Around 40 firefighters were called to the burning building on Vicarage Park at around 6am yesterday (December 4).
They tackled the flames for over two hours before the blaze was brought under control at around 8.15pm.
But not before the roof of the workshop collapsed with LFB saying the structure was “destroyed”.
An investigation has recorded the cause as “undetermined due to the unsafe structure of the building”.
Many people shared pictures and videos of the flames on social media as it lit up the early morning darkness.
Six fire engines from Plumstead, East Greenwich, Eltham, Erith and Lee Green fire stations attended the incident.
There were no injuries and two people left the building before firefighters arrived.
