I believe the reason the tiles work well with the cabinetry is because the tile is lite in color and flat, its not rustic unlike most terracotta. The expensive cabinets work fine with the floors because of the smooth finish. The floor here is the focal point of this room. The Interior Designer or whoever did this room, did a very nice job, keeping it very simple.

A nice whitewash wall/paint treatment would brighten it up if done in a light color. Or I would paint it but not sure if all the knots will bleed through? If so then I would use an oil base Kilz to stop bleed through and paint it depending on the interior design I want for each room. I would not paint the ceiling for a more Montana look,

This is where the kitchen is going to be. Where my husband is will be counter top at that height. with a big wide counter top to sit under. on the back wall double door fridge a metre gap. 2 wall ovens then a sliding door where the ladder is. A scullery. Behind my husband to the side of him a sink the cooker then space. Where the big flat plank is on the ground (ish) will be the movable island. you can see a taster of the stone wall which will be on both sides of the entrance hallway, the flooring will look very similar to this http://carpetdiscounters.co.nz/product.aspx?product_id=441 . You may note the steel next to my husband on that side. it also needs to be treated. Thank you very much

Teal sounds beautiful for your splashback, I love vibrant and bright colours in the kitchen - you never see them enough! I think your worries are right as well, dark carpet and a dark bench would be too much darkness - a lighter benchtop would work well with the other colours! Marble is a classic for benchtops, but depending on how you did the wood, it wouldn't look fake at all! What did you decide on doing?
