Depending Regs, L would have both properties with double garages, parking is gold in Sydney, it would also make both driveways safer with better visuals. Th existing house is like small boxes, certainly doesn't need or have the space for a WIP, better to enlarge the living area this is a 4 bedroom house. The pantries could continue along the kitchen wall and would only need to be 300 - 400 deep for better storage and access without having to install draws for deeper 600 to work efficiently, also allows more floor space for the dining. 4 bedrooms with no Master? but a WIP?, I could live without either. The New build I would chaange so that it flows better, Kitchen and Alfresco together next to pool The Master with balcony, that space could be better used as a study, once again like the glass doors opening to the pool done with done with Juliet style glass across them, still have the feel of a balcony. Forgot to mark internal access from the new builds garage , they both should have that. good luck

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.

I understand the beam being installed when you did your earlier extension as that was an external wall, that's why I have suggested keeping part of the wall next to the island which was also an external wall, to support this, I will check this in the drawing to ensure it lines up for you. By opening up this wall as much as possible you are allowing more light back into the house The cost of running plumbing across I think is negative/comparable to moving the plumbing for the re positioned laundry and kitchen and removing any load bearing walls. Storage in the new kitchen is a big 2900 x 900 island of drawers for easy access, I have added a wall oven but that could become a 600 pantry with drawers in the lower part with a shelf above for small appliances. The wall with the TV could be a wall of narrow built in storage to be used in any way you need. This floor plan gives better flow between kitchen/family.dining/alfresco and better for unloading the car with the driveway running down beside the kitchen and verandah

By removing the upstand from the peninsula, and making into a full bench, this will dramatically improve the perception of more space. I notice the microwave is on the bench, because it will not fit in the space provided. I would work something out for your microwave, so it is off the bench, this will give you more bench space. The glass fronted Cabinets are wasting precious storage. Put solid doors on them, this will then give you space for storage. Or even a spot for the microwave. It appears that you have plenty of cupboards and a good size pantry. Why do you want to make it bigger. Do you have items that require storage?
