Many of us started working from home in the coronavirus pandemic - and never went back.
Now, office space in many cities around the world is standing empty. We visit Mumbai, New York and London, where an increase in home working means buildings in business districts standing empty. And Singapore, which seems to be bucking the trend, with demand as high as ever.
We also hear from the CEO of US-based commercial real estate company Remax - are we witnessing the end of the traditional office?
