Samantha B I just completed my kitchen Reno in Perth. My pantry was also bricked up like yours. Literally doubled the space by getting rid of it but we found out after that the pantry was structural & we had to put an extra support beam in the roof instead ($800) so be careful of that! We completely moved the plumbing, gas & electrics & it only cost a few hundred! So don't be afraid to do that as long as u know decent priced tradies! We ended up doing nearly everything ourselves & went with a masters flat packed kitchen & sourced our own stone benchtops dirt cheap ($2500 installed for a 2m bench & a 1.5m island each with one waterfall edge.). Heres before & after pics.

You have a lovely young family they only get bigger. I'ts a shame that you can't find another position for the TV as it would be good to be able to see it from the Kitchen via your peninsular, so as to keep an eye on what the kids are watching especially as they get a bit bigger. I'am feeling a bit over the WIP and the idea of walking into a small often dark space, I really like the narrow hidden pantry (Running parallel behind the kitchen). I also like the full length pantries that can be shallow or with draws to make it easy to find things, with either sliding or opening doors. What height is the wall between the new dining and kitchen

Could you swap the fridge with the wall oven, going by your photo both fridge and Wall Oven would fit side by side. I would definately have the fridge on the cook top wall and not on the other side of the kitchen. I see by the photo that the timber beam could be in the way, I would speak to your plumber who should have a simple solution on ducting the range hood. A simple one built into a special cabinet above the cooktop can recirculate or be ducted outside by either exposed stainless tube for your industrial/country look or have the ducting boxed in, the ducting can be flexable so no problem avoiding beams.

Thank you everyone for your responses. I’m still undecided - I have a few weeks to consider what to do. The bench top salesperson showed me some photos of the few people who have added a small amount of benchtop stone to add some height (and it’s always because of a busy 60 x 30 patterned tile that the owners want to keep perfect) and in her words it looks ‘dicky’. Not least because the tile sits flatter against the wall than a 2cm thick slab of benchtop. It leaves a pronounced lip of 1.5cm where tile meets benchtop addition Then there’s the safety concerns mentioned above about flames near stone which I had not considered. Big reader - I love your maths but I’m only 150cm tall. Even with a low bench and oven height of 94cm (my oven’s lowest height setting) plus 70cm of tile between the bench and overheads, the cupboards are already 14cm above my head. This barely makes them usable for me even now! Adding another 15cm instead of the 10cm, while looking lovely and keeping the pattern intact, means my short-arse self will have real difficulty reaching anything safely. Every cm counts when you’re short! But I do appreciate your input!
