The bricks really warm it up. I could live there.

Lovely job, well done.

If you are in Sydney, we do have in house kitchen designers, who can help with kitchen layout and as your an electrician you can save money by fitting out the electrical side yourself, however we don't do landscaping. Have you had a look on houzz or pinterest to get some ideas of lighting you like. Ambience lighting is about having dimmers on your main lights and placing lamps ect in dark corners. Task lighting is important in the kitchen, office (if your having one) and basically anywhere you sit and have to look at things like a book, plans for your home, crafting, food. Sconces are to accentuate something like a window, painting or help you find your way down a hallway. Use long pendant, chandelier type lights for your ceilings it draws your eyes up. Track-lights or too many down-lights can look tacky. Everything essentially depends on how you are styling your home. A building company we have worked with that does what you need and are pretty good is Scopeview Projects. Check them out they maybe able to help.

I've added the room measurements to the post if that helps @oklouise. Appreciate your perspectives. Great to hear the thinner cabinets will work okay. Hi @Maree. Thanks for your comments! I'm using 5D planner for the design work. It's really easy to learn and work with in 2D and 3D. It has limitations in terms of the furniture styles and colours you can pick from, but it's so much easier than other options the trade-off is worth it. I tried to teach myself sketch-up but it was way too hard.
