Understanding Load Bearing Walls

Load bearing walls are essential to the structural integrity of a building. These walls are responsible for distributing the weight of the upper floors and roof down to the foundation. Without load bearing walls, a building would be unstable and unable to support its own weight.

Supporting walls are typically located in the center of a building or along the perimeter. They are often thicker than non-load bearing walls as they need to be strong enough to withstand the weight they are supporting.

The load distribution function of these walls is critical to the safety and stability of a building. Load bearing walls distribute the weight down to the foundation, ensuring that the building remains level and sturdy. They also help to prevent the building from racking, swaying, or collapsing in high winds or earthquakes.


Structural Walls

Load bearing walls are also referred to as structural or supporting walls. These walls are designed to carry loads from the roof, upper floors, and other structural elements such as beams and columns.

Structural walls must be able to withstand the weight and stress from the floors above, as well as any lateral forces such as wind or earthquakes. They are typically constructed from masonry but can also be timber, which provides the strength required to support the load.

Removing a load bearing (without mitigation) wall can cause structural damage to your property.

The location and number of load bearing walls in a building are determined by a structural engineer during the design phase. The engineer will consider factors such as the weight of the building, the type of soil, and the local building regulations to determine the appropriate wall configuration.


Identifying Non-Load Bearing Walls

While load bearing walls provide support and stability to a building, non-load bearing walls serve a functional purpose. They are designed primarily to divide spaces and provide privacy.

Interior walls can be classified as either load bearing or non-load bearing. Non-load bearing walls do not support any weight from the structure above and you can remove a non-load-bearing wall without impacting the building’s stability.

It is worth noting that not all walls that appear to be non-load bearing are actually non-load bearing. Therefore, it is essential to consult a structural engineer to determine if a wall is non-load bearing before knocking down a wall.


Types of Building Construction and Wall Requirements

Building design construction rely on various factors that impact wall requirements. From the materials used to the architectural design, every aspect is critical in determining whether a wall is load bearing or non-load bearing. An essential factor in understanding wall requirements is the type of building structure.

Types of Building Construction

There are two main types of building structures in the UK:


  • Timber Frame

  • Traditionally built

Timber frame

Timber frame construction in the UK involves using timber framing for residential buildings. This method offers speedier construction, better energy efficiency, and design flexibility.

A timber frame is assembled, then enclosed with rendered block, brick, or cladding and highly. This approach reduces costs, enhances insulation, and allows diverse architectural styles. It’s an eco-friendly choice popular for new homes and extensions in the UK.

The timber frame is structural with roof trusses supported on this.

Most (if not all) of the internal walls will also be timber studs, load-bearing walls support the weight of the first floor. If the wall is perpendicular to the joist then there is a good chance that it might be a load-bearing wall. This is generally a basic load-bearing feature.

If the wall runs parallel to the joist it is unlikely to be a supporting wall.

Load bearing walls are roughly near the center of the house. These walls transfer their structural strain down to the foundations of the house.

The Load bearing walls in your house are thicker than non load bearing partitions

Timber frame construction is very popular in Scotland but not so much in England and Wales.


Traditionally Built

Traditional construction of houses typically involves using materials such as bricks, concrete, and mortar to create the structural framework and walls of a building.

This approach has been practiced for centuries and often incorporates local building techniques and styles. In traditional construction, walls are built on-site by stacking bricks or blocks and bonding them together with mortar. The construction process is generally slower compared to modern methods, as each layer of the structure needs time to set before the next can be added. Traditional houses often have a solid and durable feel due to the thickness and weight of the materials used. While traditional construction methods have evolved with advancements in technology, they still maintain a connection to architectural heritage and craftsmanship.

A load bearing wall may be a timber stud wall or a masonry wall, depending on the style of the house.

Often bungalow walls may not be load bearing walls as the roof trusses do not rely on the walls below to support them.

However, houses with 2 or more storeys will have internal supporting walls


Example properties

Edinburgh or Glasgow tenements:

Removing a wall or part of a load-bearing wall in a tenement building requires careful consideration and expertise due to the structural complexities of these historical structures. Tenements often have load-bearing walls that support the entire building, and altering them without proper assessment can lead to structural instability. Consulting a structural engineer is essential in such projects to ensure the removal is done safely and doesn’t compromise the building’s integrity.

Tenement buildings typically have shared walls with neighboring units, which adds another layer of complexity.

Load-bearing walls usually in tenements are constructed of masonry

A structural engineer will assess the load-bearing nature of the wall, often examining the structure below the wall and above the wall to determine whether the wall is load bearing and its importance for the building’s stability, and propose appropriate solutions to maintain the structure’s integrity. They’ll ensure that necessary reinforcements, like beams or columns, are added to redistribute the loads properly. Working with professionals ensures that the removal of a wall in a tenement is executed safely, preserving the historical value and safety of the building.


New Build or Modern(ish) blocks of flats

Removing a wall in a new build flat requires careful planning and consideration to ensure both structural integrity and compliance with building regulations. Unlike historical structures, new build flats often have more standardized designs and construction methods. However, it’s still crucial to involve a structural engineer to assess the wall’s load-bearing nature and provide guidance on how to proceed.

Before removing a wall, it’s important to determine whether it’s load-bearing or non-load-bearing. A load-bearing wall supports the weight of the structure above it, while a non-load-bearing wall carries minimal or no structural load. A structural engineer will assess the architectural plans, review the building’s construction, and conduct on-site evaluations to determine the wall’s role in the overall structure. Based on their assessment, they will provide recommendations on how to safely remove the wall while maintaining structural stability.

