What will happen to Europe’s largest roof garden?

What will happen to the unique roof garden on top of the Derry & Toms building on Kensington High Street? It was once the largest in the world and is still the largest single roof garden in Europe. It was suddenly closed in the beginning of January and there are rumours that the freeholder has instructed an estate agent to try to find a new leaseholder after Virgin, but nobody knows for sure.
