As construction work continues apace at West Ham United's magnificent new Stadium on Queen Elizabeth Olympic Park, one of the most striking features of the transformation is the Stadium's stunning new roof.
You can watch for yourself how the massive roof installation project is progressing in this new film, which includes footage taken from our special time-lapse cameras inside and overlooking the Stadium.
Work on the roof has been going on for several months, with eight kilometres of cable netting weighing 930 tonnes lifted and connected, before 112 steel roof rafters, up to 38 metres in length, were also lifted and secured into place.
In November, the first of almost 10,000 panels was lifted into place: with 6,300 solid panels in the rear section, and 3,600 transparent polycarbonate panels at the front. It will take 26 weeks to lift all the panels into place.
The insulated rear section of the roof is key to its special acoustic design, ensuring that the atmosphere of the crowd will bounce around the Stadium and create a cauldron of noise on matchdays.
When the roof is complete, it will enter the record books as the longest cantilevered roof in the world, measuring 84 metres long at its deepest point.
At 45,000 square metres in size, the roof will be twice as big as the original used for the 2012 Games, and will cover every seat in the Stadium, compared to the 40 per cent of spectators in 2012 who sat in the open.
And because it is a cantilevered roof - fixed at only one end - every one of those seats will enjoy a superb, unobstructed view of the action on the pitch, with no roof supports in the way.
While the floodlights that sat on top of the old roof have been removed as part of the transformation work, the 490 lamps they contained will be installed underneath the new roof, providing tremendous illumination to the field of play.
Time-lapse cameras were installed back in the summer enabling supporters to see the Stadium transformation for themselves: two inside the Stadium itself, and one overlooking the entire site from the top of the ArcelorMittal Orbit.
