Restoration & Refurbishment

How do I know if a wall crack is structural?

In the last 3 months, we have just completed a loft conversion. Today in my uncle's room, I noticed a large crack going down the corner of the room in his 1st-floor bedroom. This is a shared wall in the middle of the property with the room directly facing our garden. The corner the crack appears is located on the outer wall side. Upon inspection, there is a thick piece of the corner crack came off, this piece included plaster and plasterboard. Upon inserting my fingers in the crack, I can feel a gust of air moving around. I am worried, as we will be converting this room into a bathroom in the next few weeks. Is this a structural issue? I have pictures but unsure how to attach them.
