Very interesting.

I share you concerns with the look of the light. I lived in Cairns for a while and many restaurants etc had high ceilings with lights and fans with a more traditional look. Maybe you could do some internet stalking of hotel websites etc. I'd start with Palm Cove. Good luck.

i also think the outside stairs work better for coming home with the groceries in good weather and, having lived in a similar upstairs bedroom overheating can be a problem: use the best insulation in the ceiling, roof and walls including between the ceiling of the living areas and the floor of the top level (our top level bathroom used to get a hot floor from the heat in the roof space). Shade cloth roller blinds or shutters on the north facing window. (do you like the French balcony?) will improve comfort levels and check out "stack effect" ...having a window open downstairs and a window open on the opposite side of the house upstairs will flush out the house as hot air rises..install closing doors on stairs and hallways to reduce draughts and contain heat in cold weather and add ceiling fans to increase air circulation

Is there a close up image? It's quite hard to make out what it looks like. In the meantime, did you check out the lighting section of the Houzz Products page? There are quite a few wall sconces on there.
