Station Commander Ian Smith said: "This is an intense fire located in the roof of the building and fire crews are working hard in challenging conditions. We've increased the number of fire engines because of the need for more firefighters in breathing apparatus.
"There is a lot of smoke from the incident and we'd ask local residents to close their doors and windows."
The cause of the fire is not known at this stage.
It comes after around 60 firefighters and eight fire engines tackled a separate blaze in a row of terraced houses in Orpington, south east London.
The London Fire Brigade said two houses were badly affected by the blaze, while an elderly man was treated at the scene after suffering from smoke inhalation.
The brigade said they had the fire under control by 2:15 pm on Tuesday.
While four fire engines and around 25 firefighters were also called to a fire at a waste transfer station in Brentford, west London.
Around 20 tonnes of rubbish were damaged by the blaze, with its cause currently under investigation.
