I'd be combining the kitchen and laundry by knocking out the wall between them and concealing the laundry appliances in the new kitchen. Ikea kitchen, nearly new appliances (someone is always selling a new appliance that doesn't fit) and flooring (the new linos look really good or perhaps a laminate floor?) If you had the budget, I'd also turn the bedroom next to the laundry into the dining room so your living area connects to the back deck with a lovely sliding door. Maybe also remove wall between laundry and bedroom to create open plan living? Not sure if this is possible if walls are load bearing, but steel beams can fix that maybe? Dining room then becomes bedroom. I like connecting living rooms to outdoor areas, but that's the Aussie in me. Good luck! P.s. Find a good carpenter who charges by the hour maybe? (I married mine!)

The kitchen will be custom built, I’ve put the voids in as I really dislike corner cabinets and blind corner cabinet units and would rather have more room for drawers. I spent quite a bit of time going through what I store in my current kitchen and I’m confident I’ll have enough storage even with the voids. Your question re the distance from the corners to the edges of the architrave... I think your referring to the sunroom door? I have 2160mm along wall A, this section is brick and the architraves are actually recessed a bit and sit at approx 2260. What other corner to architrave measurements do you need? We are having a gas cooktop, it is 650mm but will fit in a 600mm cabinet. As for the dishwasher i had considered moving it into the peninsula but we are building on a concrete slab and whilst not impossible the plumbing would be difficult here due to very hard to access spot under the house in this section ( enclosed/walled piers, low height). And I thought that having the dishwasher where it is allows for better access for two people in the kitchen, generally when we clean up someone deals with the dishes and the other person packs away leftovers etc. which will be best done from the peninsula where they can easily access the drawers under it and the fridge. Also my husband is left handed and I have been using a dishwasher to my left for the last 12 years so I‘m fine with it.

to access the power point through a backboard cut a matching hole in the backboard to access the power point and add a small extension cord to have the power in a more convenient location but storage depends on what you need to store but try the PAX wardrobe (1500 wide x 2100 high) with extra shelves plus a freestanding chest of drawers eg Malm 80 wide to leave a small gap at the window wall for the blinds and use wall hung open shelves and don't forget to secure the wardrobe and drawers to the wall...if you prefer the chest of drawers to be the same depth as the wardrobe you could add an extra counter on top of the drawers (Ikea and Bunnings sell custom cut counters in various colours but consider having the chest of drawers and/or the wall shelves in different colour for constrast and matching knobs or handles to doors and drawers

have you personally inspected the property to clarify the available space as the real estate photos show that bed 3 is already being used for the living area so the property is really only two bedrooms plus open plan living dining kitchen and attempting to add an upstairs powder room would mean having the toilet open into the kitchen living area ..it may be possible to install a tiny powder room above the stairs (say $10-$20,000... if you could gain Council approval to do it) but another property with an existing upstairs bathroom would be more comfortable for yourself as well as your guests
