Blimey. What's the catch?
There is none. Are these plans going to help in your arguments with Mike? Looking forward to seeing them.
No, not even in the slightest, it really would only be to show the staircases and office end of the building (and door swings and windows), so that other people can have a better understanding of the layout, the existing plans are fairly accurate anyway.
I'd hazard a guess that very few people understand the staircases very well.
