I've got it, thank you so much, I can't tell you how grateful I am!!!

It looks like I have set the transparent objects to grey mode - how do I switch them back?

Thanks for your quick response - I've realised it's definitely something to do with the visibility tool - how do I check class visibilities?

I've been working on a floor plan for days for a University deadline when suddenly the majority of my Design Layer went transparent, as if it had been moved to a different later. However, it doesn't appear to be in any of the other layers (see image). I'm beside myself - my work doesn't appear to be anywhere and a draft is due on Monday. If anyone has any idea what I can do to solve this I would be so grateful.
