Have you ever thought about what your unused attic space could become? With a hip-to-gable loft conversion, your loft space can be transformed into a cosy bedroom, a bright home office, or a fun play area for your kids. It’s an incredibly effective way to maximise your internal space, add property value, and make the most of your home. In this guide, we’ll explore the best uses for a hip-to-gable loft conversion, typical loft conversion costs, planning considerations, and how long the project usually takes.

What is a Hip-to-Gable Loft Conversion? 

If your home has a sloping roof or hipped roof, a hip-to-gable loft conversion is an excellent way to open up valuable space. By extending the sloping side into a gable wall, you gain more headroom and usable roof space, turning an underused attic into a bright, functional room. This is particularly beneficial for semi-detached houses and detached homes, where extending the roof structure makes a real difference to comfort and internal space.

Key Features:

  • Roof Alteration: The sloping side of your roof structure is extended upwards to form a vertical gable end.
  • Increased Space: Extra headroom and floor area make the loft space much more usable.
  • Design Integration: The new gable blends seamlessly with your roof type and roof pitch, preserving your home’s character.
  • Ideal Uses: Perfect for additional bedrooms, stylish bathrooms, or a bright home office with plenty of natural light.
