You need a chippy. Look up carpenters in the directory. For an industrial look you can try painted steel ones from a hardware outlet, or stainless steel ones from an outdoor furniture and BBQ outlet, or outdoor kitchen fabricators.

A grey colour with a green undertone could work nicely... this way working with the green fencing and trims. sample pots are definitely a must so you can play with strength of grey and ensure correct undertone. If budget allows vertical cladding could transform the space further and create visual height...

If you are still looking at benchtop options you want to consider our QuantumSix+ 12mm porcelain sheets. Measuring 3200x1600mm so it is ideal for a seamless long bench or the 6mm porcelain for a splashback. The 12mm is available in 2 colours - white with grey vein or white with a gold/grey vein (marble look). 6mm is available in 8 colours from marble look to industrial grey.

while i can't comment on appliances with 6m of available space you should be able to spread out a little and make more serving space as well as making the size of cabinetry more streamlined...dividing the space into 4 x 1500 zones allows for 2 x 2 x 750 cabinets and fridge space or seating something like this with space beside the barbq for serving and stacking dirty dishes and i'm wondering if a dishwasher would live inside one of the cabinet spaces to make clean up even easier? btw your image is gorgeous and my poor 3d computer images can't compete..enjoy your new home
