Hip to Gable Loft Conversions

A Hip to Gable conversion changes the sloping ‘hip’ end of a roof into a vertical gable wall, increasing loft volume dramatically. This is ideal for semi-detached or end-of-terrace homes where the existing sloped roof restricts internal space.

Why Get a Hip to Gable Loft Conversion?

Many homes have a sloping side roof that really limits how much usable space is available. A Hip to Gable conversion transforms that awkward slope into a vertical wall, giving you much more headroom and floor area.

It’s often combined with a rear Dormer to maximise the loft’s footprint, allowing for larger rooms, better layouts and more storage. It’s also a solution for homes where a staircase won’t fit under the existing roof shape, you gain the structural volume needed to install stairs safely and comply with building regulations.

What Type of Property is a Hip to Gable Loft Conversion Suitable For?

This option is ideal for semi-detached houses with a hipped roof, which naturally limits loft space due to the sloping sides. In areas like Manchester, Stockport, and across the North West, many older semi-detached properties were built with these hip-ended roofs. A hip to gable conversion replaces the sloped side with a vertical wall, creating much more usable space; a solution that specifically suits semi-detached homes, where the open side allows for such an extension.

Benefits of a Hip to Gable Conversion

  • More space – Greatly improves usable loft volume

  • Better layouts – Makes room for larger rooms and stairs

  • Versatile – Often used with a Dormer for best results

  • Future-proof – Ideal if you’re growing your family or want to create a self-contained suite

Things to Consider

  • More complex structurally than a simple Velux or rear Dormer.

  • May affect the symmetry or look of your roof from the front or side.

  • Could require planning permission depending on location and size.

  • Will need to match materials and finishes to existing brickwork or render.

What Rooms Is It Good For?

  • A spacious master bedroom with en-suite

  • Two separate bedrooms, perfect for growing families

  • A self-contained guest suite or rental space

  • A dedicated office or lounge area tucked away upstairs

How Long Do They Take?

Typically around 6 to 9 weeks, especially if being done alongside a Dormer conversion. We’ll give you a full project schedule before we start.

Does It Need Planning Permission (UK)?

Often not. Many Hip to Gable extensions fall under permitted development, but there are limits. We’ll always check local planning rules and apply for a lawful development certificate if needed.

Increase in House Value

A Hip to Gable conversion can increase your property’s value by 20–25%, particularly if it turns your home into a more versatile 4 or 5-bedroom layout.
