Do I need a structural engineer for my extension?

If you’re planning on doing a house extension, you may be wondering if you need a structural engineer or an architect. The answer depends on the size and scope of the project. If you’re simply adding a few windows or doors, you probably won’t need either. However, if you’re planning on making major changes to the structure of your home, then you’ll need to hire a structural engineer. They can help ensure that your extension is safe and sound.

If you’re not sure whether or not you need a structural engineer, it’s always best to consult with one. They can assess your plans and let you know if they think you need their services. In some cases, an architect may be able to do the work of a structural engineer. However, it’s always best to err on the side of caution and hire someone who is specifically trained in this area.

Why do I need a structural engineer for an extension?

If you’re planning a single-storey extension, you may be wondering if you need a Structural Engineer. The simple answer is, if your extension needs building regulation approval, then you will need to instruct a Structural Engineer.

A Structural Engineer will assess the existing foundations and structural elements of your property to ensure that they are suitable to support the proposed extension. They will also provide drawings and specifications for the new foundations and structural elements required for the extension.

Instruction of a Structural Engineer is generally a requirement of the building regulations, so if you’re planning an extension that needs building regulation approval, make sure you factor in the cost of instructing a Structural Engineer at an early stage.

How much does a structural engineer cost for house extension?

The cost of a structural engineer for a home extension can vary depending on the size and scope of the project. Generally speaking, a structural engineer will charge between £1,000 and £4,000 for their services.

However, it’s important to note that there is a difference between a structural engineer and a building surveyor. A structural engineer is qualified to provide advice on the design of buildings and structures, while a building surveyor is responsible for ensuring that buildings comply with building regulations.

As such, the cost of hiring a structural engineer may be higher than the cost of hiring a building surveyor. However, it’s worth noting that the advice of a structural engineer can be invaluable when planning a home extension, as they can help to ensure that your project is structurally sound.


If you are thinking about extending your home, you may be wondering if you need planning permission. The answer depends on a number of factors, including the size and location of your extension.

If you are planning a small extension, it is likely that you will not need planning permission. However, if you are planning a large extension, or one that will change the appearance of your home, you will probably need planning permission.

You should also check with your local council to see if there are any restrictions on building extensions in your area. If you are unsure whether or not you need planning permission, it is always best to seek professional advice from a structural engineer or other qualified professional.

What is the difference between planning permission and building regulations approval?

If you’re considering a loft conversion, there are a few things you need to know. First, this sort of build will only usually work on detached or semi-detached houses, as it requires a free sloping side roof. If you’re feeling really ambitious, you can create a vertical gable wall, but most builders don’t recommend it.

Secondly, you need to make sure your ceilings are high enough. Most lofts require a minimum ceiling height of 2.2 meters, though some builders may be able to work with less.

Finally, you need to factor in the cost of the project. A typical loft conversion can cost anywhere from £30,000 to £75,000 (or more), depending on the size and complexity of the project.

Why is a structural engineer necessary?

Planning permission and building regulations approval are two separate things. You need both planning permission and building regulations approval to extend your home.

Planning permission is about whether your extension is in keeping with the look of the surrounding area. It’s also about whether your extension might block someone’s view or stop light from getting into their property. Building regulations approval is about making sure your extension is structurally sound and safe.

You’ll need to get a structural engineer and an architect involved to help with the planning permission and building regulations approval process. They’ll be able to make sure your extension is load-bearing and safe.

Who should I hire first – the architect or structural engineer?

When building an extension on your home, you might be wondering who to hire first- the architect or the structural engineer? While both are important, there are a few things to consider that might help you make your decision.

If you already have an idea of what you want your extension to look like and just need someone to help make it happen, then an architect is probably your best bet. However, if you’re not sure what you want or need help coming up with ideas, a structural engineer can help.

Keep in mind that both architects and engineers will need to work together closely, so it’s important to find someone local that you’re comfortable working with. Whichever professional you decide to hire first, make sure they’re qualified and have experience with projects similar to yours.
