Bifold and Sliding Doors


Ensuring Structural Stability for Bifold and Sliding Doors

Installing bifold or sliding doors is a fantastic way to bring natural light into your home and create seamless indoor-outdoor living spaces. However, making structural modifications to accommodate these doors requires careful planning and expert assessment. Removing sections of a wall without proper structural engineering can lead to serious safety risks and building regulation issues.

 

The Role of a Structural Engineer

When installing bifold or sliding doors, a structural engineer plays a crucial role in ensuring your building remains safe and compliant. Key aspects we assess include:

1.   Load distribution and the correct specification of a supporting beam (which is always required)

2.   The integrity of the remaining structure after the modification

3.   Compliance with building regulations to avoid future issues

 

A structural engineer will provide detailed calculations and drawings that form part of your building control application. These documents are essential for obtaining approval before any structural work begins.

 

Building Regulations and Structural Integrity

Bifold doors are typically installed on external walls, which are always load-bearing. This means that removing a section of the wall to create space for bifold doors requires careful structural engineering to ensure the building remains stable and secure. A supporting beam is essential to redistribute the load properly, preventing structural failure. As this type of modification directly affects the integrity of the building, approval of building regulations is always required.

 

Accurate structural drawings and calculations play a crucial role in securing approval from building control. At Pavol Zajac Structural Engineers Ltd, we provide detailed, precise documentation that ensures the work is carried out safely, efficiently, and in compliance with all necessary regulations.


Bifold doors are often installed as part of a property extension, whether at the rear or side of a home. Creating a large structural opening in an existing wall requires careful assessment to ensure the load-bearing elements of the building remain secure. When planning an extension, a structural engineer will determine the appropriate support measures to distribute the load safely. Proper engineering ensures the long-term stability of the extension while meeting building control requirements.
