Frequently Asked Questions

Common questions about structural alterations in Surrey.

How do I know if a wall is load-bearing?

The safest approach is to have us carry out an assessment. Generally, walls that run perpendicular to the floor joists, sit above one another on multiple storeys, or support roof structure are load-bearing. We will confirm before any work begins and commission a structural engineer where required.

Do I need a structural engineer for wall removal?

For most load-bearing wall removals, yes. A structural engineer will specify the correct steel beam size and bearing requirements. We work with experienced local engineers and coordinate the whole process. Building control sign-off is also required and we manage this for you.

What is an RSJ and when is one needed?

An RSJ (Rolled Steel Joist) or universal beam is a steel section used to span an opening and carry the load that was previously taken by the wall. They are required for removing load-bearing walls, creating wide openings, and any situation where a large structural span is needed.

Do I need planning permission for structural alterations?

Internal structural alterations generally do not require planning permission but always require building regulations approval. Exceptions include listed buildings or properties in conservation areas. We handle the building regulations process and liaise with the inspector throughout.

Can you remove a chimney breast?

Yes, chimney breast removal is a structural alteration that requires careful propping of the chimney stack above. We install the correct steelwork, make good all surfaces, and ensure the work is signed off by building control. We also advise on whether the breast can be removed at ground floor only or full height.
