homes where the existing roof shape limits the amount of practical loft space available.

Advantages

  • Creates significantly more usable floor space within the loft.
  • Improves headroom and makes the room easier to furnish.
  • Can be combined with a rear dormer for even more space.
  • Ideal for creating bedrooms, bathrooms, offices or larger master suites.

Best suited for

  • Semi-detached and detached properties with a hipped roof.
  • Homes where the existing loft feels narrow or restricted.
  • Homeowners looking to maximise the full width of their roof space.

House Extension Types

There are several types of hip to gable loft conversions, each offering different looks and levels of space. Here are a few common options:

Double Hip-to-Gable

A double hip-to-gable conversion extends both sloping sides of a detached property's roof to form two vertical gable walls. This can dramatically increase the usable loft area and is ideal for creating multiple bedrooms, bathrooms or a spacious master suite.

Standard Hip-to-Gable

A standard hip-to-gable conversion extends the sloping side of a hipped roof outwards to create a vertical gable wall. This increases the width of the loft and creates a much more practical internal space with improved headroom.

Hip-to-Gable with Rear Dormer

Combining a hip-to-gable conversion with a rear dormer is one of the most effective ways to maximise loft space. The gable increases the width of the roof while the dormer adds further floor space and headroom to the rear of the property.

Hip-to-Gable with Juliet Balcony

A hip-to-gable conversion can be combined with a rear dormer and Juliet balcony to introduce more natural light and create a greater sense of openness. Large glazed doors can also provide views across the garden while retaining the additional internal space created by the conversion.

L-Shaped Hip-to-Gable

An L-shaped hip-to-gable conversion extends the main hipped roof into a vertical gable while also making use of the rear outrigger to create additional loft space. It’s particularly well suited to larger period properties where homeowners want to maximise both the width and depth of the available roof area.

We recently had our loft converted and are absolutely delighted with the result. From the very first meeting with Seb, who took the time to explain all the options and answer our questions, we felt confident we had chosen the right company. He was knowledgeable, professional, and never made us feel pressured at any stage.
Throughout the project, Marius was our project manager. He kept everything running smoothly, communicated clearly, and ensured the work was completed to a very high standard. Marius’s team was very good, hardworking, and clearly took pride in their work, which really showed in the final finish.
The workmanship throughout was outstanding, and the finished loft has completely transformed our home. The attention to detail, quality of finish, and professionalism shown throughout the project exceeded our expectations.
A big thank you to Seb, Marius, and the entire team for delivering such a fantastic loft conversion. We would highly recommend this company to anyone looking to add valuable space and improve their home

I initially came across Simply Easy Refurbs (SER) online and followed their work for some time before my project reached the right stage. When I was ready to proceed, they were one of three companies I invited to quote.

From the outset, SER stood out for their efficiency, professionalism and clear understanding of the brief. As part of my due diligence, I spoke with three of their previous clients, all of whom gave strong, consistent feedback. This gave me the confidence to appoint them for a full refurbishment, including a loft conversion and rear extension.

Throughout the project, SER maintained a high standard of professionalism. Communication was consistent, with regular check-ins to ensure everything remained on track and aligned with expectations.

I would not hesitate to recommend Simply Easy Refurbs to anyone considering a full home refurbishment.

Brilliant execution
We had a very good experience with Simply Easy Refurbs, the communication was always on point whether email, what's app or telephone. The dedicated what's app group is a great platform to check on the progress, share ideas visually etc. We had a good working relationship with all the team but especially with Tomas, our design was executed to a very high standard. All the works carried out was highly professional, done to a high standard and good quality materials were used. All the tradesmen involved worked exceptionally hard sometimes staying later than expected just to get the job done!
We're very happy with the end result. We have a future proof, modern design and the loft conversion has created so much space! We would highly recommend this firm for renovation projects! Thanks again to Seb, Tomas and the team.

We had a great experience with Sebastian and his team. Our mansard loft conversion has added a whole new floor to our flat and provided an amazing new bedroom for our daughter. Our builder Loren and his team were excellent - the work was done on time and to cost; any issues were swiftly dealt with. As expected, we had to get a fire sprinkler system installed - with hindsight we could have started shopping around for a company to do it before building control confirmed it would be necessary; but we were lucky - we found a company who could do it quickly and that meant there was no delay to our project. The aftercare has been fabulous - only today their electrician came back to move a fan in the new bathroom ceiling that was in the way of our new cupboard doors. We couldn’t have asked for more from SimplyEasy Refurbs: we’d recommend them 100%.

I had a very specific idea for my loft and the team made it happen. Great advice, great quality work. I had so many positive comments from friends and relatives. Also, I recently put my house on the market and viewers loved the loft, I have no doubt that the loft helped my house sell faster. Plus, you pay for what you signed for, no hidden fees, furthermore timing was again to what was agreed! I would have no hesitation to recommend SimplyEasy Refurbs!

Dormer Loft Conversions

What is a hip-to-gable loft conversion?

This kind of loft conversion involves extending the sloping side of a hipped roof to create a new vertical gable wall. This increases the amount of usable floor space and headroom available within the loft.

Do I need planning permission for a loft conversion?

Many hip-to-gable loft conversions can be completed under permitted development rights, provided the work meets the relevant size and design restrictions. Planning permission may still be required for properties in conservation areas, listed buildings or projects that fall outside permitted development limits.

How much does a loft conversion cost in London?

The cost of a loft conversion in London will depend on the size of the property, structural work required and the chosen specification. Adding features such as a rear dormer, bathroom or bespoke joinery can also affect the overall cost. Use our project calculator for a general quote.

Which properties are suitable for a hip-to-gable loft conversion?

These loft conversions are generally best suited to semi-detached and detached properties with a hipped roof. They can also work particularly well on bungalows where extending the roof can create a substantial new living area.

Can you combine a hip-to-gable conversion with a rear dormer?

Yes, combining a hip-to-gable conversion with a rear dormer is a popular way to maximise the available loft space. The hip-to-gable increases the width of the roof while the dormer provides additional headroom and floor space to the rear.

How long does a loft conversion take?

Construction times vary depending on the size and complexity of the project, but a hip-to-gable conversion will typically take several weeks to complete. Projects involving larger structural alterations, dormers, bathrooms or extensive internal finishes may take longer.

How much space can a hip-to-gable loft conversion add?

The amount of additional space depends on the size and shape of the existing roof, but a hip-to-gable conversion can significantly increase the usable width of the loft. This can make it possible to create a large bedroom, ensuite, home office or multiple rooms where the original roof space may have been too restricted.
