you need to consider thermal needs, privacy issues, light control, noise control, decorative preferences, size of window, room available around and above window, shape of window, budget...that is why a professional window coverings expert is the best to assist.

Before deciding on a colour, don't forget to consider your kitchen cabinetry, benchtop, splashback, etc (and dining furniture)... for example, if you have a classic hamptons (farmer style) kitchen (and furniture) then don't discount a warm white for the walls... it won't look clinical as the warmth will come from the kitchen cabinetry, etc and dining furniture, e.g. But if you have a "hamptons inspired" look with a slightly more contemporary kitchen cabinetry (and furniture), then in my opinion (all nice options above but a bit too beige'ish for me) so I would suggest a light shade of a warm grey e.g. Whichever way you decide to go, try to narrow it down to 2-3 colours, get the small pot samples and paint each one on all the applicable walls as they will all look different at different angles depending on how they reflect natural daylight and the lights at night time... then you may be able to make a clearer decision. Good luck! :)

Not sure how it would go in Brisbane but what about trying a conifer? They grow fast and very tall. You can shape them or leave them natural. They are plain and certainly not tropical. Maybe speak to a local nursery and find out if they would grow in the sub-tropical climate of Brisbane first, as they are usually in colder climates (Sydney and south). Leightons Green Conifer – Leyland Cypress http://www.evergreengrowers.com.au/shop/hedging-screening/leightons-green-conifer-leyland-cypress/ Your quite limited if there's not enough sun and you dont use bamboo or tropical plants. Many other screening plants or hedges wont get tall enough for that space and climate. I hope you find something.

Thanks for that link Lee. Not sure how I will go getting tile out - I was rather hoping for some kind of 'elbow' profile that I could silicone over the top and create a neat frame. I would if I could grind a channel where the tiles meet and retro-fit that metal trim? 'Me me' and 'Gallifrey' have metal edge too - I did not know that was an option. I certainly would have suggested that. Note to oneself - research before you get in a mess - not afterwards!
