Understanding Hip to Gable Conversions
A hip to gable conversion is a popular way to transform your home, creating extra living space by altering the roof structure. This type of conversion involves significant changes to the roof, particularly if your property has a hipped roof—a roof with all sides sloping downwards.
Roof Structure Changes
The main change in a hip to gable conversion is the change of the hipped end of the roof into a vertical gable end. This process involves extending the existing roofline and constructing a new vertical wall. By doing so, you replace the sloping side of the roof with a straight wall, which not only alters the look of your home but also adds substantial space to your attic area.

Vertical Wall Creation
Creating a vertical wall is a crucial step in the conversion. This new wall matches the exterior of your home and supports the extended roofline. The result is an open attic space with more headroom and usable floor area. This change is not just about aesthetics; it significantly increases the functionality of your home.

Factors Influencing Hip to Gable Costs
When planning a hip to gable conversion, several factors can impact the overall cost. Let’s explore these elements to help you understand where your money goes and how to manage your budget effectively.
Conversion Size
The size of your conversion is a primary cost driver. A larger loft space requires more materials and labor, which increases expenses. For instance, converting a 40 square meter loft could cost significantly more than a smaller space. The larger the area, the more you’ll spend on structural beams, flooring, and insulation.
Window Choices
Windows play a crucial role in your loft conversion, influencing both aesthetics and cost. Standard windows range from £160 to £2,000 each, while dormer windows can be pricier, costing between £4,000 and £6,000. The type and number of windows you choose will affect your budget. Opting for energy-efficient, double-glazed windows may have higher upfront costs but can save on energy bills over time.
Plumbing Needs
If you’re adding a bathroom, plumbing costs can add up quickly. Plumbers charge between £30 and £50 per hour, and installing a bathroom can cost between £4,500 and £6,000. Consider the location of existing plumbing, as extending pipes over long distances can increase labor and material costs.
Internal Walls
Creating new internal walls to divide your loft space can also affect costs. Materials for internal walls, like plasterboard, aren’t overly expensive, but labor costs can add up. Plasterers typically charge £30 to £50 per hour to finish these walls, providing a smooth and polished look.
Electricity
Electrical work is essential for any loft conversion. Electricians charge between £50 and £120 per hour. You’ll need to budget for installing sockets, lighting, and possibly rewiring if your existing wiring is outdated. An inspection by an electrician is crucial to ensure safety standards are met.
Understanding these factors will help you plan your budget effectively. By considering the size of your conversion, window choices, plumbing needs, internal walls, and electricity, you can manage costs and make informed decisions.
Next, we’ll dive into the benefits of hip to gable conversions and how they can add value to your home.
Benefits of Hip to Gable Conversions
A hip to gable conversion offers numerous advantages that make it a popular choice for homeowners looking to improve their living space. Let’s explore the key benefits:
Extra Space
One of the most significant benefits of a hip to gable conversion is the addition of extra space. By changing the sloped side of your roof into a vertical wall, you create more headroom and usable floor area. This can add at least 20 square meters of living space to your home, making it ideal for a master bedroom, office, playroom, or even a home cinema.

Home Value Increase
A hip to gable conversion can significantly increase your home’s market value. According to Nationwide, such conversions can boost your property’s value by 10% to 20%. This makes it not only a practical choice for expanding living space but also a smart financial investment. When it comes time to sell, potential buyers will appreciate the added space and versatility.
Natural Light
Adding windows to your newly converted loft can flood the space with natural light, creating a bright and welcoming environment. Larger windows or skylights can be incorporated, reducing the need for artificial lighting and enhancing the overall aesthetic of your home. This influx of natural light can transform a previously dark attic into a vibrant, airy room.
Energy Efficiency
A hip to gable conversion is also an opportunity to improve your home’s energy efficiency. By installing new insulation, you can reduce heat loss and potentially lower your energy bills by £240 to £445 per year, according to the Energy Saving Trust. Additionally, opting for double-glazed windows can further improve energy efficiency, keeping your home warmer in the winter and cooler in the summer.
These benefits make a hip to gable conversion a compelling option for homeowners looking to maximize their living space and improve their property’s value. Whether you’re planning to stay in your home for years to come or considering selling in the future, this type of conversion offers both immediate and long-term advantages.
Next, we’ll address some frequently asked questions about the costs associated with hip to gable conversions.
Frequently Asked Questions about Hip to Gable Cost
Is hip to gable more expensive?
Yes, a hip to gable conversion is generally more expensive than simpler loft conversions like the Velux option. This is due to the complexity and structural changes required. The process involves altering the roof structure to create a vertical gable wall, which can be more demanding and time-consuming.
The cost can vary depending on the type of property. For instance, a full hip to gable conversion for a detached home can range from £90,000 to £100,000. Meanwhile, combining a hip to gable conversion with other features like dormer or mansard extensions will increase the overall cost but also add more space and value to your home.
How long does a hip to gable conversion take?
The timeline for a hip to gable conversion can vary based on several factors, including the size of the project, the complexity of structural changes, and the availability of materials and labor. On average, you can expect the project to take between 8 to 12 weeks.
However, potential delays can arise due to unforeseen issues such as bad weather, structural surprises, or delays in obtaining necessary materials. It’s wise to plan for these potential setbacks by including a buffer in your project timeline and budget.
Do I need planning permission for a hip to gable conversion?
In many cases, a hip to gable conversion falls under permitted development, which means you may not need formal planning permission. However, there are exceptions. If your property is in a conservation area, World Heritage Site, or a national park, you will likely need to apply for planning permission.
Regardless of the planning permission requirement, all loft conversions must comply with building regulations. These regulations ensure that the conversion is safe and meets standards for structural integrity, fire safety, and energy efficiency. It’s essential to consult with your local planning authority (LPA) or a professional to confirm whether planning permission is required for your specific project.
