Thanks boys.
I suspect Ivor Matchinanski was being polite when he posted his practical way of reducing the amount of fire damage. Perhaps he really meant to write "You've burnt too much away you prat!"
On my entering the cooled down building I realised if that was what he was thinking, he was quite right (Something I suspected after the Fire Brigade had left my front garden!)
To try and salvage the building, I've reinstated the middle wall and replaced a few bits n' bobs. Done some scorching on the surviving thatch and added tons of burnt and charred rubble and thatch.
I realise the pictures are getting somewhat repetitive, but they are different - Honest!
Here is my final effort regarding the fire damage.
My thanks to Comrade Ivor 453, for politely providing a tip to prevent any further ballsupskis.
Next I'll make a 'proper' base and add some post battle debris. I promise no fire damaged roof pictures.
Onward and upwards!
Ron