Even in new build flats, there might be instances where walls are load-bearing due to the layout or architectural design. A structural engineer’s expertise ensures that the removal process is carried out safely and that appropriate measures, such as installing support beams or columns, are taken to distribute the loads effectively. Their involvement guarantees that the removal of a wall in a new build flat is executed seamlessly, preserving the aesthetics and safety of the living space.


Victorian semi-detached or detached houses

Victorian houses often feature a mix of load-bearing and non-load-bearing walls, making it crucial to consult a structural engineer before making any modifications. Their expertise ensures that the removal is done safely and that the structural integrity of the house is preserved.

Victorian houses are known for their ornate designs and unique construction methods. A structural engineer will assess the wall in question to determine if it’s load-bearing and if its removal could affect the stability of the house. Load-bearing walls in Victorian houses may support significant weight, including upper floors and roof structures. If the wall is load-bearing, the engineer will recommend appropriate measures, such as installing support beams or columns, to ensure the load is properly redistributed.

Given the historical significance of Victorian houses, it’s important to retain their charm while modernizing the space. A structural engineer’s involvement ensures that the removal of a wall aligns with both safety standards and the preservation of architectural heritage. By collaborating with professionals, you can transform your Victorian house while maintaining its structural integrity and aesthetic appeal.


New build Houses

New build houses are constructed following specific designs and engineering principles, and altering walls in your home will involve a structural engineer. Their expertise ensures that the removal process is safe and that the overall structural integrity of the house is maintained.

Before proceeding with the removal of a wall, it’s crucial to confirm if it’s a load-bearing wall. Structural engineers possess the knowledge to identify load-bearing walls through architectural plans, on-site inspections, and an understanding of the building’s construction. If the wall is load-bearing, the engineer will provide recommendations on how to redistribute the loads and maintain the stability of the house.

The structural engineer’s role extends to evaluating the impact of the wall removal on neighboring components, such as floors, ceilings, and other walls. They ensure that appropriate measures are taken to support any loads that the removed wall previously carried. By collaborating with professionals, homeowners can confidently navigate the process of removing a structural wall in a new build house, transforming their living space while upholding safety and structural soundness.


Building warrants

How do you find out if a wall is load bearing?

A structural engineer will be able to confirm that a wall is load bearing or non load bearing

Load-bearing wall removal always requires a building warrant or building regulations approval regardless of which type of property you own.

You may not require a building warrant for removing internal non load-bearing walls in a house but you still generally require a building warrant to remove non load bearing walls in a flat.


Load-bearing walls and Structural Integrity

Load-bearing walls provide structural support and stability to the building, while non-load bearing walls serve functional purposes like dividing spaces.

Building regulations require that load-bearing walls are adequately sized, strong enough to support the weight of the floors above, and correctly positioned to distribute the load evenly to the foundation. Non-load bearing walls, on the other hand, are generally less chunky.


Architectural Design and Wall Requirements

The architectural design of a building is also an essential factor to consider in wall requirements. For example, buildings with open-concept living areas will require fewer walls than those with many separate rooms.

Local building regulations will also play a role in determining wall requirements. These codes ensure that buildings are structurally sound and safe, and that walls are appropriately classified as load-bearing or non-load bearing.

Common Load Bearing Wall Locations

Load bearing walls are typically found in specific locations within a building. Understanding these locations is crucial for builders, architects and engineers to ensure the structure’s stability and safety.

The Common Load Bearing Wall Locations Include:

  • Exterior Walls With traditionally constructed houses external walls not only provide shelter, but an external wall also may bear the weight of the roof and upper floors making them load-bearing. With timber frame construction it is generally the inner leaf timber frame that supports the roof trusses and the floors
  • Center of the Building The walls directly at the center of many buildings often contains load bearing walls, which help distribute the weight of the structure evenly. If the wall is parallel to floor joists it’s probably not load-bearing.
  • Near Stairwells Internal walls near stairwells are likely load-bearing because they support the weight of the stairs and the people using them.


It’s important to note that these locations are not the only areas where load bearing walls can be found. The location of load bearing walls may vary depending on the building’s design and construction.


Remove a load bearing wall

Removing load-bearing walls is a significant undertaking that requires careful consideration. Before making any modifications to load bearing walls, several factors must be taken into account to ensure the structural integrity of the building is maintained.

Consult a structural engineer to assess whether the existing wall is load bearing and determine the appropriate course of action. They will evaluate the wall’s position, foundation, and connections to upper floors and floors below to determine if the load it is supporting.

Structural engineers use specialised software to calculate loads and evaluate the impact of removing load bearing walls. They will also consider factors like existing building regulations, potential impact on adjacent walls, and the need for additional support structures.

Load bearing wall removal requires a suitable replacement to support the loads previously carried by the wall. Potential replacements include installing support beams into the construction, columns, and other structural elements. These elements must be properly installed and designed to support the building’s weight and distribute loads safely.

A competent contractor will use special load-bearing structures follow the structural engineers instructions.

Modification to electrical, gas and plumbing may be necessary. When removing a load bearing wall, it may be necessary to relocate or adjust electrical, plumbing. Ensure that you hire a qualified professional to make these changes and have them done before closing up any walls.

Consider the impact of load bearing wall removal on resale value. While opening up a space by removing a load bearing wall can be appealing for personal use, it can negatively impact the resale value of a property. It is essential to weigh the benefits and drawbacks carefully before making any permanent structural changes.
