Structural Calculations for Domestic Extensions

Extending your home is a popular way of gaining extra living space, be it a bigger kitchen area or additional bedrooms for a growing family. Building an extension to your existing home brings a whole new life to the building. It also means, in many cases, you won’t have to move house and can stay where you are in comfort.

The initial planning stage of any building work is vital. To enable the project to be completed to the highest standard, with the best outcomes possible, it’s important to get your plans absolutely accurate. This includes many considerations necessary to comply with building regulations and also the steel beam calculations for extensions.

In most instances, structural supports are required to support load-bearing walls and floors above when alterations are taking place on the ground floor. This is to ensure the safety of your new living space and is also a requirement to meet current building regulations.

Steel Beam Calculations for Extensions

If large panels of masonry are being removed, in certain cases, extra steel support is required for the lateral stability of the building. Additionally, steel supports may be required to support new floor joists or roof structures. Building Control often require checks on new or existing masonry walls, piers and foundations which are supporting new steel beams and thus carrying an additional load than they had previously. It’s vital to have the correct beam calculations for extensions when planning and building.
