Down by the docks in Charlestown, Cornwall, you find this garage/tiny warehouse.
I like the rubble stone side wall combined with the pale brick front and weathered wooden doors. While not a big building, it's full of character.
Not sure how I'd tackle the side wall. It's probably a job for scribed plaster as embossed Plasticard will look too uniform. I can't remember if Wills have anything suitable in their range as this might work for 4mm scale modellers.
In 7mm though, this would be a fine model and could easily find a home on any quayside layout.
