Another partially-built timber-frame building has gone up in flames.
The fire broke out on the construction site in Tottenham, north London, on Saturday.
More than 20 fire fighters fought the blaze, according to the Haringey Independent.
It is thought the fire was started by a stray firework.
There has been mounting criticism over the use of timber-frame in construction due to safety concerns. It is the most popular method of building in social housing.
