We recently built a double storey house with a monument roof colour and the rendered wall colour which looked fantastic was Taubmans 'Abstract'. With fencing in Colorbond fencing colour 'woodland grey', balustrading in a powder coated black colour and garage door in powder coated silver colour with black accents. I think colorbond steel colours which look good with Monument would be Shale Grey, Basalt or Wallaby depending how warm/cool you wanted to go with the colour scheme.

Lan: your intuition is right. They're not finished the job. the wall and ceiling s/b sealed.

As others have said, you could have a single downpipe rather than a pair, and it could be made from colourbond or some other material to match the wall. There's no code requiring two downpipes. The applicable Australian Standard is AS3500.3 - Stormwater Drainage. Unless there's some local requirement (not sure exactly where you live) but I would be highly surprised. A google image search turns up a few good looking options. In fairness to the plumber, as contractors we usually have to allow for the cheapest solution when pricing a job to actually win the contract. So as contractors we sometimes get into the habit of just pricing the most cost-effective options, I've been there myself.
