@Relle Belle, I too am OCD about things being straight, even and balanced. We are building our home entirely ourselves and so when we were ready for the electrician, I had already drawn up a lighting plan. I made the sole decision ultimately where every light, fan, powerpoint, light switch and pendant was to go, as it's my home and I have to be forever happy with it but more importantly, when you are personally responsible for the position of every light etc... you start to make better decisions about where they should be and why!! I decided on evenly spacing my down lights with four in each bedroom and a fan in the centre but without a light, as I'm not fond of fans with lights, they tend to take away from the beauty and elegance of downlights. My lounge kitchen dining is one open plan, so I still have the downlights evenly spaced but simply have some lights set on seperate switches, so they have more of a purpose, as I have an open passageway running the full length of this open plan area, so I didn't need those lights on when I only want the lounge lights on for example. Again I have a fan in the centre of the lounge only and in the kitchen, the down lights weren't going to sit squarely over the island, something I couldn't live with, so I chose not to place them in that way at all and have decided on a central task light over the island and I have feature pendants over the dining table. All my lights line up in this large open area and look real good that way and I'm very happy with the changes but I can't stress enough that a simple lighting diagram can be all you need to get the look and feel you want long term. In the bedrooms I'm having pendants, so you have to either already know the size of the bed for each room or physically have the bed for each room as your pendant switch needs to be just past the edge of the bed but not too far away to be over reaching when already in bed to turn the light on or off. I also don't like the largish 100mm+ downlights and have chosen the smaller neater 90mm lights, makes the ceiling look less busy and with a ducted cooling system in the future I wanted to allow space for the ducting vent without having the ceiling overcrowded. If the fans bother you now, chances are they always will, so move them now!! There is really far more to consider than simply leaving the lighting plan to an electrician who often doesn't care a hoot if the lighting is adequate or ill positioned, unless you are lucky like me and have an electrician that does care, so if you want to make any changes whilst the wiring is going in, it's a piece of cake and don't let any electrician tell you otherwise!!!

Thanks once again oklouise for your comments. I have already been told by the draughtsman that I cannot put in skylights. No idea if this is true but he seemed quite sure and it was he who 'designed' the layout of said ensuite with what I consider a too small window because of ease of plumbing and drainage. He says that can be changed...............Supposedly only put like that to get the oversize plan in fir consent. This department is only interested in the outside view and the effect on the neighbours, which I actually dont have any. The positioning of the ensuite and WiR has changed too from the first plan as I had to come 'out' of my bedroom into a corridor past the WiR door and then into the ensuite. Technically they were both in my bedroom as had not entered the hallway but did not seem like it. So the wall you have now suggested for the door is a small lobby to the bedroom and I had planned to put furniture on it and a full length mirror. I will now look again at the whole space with three zones to see what can be done. I used the word solar tube as I thought that was the generic name for the 'tube' installed which reflected light into a room. Do they cause draughts? Have had no experience of them but will probably want to install one in my scullery (or Butler's kitchen) but am going to work in it a few months before deciding that. I am really quite a novice about function of installations and of building code.

Thanks Jeanne and Janet :) My kitchen is certainly earning its keep during lockdown here in Melbourne - excessive amounts of cooking and baking happening ;) The renovation was great practice for lockdown, with three of us confined to bedrooms and a makeshift kitchen for a few months while the house was dismantled around us.

The second look like they are designed for stairwells so I'd be a bit wary about using them up higher as the light might be a bit "spotlight" and not diffuse enough. I think both styles work with your house design
