@simhead - here is your feedback, apologies for the delay. This thing called "real life" is kicking all our judges' butts at the moment!
This is such a cute little build, the exterior treatments you have chosen work really well to help give it an industrial feel. The landscaping is simple, but it really works with the basic exterior, your plant choices fit well and you have made some really great use of the terrain painting tool. The roof line works well and again enhances that industrial feel. You have a good layout inside, it feels like it would 'play' well. I think however, that had you stuck with the industrial theme throughout, it would have felt a much more balanced build, the traditional interiors of the main build feel very luxurious in comparison with the stark exteriors. Your palette works well. My favourite part of this build is that office area, it feels incredibly in keeping with the exterior, I love that exposed brickwork in there!
