Corner terraced shop.
I want it to look nice and to some degree notable but not 'f### me what have they done!'.
It's brick front, stone sides*. Larger stones/lintels around door/windows, stone gutters.
I thought a slate grey around doors, windows and gutter,
And perhaps turquoise or sage or something for the larger areas of brick/stone.
*Bottom half is pebbledash, can't decide whether to leave that as-is.
