Looking through the window. Immediately under the window was a large wooden potting bench - as long as the window, about 3 feet wide and 2 inches deep. Gone. The facing wall had contained 3 full height shelving units with the world's largest collection of plantpots. The 2 charred remains of planks had held 3 propagators - 1 electric and 2 large normal ones, all of which have melted completely away.
Looking in through the door - and, yes, that is a semi-melted Black and Decker strimmer in amongst the paint explosion.
The corner under the window - where the fire was started. The fire officer thinks 'they' put or poured something flamable through the louvre window. That's the mangled remains of a petrol leaf hoover, the triton workbench and other as yet unidentified 'stuff' plus the ash of the potting bench.
One petrol Flymo, one small electric hovermower, 2 jerrycans.
All that remains of about 50 metres of hosepipe.
I couldn't bring myself to post any more depressing photos, but I can console myself that it could have been so much worse.
