No down lights in bedrooms. A central pendant fitting with LED bulb, or a central fan with light. Then bedside table lamps. lounge and living spaces- depends on the size of the rooms. In my opinion there is nothing worse than a runway of lights in the ceiling. A central pendant, or two matching pendants, if a long room, always looks the best, in an older home. You could then bring in floor light stands, that will also add to the character of the space. Or a trio of lights in the corner of the room, if space is available. An abundance of down lights, in my opinion, would not look the best. Remember for energy efficiency use LED bulbs.

I some how missed a whole lot of this discussion, it's all coming together beautifully, @kiwimills thank you so much for your lovely comment, if you only knew what an effort it was to get that art work hung, divorce material, he did a great job but after much loud discussion I still ended up with the large hanging not lining up with the bottom of the other frames. I always find that dark spaces work well with darker colours

my suggestions would be to invest in some flatpac cabinets and counters to store frypan, toaster and kettle, wall cabinets for crockery and tall Ikea Billy bookases for pantry (could later be recycled into storage for new laundry, garage pantry?) and invest in small fridge, fanforced microwave and a few hrs work for a plumber and electrician to add a bar sink (drained through wall under bathroom sink) and extra power points to make a more comfortable upstairs living areas as filling the kettle in the bathroom and multiple extension cords will become tedious very soon and try some more adventurous wall colours, keep the walls intact, move the big dining table downstairs for Christmas crowds and then relax on the deck while you plan the new house btw the window sizes don't match the photos to the plans and upstairs and downstairs dimensions do not correspond and need confirming to calculate best arrangements

Yes, if you can I would always install ceiling fans, on very hot nights its always nice to slightly move the air. One piece of advice i would give is be careful how fast they spin on low. We bought fancy looking stainless steel fans and even on low they spun so fast it felt like the roof was going to take off. Ended up changing them to cheaper white ones which were much better. Also, get ones with lights plus bedside lamps for reading as others have suggested.
