Hip-to-gable loft conversions

Services

Expand your home sideways and vertically — perfect for end-of-terrace or semi-detached homes. More space without extending the footprint.

What is a Hip-to-Gable loft conversion?

A hip-to-gable loft conversion replaces the sloping “hip” side of your roof with a vertical gable wall. This creates significant extra floor space and headroom, usually without changing your home’s footprint. It’s a great alternative where adding dormers or extending sideways isn’t ideal.

Because you’re extending the internal volume rather than footprint, hip-to-gable conversions often deliver higher usable floor area per cost compared to some dormers — this can translate into a strong uplift in sale value.

  • Converts a sloping hip roof into a taller, vertical gable end — creating lateral space and headroom.
  • Ideal for semi-detached or end-terrace homes with sloping roof hips.
  • Enables full-height rooms across the loft area, often more volume than a dormer.
  • Often permitted development (but check local rules) with lower cost impact than full-scale extensions.

FAQ's

Questions our clients ask

Have questions about how our process works, what to expect, or how to get started? We’ve answered some of the most common queries below to help you plan your project with confidence.

Contact Us
  • Is planning permission required for hip-to-gable conversions?

    Often falls under permitted development rights, but it depends on property type, conservation status and neighbour consultation. We guide you through that process.

  • How long does a hip-to-gable conversion take?

    Typical build time is 6–12 weeks depending on scale & structural complexity. You’ll receive an estimated schedule in the quote phase.

  • Will it be disruptive?

    Structural works generate noise and scaf­folding. We manage materials, protect your home and appoint a site manager to coordinate any disruption.

  • Can I combine hip-to-gable with a rear dormer?

    Yes — in many cases we design hybrid solutions to maximise space while complying with regs.

  • What about insulation & thermal performance?

    Conversions meet current building regulations; we use high-performance insulation and energy-efficient windows to keep your home comfortable and your bills down.

This was the second time we worked with ICS, having completed a loft conversion with them in 2023. This time they built our kitchen extension and once again the quality of their work was extremely high.  Would not hesitate to recommend ICS or to work with them again.

We have been really very happy with ICS. The company provided a reasonable quote, detailed information on the process and was very responsive to queries. They provided an online portal which helped us to track stages of the build itself as well as finance.

ICS were such a good choice. Absolutely professional and meticulously honest from start to finish. Site manager Stas was always available to smoothly handle any issues that arose. Builders all friendly and competent. Happy with our experience and our new loft.

Adam Rasmussen

I had the pleasure of working with ICS for a series of projects on my property (SE6), including a sideways rear extension, bathroom refit, the addition of a laundry room, complete replumbing, and the removal of an old chimney. The entire crew was not only skilled but also friendly and punctual.

George Randerson

London

We recently had ICSolutions complete a loft conversion, adding two spacious bedrooms and a shower room. From start to finish, the experience was excellent. The team was professional, respectful, and a pleasure to work with. They were always prompt with their timing and kept us well-informed.

Fatima Ali

We just finished a loft conversion with ICS, and I can’t say enough good things about them. They were absolutely amazing from start to finish! Stas, the project manager, was fantastic – completely on top of everything and led the project with such competence and attention to detail.
