Open-plan kitchens, larger family rooms and better-connected living areas remain extremely popular when renovating older homes.

Often, achieving that transformation requires removing an existing wall.

But before a wall comes down, there is one critical question to answer: is it load-bearing?

Removing a structural wall is very different from removing a simple partition.

What Is a Load-Bearing Wall?

A load-bearing wall forms part of the structure of the building.

It may support floors, roof structures or other parts of the property above it and transfer those loads down towards the foundations.

If that wall is removed without the correct replacement support, serious structural problems can result.

This is why structural alterations should never be based on guesswork.

How Do You Know Whether a Wall Is Structural?

There are clues that an experienced professional may consider, including:

  • Direction of floor joists
  • Position of walls above
  • Original property construction
  • Roof configuration
  • Existing beams
  • Building plans where available

However, these are not a substitute for a proper structural assessment.

Biggin Renovations works with structural steel as part of its wider renovation and extension service and has its own in-house structural engineering capability.

What Happens When a Structural Wall Is Removed?

Where a wall is carrying load, another structural element normally needs to take over its job.

This commonly involves installing a steel beam, often referred to as an RSJ.

Depending on the design, more than one steel member may be required.

The beam itself needs suitable support at each end and the overall solution must be designed for the loads involved.

What Is an RSJ?

RSJ stands for rolled steel joist, although a range of structural steel sections can be used within modern construction.

The correct specification depends on engineering calculations rather than simply choosing a beam that “looks strong enough”.

Factors can include:

  • Span
  • Loads from above
  • Number of floors
  • Wall construction
  • Beam arrangement
  • Required opening width
  • Available support

Temporary Support Is Essential

Before the existing structure is removed, the loads it carries need to be safely supported.

Temporary works are therefore an important part of the operation.

Once the permanent steel structure has been installed correctly, those temporary supports can eventually be removed as part of the controlled construction process.

This is skilled structural work and not simply demolition.

Why Create a Larger Opening?

Structural alteration can completely change an existing property without necessarily increasing its footprint.

Homeowners often remove walls to create:

  • Open-plan kitchens
  • Kitchen-dining rooms
  • Larger family spaces
  • Better garden views
  • Improved circulation
  • Increased natural light

In some cases it is combined with a new extension, creating one large space across both the original and newly constructed parts of the home.

Biggin Renovations specialises in property renovation as well as house extensions, making this type of combined project particularly relevant.

Do You Always Need to Remove the Entire Wall?

No.

Sometimes creating a wider opening provides the desired result while retaining small sections of wall.

The right choice depends on the design, structure and how the room will be used.

Leaving part of the original structure can sometimes reduce complexity while still dramatically improving the layout.

Building Regulations

Structural alterations generally need to comply with Building Regulations.

The structural design and supporting calculations are an important part of demonstrating that the new arrangement can safely carry the required loads.

Fire protection around structural steel may also be required.

Don’t Forget Services

Walls contain more than bricks or timber.

Before alteration, consider whether they contain:

  • Electrical cables
  • Sockets and switches
  • Pipework
  • Heating systems
  • Other services

These may need to be relocated as part of the overall works.

Structural Work and Extensions

A rear extension often requires part of the original exterior wall to be removed to connect the old and new areas.

The structural solution therefore needs to be considered at the extension design stage rather than treated as an afterthought.

Creating Open Space Safely

Removing a wall can be one of the most dramatic alterations you make to a property.

Done correctly, it can transform a series of smaller rooms into a brighter and more practical modern home.

But appearance comes second to structure.

The new space must be properly engineered and constructed so that the building remains safely supported for decades to come.

Frequently Asked Questions

Can I remove a load-bearing wall?

Yes, in many cases, provided a properly designed structural solution replaces the support being removed.

Do I need a structural engineer?

Structural calculations will normally be necessary when altering structural walls. Biggin Renovations has in-house structural engineering capability.

What is an RSJ?

It is a commonly used term for a structural steel beam installed to support loads where walls or other structural elements are altered.

Can I create an opening without removing the entire wall?

Often, yes. A partial opening may achieve the desired layout depending on the property and structural design.

Can structural wall removal be combined with an extension?

Yes. Large kitchen and rear extensions frequently involve structural alterations to connect the existing house with the new space.
