Like a construction site

What have they done to my beautiful lab?! 

I got a call to say that Estates had been to say that the supports for the air-con units (that have been in place for years) weren't strong enough and they were going to have to put some 'supports' in place to stop them falling on somebody's head...this is what we've ended up with.

Still waiting for any information on what the actual problem is and when they might get round to a more permanent fix. Oh, the joys.
