Adding a Storey to Your Home: Extending on Top of a Pitched Roof

Have you ever wondered if you can add a storey onto your home with a pitched roof? The good news is, yes, it’s entirely possible! Here’s a simple guide to help you understand the process and key considerations involved.

Step-by-Step Process

Removing the Old Roof The first step in adding a storey to your home is to remove the existing pitched roof. This is necessary to create space for the new storey. While this might sound daunting, it’s a routine part of the process for experienced builders.

Adding New Walls Once the old roof is removed, the next step is to build new walls on top of the existing structure. These new walls will form the framework for your additional storey. This phase transforms the open space left by the removed roof into a solid foundation for the new level.

Installing a New Pitched Roof After the new walls are in place, a new pitched roof is constructed on top of them. The new roof is designed to match the existing style of your home, ensuring a seamless and cohesive look.

Key Considerations

Structural Integrity Before you start, it’s essential to assess whether your current building can support the additional weight. A structural engineer will need to inspect your home and may recommend reinforcements to ensure everything is safe and secure.

Planning Permission Adding a storey to your home usually requires planning permission from your local council. They will review your plans to make sure they comply with local building regulations and zoning laws. This step is crucial to avoid any legal issues down the road.

Design and Aesthetics It’s important that the new storey blends well with the existing design of your home. Matching the rooflines, materials, and overall style will help maintain the aesthetic appeal of your house. An architect can help ensure that the new addition looks like it’s always been part of your home.

Building Regulations Any new construction must comply with current building regulations. These regulations ensure that your extension is safe, energy-efficient, and sustainable. This includes proper insulation, ventilation, and adherence to fire safety standards.

Access and Logistics Building on top of an existing structure can be more complex than building an extension at ground level. Proper planning is required to manage how builders will access the roof and where materials and equipment will be placed. This often involves the use of scaffolding and cranes.

Cost Adding a storey can be more expensive than other types of extensions due to the complexity and scope of the work involved. However, the added space and potential increase in property value can make it a worthwhile investment.

Expert Consultation To ensure the success of your project, it’s crucial to work with experienced professionals. Architects, builders, and engineers can help you navigate the complexities and make sure everything meets the necessary standards.


In summary, adding a storey onto a pitched roof involves removing the old roof, constructing new walls, and then installing a new pitched roof. While it’s a feasible project, it requires careful planning, professional expertise, and adherence to regulations. With the right team and preparation, you can successfully expand your living space and enhance the value of your home.
