Simple Beam Design

Planning to remove a load-bearing wall? In many cases, all you need is a simple steel beam to support the structure above. We carry out a site visit to take accurate measurements, assess the layout, and gather all the necessary information. Based on this, we produce a clear set of structural calculations and sketches for submission to Building Control, and to guide your builder during installation.

Connection Design

When multiple steel beams are required in a project—such as supporting intersecting walls or larger spans—we also design the connection details between the beams. Our calculations enable the safe transfer of loads between steel members, often allowing multiple walls to be removed without the need for visible support columns, helping maintain a clean and open interior layout.

Goal Post Frames

If you’re planning to remove an entire rear or side elevation, a goal post frame is an ideal solution. We design frames that include a top beam, vertical steel columns, and supporting foundations. This allows for the safe removal of large sections of wall, and the columns can often be integrated into the side walls—creating an uninterrupted opening with no visible piers.

Letterbox Frames

A letterbox frame (also known as a box frame) includes steel beams at the top and bottom, connected by vertical columns. It’s particularly useful where the structural load needs to be transferred back to the original foundations, removing the need for new pad foundations. This design allows for the complete removal of an elevation while maintaining structural integrity—and, like goal post frames, the steel can usually be concealed within walls for a seamless finish.
