The visible part of the front of the building was removed months ago, hence the tarp over the front for so long. From what I could see they have recently started rebuilding the front. What part have you seen is now missing?
The building has been a frontless hollow cube for a long time now.

With regards to the owner, under Earlsfield the owner was indeed south african, however his company was wound up last year, and the "owners" I have spoken to are an Indian guy and a Asian guy. That's who came to see me when I contacted them last anyway, and claimed to be the owners.

That's not to say there is not something underhanded going on with the old owner of earlsfield, but certainly not the face presented. Which agency did you speak to? I wonder if it was the last vendors?
