What is a Hip to Gable Loft Conversion? 

A hip to gable loft conversion involves extending the sloped (“hipped”) side of your roof and straightening it into a vertical (“gable”) wall. This change expands your roof’s internal space, making it an ideal choice for properties with hipped roofs where headroom is limited.

Key Features:

  • Straightens sloped roof sections into vertical gables.
  • Adds significant floor and headspace.
  • Suitable for detached, semi-detached, and end-of-terrace homes.

Whether you’re in a bustling city or a peaceful rural area, this conversion can unlock the hidden potential of your loft.

Benefits of a Hip to Gable Loft Conversion 

1. Increase Living Space

A hip to gable conversion can add an additional 20m² of usable floor area and increase headroom significantly. This extra space is perfect for creating a new bedroom, a luxurious bathroom, or a multipurpose family room.

2. Boost Property Value

According to Nationwide, a loft conversion can increase your home’s value by 10-20%. This is a smart investment, especially if you’re considering selling your property in the future.

3. Eco-Friendly and Energy-Efficient

Adding insulation during the conversion process can cut heat loss by up to 25%, saving you between £240 and £445 annually on energy bills (Energy Saving Trust). With MariGoldEco’s Free Loft Insulation Grants, you can upgrade your insulation at no cost, ensuring your new loft is warm and efficient from day one.

4. Improved Natural Light and Ventilation

A hip to gable conversion allows for larger windows and skylights, flooding the space with natural light and improving airflow. This makes your loft brighter, airier, and more comfortable.

5. Preserve Outdoor Space

Unlike traditional extensions, this conversion doesn’t encroach on your garden or yard. You’re simply making the most of your existing structure.

6. Avoid the Need for Planning Permission

Most hip to gable conversions fall under permitted development rights, meaning you won’t need to navigate the complexities of planning applications.

Types of Hip to Gable Conversions   

1. Standard Hip to Gable

Ideal for detached and semi-detached homes, this conversion involves straightening one or both hipped ends into vertical gables, creating a larger internal space.

2. Hip to Gable with Dormer

A dormer extension can be added for even more headroom and floor space. Popular options include:

  • Flat Roof Dormers
  • Gable Fronted Dormers
  • L-Shaped Dormers

3. Hip to Gable with Mansard Roof

This option involves altering the entire roof structure to create steeply angled sides, maximizing headspace and floor area. Planning permission is typically required for this type.

Each type of conversion offers unique benefits. Consult a specialist to determine which suits your property best.
