Rear view of the building
in the previous photo.
It turns out that the building started life as "Stepney Road
School". By the 1960's it was in the ownership of British Paints Ltd.
and used as a laboratory.
Around about 1962, it survived an arson attack by a disgruntled former
employee of B.P and was restored for use as a technical service area.
My thanks to Richard Johnson for the above information.
