Bi-Fold Door Opening Installation in Dunstable
Creating larger openings for bi-fold doors is one of the most effective ways to completely transform the feel of a home. This recent project in Dunstable involved creating a brand-new structural opening to allow for the installation of modern aluminium bi-fold doors — opening the property up to the garden and bringing significantly more natural light into the space.
Our clients wanted a cleaner connection between their indoor and outdoor living areas while modernising the rear of the property at the same time. To achieve this safely, the existing masonry needed to be removed and replaced with a structural steel beam capable of supporting the load above.
The Project
The existing rear elevation included a smaller window opening that limited both light and access into the garden. The goal was to remove a substantial section of the external wall and create a much wider opening suitable for large bi-fold doors.
Because this was a structural alteration to an external wall, the work required:
Structural calculations
Temporary support installation
Building Regulations compliance
Coordination with the door supplier and installer
This is the kind of project where precision matters. Even small discrepancies in measurements or steel placement can affect the final door installation and finish.
Structural Wall Removal and RSJ Installation
Once the structure had been assessed and the calculations completed, the new opening was carefully prepared and temporarily supported before the masonry removal began. As with all external structural alterations, this stage required precise sequencing to ensure the load above remained fully supported throughout the works.
A structural steel beam (RSJ) was then installed to safely transfer the load above the new bi-fold door opening. This is a critical part of any load-bearing wall removal project, as the steel beam effectively replaces the structural support previously provided by the masonry wall. Correct RSJ installation ensures the property remains structurally sound while allowing for the much larger glazed opening below.
Projects involving bi-fold door openings often appear straightforward from the outside, but structurally they require careful planning, accurate steel calculations, and professional installation — especially when working with external load-bearing walls. That’s why homeowners across Hertfordshire and Bedfordshire regularly use Wall Away Ltd for both load-bearing wall removals and steel beam installations when creating open-plan living spaces or larger openings for bi-fold doors.
Full Compliance Completed
All structural and compliance elements of the project were completed as part of the installation process, ensuring the opening met current Building Regulations standards.
The bi-fold doors themselves were supplied and fitted by HBD Systems, helping bring the final vision together with a clean, modern finish.
Why Homeowners Are Choosing Bi-Fold Door Openings
We’ve seen a significant increase in homeowners across Hertfordshire, Bedfordshire, and surrounding areas investing in larger glazed openings and bi-fold door installations.
The benefits are substantial:
Increased natural light
Better garden access
Improved open-plan living
Enhanced property value
A more modern appearance
But achieving that seamless finish starts with the structural work behind the scenes.
Why Structural Expertise Matters
When enlarging openings for bi-fold or sliding doors, it’s critical that the load above is correctly supported. Improper structural alterations can lead to:
Cracking masonry
Sagging lintels
Door alignment issues
Long-term structural movement
