Removing a Load-Bearing Wall During Your Self-Build Extension
If you’re self-building an extension in Hertfordshire, removing a load-bearing wall can open up your living space and create the home you’ve been dreaming of. But it’s one of the most critical structural changes you can make, and doing it safely is essential.
At Wall Away Ltd, we specialise in load-bearing wall removal and RSJ installations, helping self-builders transform their homes without compromising safety or compliance.
What is a Load-Bearing Wall?
A load-bearing wall supports the weight of the structure above it, including floors, roofs, and other walls. Unlike non-load-bearing walls, it cannot be removed without proper planning and reinforcement.
Tip: Always have a structural engineer assess your wall before making any alterations.
Do I Need an RSJ to Remove a Load-Bearing Wall in My Self-Build?
Yes. When you remove a load-bearing wall, a steel beam (RSJ) is typically installed to take over the weight the wall was supporting. RSJs are custom-designed to fit the span of your opening and the load it must carry.
Benefits of using a professional team for RSJ installation:
Correct sizing and placement
Compliance with UK building regulations
Reduced risk of structural damage
How Long Does It Take to Remove a Load-Bearing Wall?
The duration of a wall removal depends on:
The size of the wall
Complexity of the RSJ installation
Site access and location
Existing structures like joists, ceilings, or soil pipes
For a typical self-build extension, most load-bearing wall removals take 2–5 days, including preparation and RSJ installation. Larger or more complex projects can take longer.
Tip: Coordinate your wall removal with your other trades to minimise disruption.
How Disruptive is Wall Removal During a Self-Build?
Even with a professional team, wall removal will create some temporary disruption:
Dust and debris
Noise from cutting and beam installation
Restricted access to parts of your home
Pro tips to reduce disruption:
Schedule work in phases to keep your living area usable.
Use dust sheets and temporary barriers.
Keep communication open with your contractor and builders.
Can I Remove a Load-Bearing Wall Myself?
No. DIY removal of load-bearing walls is extremely risky. Incorrect installation can cause:
Sagging ceilings
Cracks in walls
Structural failure
Hiring a professional team like Wall Away Ltd ensures your self-build is safe, efficient, and compliant with UK building regulations.

FAQs
How do I know if a wall in my home is load-bearing?
Load-bearing walls support the weight of the structure above, such as floors or roof beams. Signs include walls that run perpendicular to floor joists, walls that have beams or columns above, or walls that align with walls on floors above. Always get a structural engineer to confirm before removal. Learn more about load-bearing wall removal.
What is the cost of removing a load-bearing wall in Hertfordshire?
The cost varies depending on wall size, complexity, and whether steel beams (RSJs) are required. On average, homeowners in Hertfordshire can expect to pay between £2,500 and £6,500, including design, engineering, and installation. Check our detailed guide on RSJ installations.
Do I need planning permission to remove a load-bearing wall?
Generally, internal wall removal doesn’t require planning permission unless it affects a listed building, alters the exterior, or changes the property’s footprint. Building regulations approval is almost always required to ensure structural safety.
Can I remove a load-bearing wall in a listed or historic property?
Yes, but it’s more complex. Listed or older homes may require additional permissions and careful planning to preserve original features. Consulting a structural engineer is essential before any work.
How much mess and disruption should I expect from load-bearing wall removal?
There will be dust, noise, and temporary loss of access to the affected area. Disruption can be minimised by protective coverings, careful planning, and choosing a professional team experienced in working around kitchens or living spaces.
How do you support self-builders during wall removal projects?
We provide full project support, from structural assessment and RSJ design to installation and finishing advice. Our team ensures your wall removal is safe, efficient, and coordinated with your ongoing self-build project. Contact us to discuss your project.
What types of beams (RSJs) can replace a load-bearing wall?
RSJs come in various sizes and grades depending on the load and span. Common choices include universal beams (UBs) and spliced beams for wider openings. Our engineers design each beam to ensure structural integrity while maximising open-plan living space.
How long do I need to wait before I can continue my extension after a wall removal?
Typically, work can continue immediately after the structural beam is installed and inspected. Any temporary supports are removed once safety is confirmed, allowing builders to proceed with flooring, walls, or kitchen installations.
What happens if a load-bearing wall is removed incorrectly?
Incorrect removal can cause sagging ceilings, cracks in walls, and even partial collapse. It’s dangerous and expensive to fix. Hiring a professional team ensures compliance with building regulations and prevents structural issues.
Can you remove a load-bearing wall in a basement or attic?
Yes, but it requires careful engineering. Floor and ceiling loads, joist placement, and limited access add complexity. Our team has experience removing walls in basements, lofts, and tricky spaces while maintaining structural safety.
Do I need a structural engineer for every wall removal?
Yes. A structural engineer assesses load requirements, designs the appropriate beam (RSJ), and ensures compliance with building regulations. Their input is essential for safe and effective wall removal.
What are temporary supports used during load-bearing wall removal?
Temporary acrows or props hold the structure above while the wall is removed and the beam installed. They prevent sagging or collapse and are removed once the beam is fully in place and inspected.
How do soil pipes or other utilities affect load-bearing wall removal?
Utilities like soil pipes, water, or gas lines may need rerouting to accommodate the new beam. Our team plans installations to minimise disruption while maintaining safety and function.
Are there ways to save money when removing a load-bearing wall without compromising safety?
Yes. Planning the layout efficiently, combining multiple wall removals, and choosing the right beam size can reduce costs. However, safety should never be compromised—always use a professional team.
