As the station was located on the terrain of the coal mine "Emma" (now totally demolished and gone without a trace) I wanted to get the idea of burning coal or cokes across.
The basic idea was a massive black concrete block, with on the elevations the imprint of fossil ferns (in the old days we could find those everywhere on the mining hills).
And in the centre a round patio, with stained glass walls in red and yellow. Yes, like coal which is burning inside. A fitting image for a firestation.
I was doodling around yesterday and suddenly the image was there. I decided to use the drawing to experiment with digital colouring in GIMP. And here we are: the original sketch and the digital result.
