A structural engineer has a key part to play in your build — whether it's a self build, extension, conversion of renovation, they're what make sure your home stands up in the first place, and remains that way. 

However, while you may be familiar with the roles an architect or builder play in your project, knowing when you need a structural engineer can be more obscure for the uninitiated.
