I would clad it in horizontal wide timber flooring planks. Myself I'd go a grey, weathered timber like an oak, the engineered flooring can be bout in packs, so a single pack would create a feature inexpenssively. It will provide the oppotunity to introduce timber details in furnishings or kitchen accessories. Natural timber softens modern interiors, relaxes and adds character to traditional looks like provincial or hamptons styles. The wide plank will enhance the flow as a walk through, but still provide an intersting visual texture to the adjoining lounge area.

A good rule of thumb is 1m from table to a wall, to allow room for the chair to go back when the person is seated without feeling too crowded. For a thoroughfare behind a chair I would allow 1.2 - 1.5 from table to bench, the more the better.

This is a houzz picture with similar location of fridge and island.

Hi Mark, You might also check out kitchen design considerations in the Liveable Housing Design Guidelines They suggest for Gold Level that: (A) The kitchen space should be designed to support ease of movement and adaptation with: at least 1200 mm clearance in front of fixed benches and appliances (excluding handles); and slip resistant flooring. (B) Floor finishes should extend under kitchen cabinetry to enable cupboards to be removed without affecting the flooring. Where fixtures cannot be easily removed (e.g. ovens which are built in) the floor finishes should not be continued. And for Platinum (highest) Level that: As for the gold level except that the kitchen space described in (A) should be designed to support ease of movement and adaptation with: at least 1550 mm clearance in front of fixed benches and appliances (excluding handles); slip resistant flooring; and task lighting installed above work spaces. These standards are being considered for incorporation into the National Construction Code (BCA). They will not appear for a few years yet, but by considering and incorporating these principles now it may future-proof the house to some extent.
