We can install a frameless 8mm hinged glass door inside your existing door so you don't need to replace it. Then, between the new inner door and the existing door you place any venetian of your choice. This photo is an example with shutter blinds inside a double glazed window by Euroglazing in Sydney. ...

They look like steel doors but after a quick Google search nothing came up in Qld, only Melbourne and Sydney. I guess you'd already done this too hence your question. You could always order from interstate or maybe use aluminium instead. Maybe try a local heritage architect as they may have a local contact.

Nerida, I would probably use Dulux Vivid White, which is better than Dulux Whisper White for trim as it is a purer white. Woodland Grey will work with gutters and downpipes, although with the yellow tones of the brickwork I would get samples of other colours in the blue/grey range which will counterbalance the yellows. Colorbond Deep Ocean and Colorbond Ironstone could be options. The underside of your verandah looks like it may have been stained timber at one stage, but has been painted brown and concealed any grain? I can't quite make it out from the photo? If this is the case then consider a fresh paint colour such as a quarter strength of your gutter and downpipe colour. There is no rule saying that all eaves have to be white. You can't lime wash over paint that conceals the timber grain. I will be in Adelaide mid-October if you want to set up a Dr Retro House Call colour consultation for your home. Best of luck, Dr Retro of Dr Retro House Calls
