I got most of the internal brickwork plasticard in and 3 of the external walls plastered last night. A smooth render was lost at that scale so I've gone back to a rougher texture. I still haven't decided what to do for the office interior yet, I'm torn between just spraying it white and accepting the masking taped edges to the exposed foamcore, cladding it in brickwork, or wallpapering it.
I also put the plasticard hoarding up for the signs and adverts. It helps break things up a bit on the plain walls.
I'll try and get a photo of the walls tonight as I completely forgot last night (I was watching Walking Dead Season 3 and I think I was traumatised!).
