Does anyone know a place in Melbourne that can make a decorative country rangehood for a 10 ft ceiling

I am thinking of not walk in wardrobes but high quality wardrobes with various fixtures inside.

Any range hood extractor fan would be suitable. It depends on the aesthetics of your kitchen, and your budget as to which style would suit the best. Have you thought about a down draft extractor fan?

Builders markups on upgrades can be large. Unfortunately it doesn’t matter a lot what we tell you if you’re locked into a building contract with your builder. You can’t get alternative quotes and you can’t supply your own. So it’s difficult. But for your own sanity check have a look at the benchtop pricing on diyaustralia.com. They have pricing for the different ranges of major benchtop suppliers on their site.
