A small sink would fit in the second floor plan w/c. its 2.8mx 1.4m so definitely enough room. If we use the last floor plan with separate w/c then it opens up the bathroom to be 2.7mx 3.2m which for New Zealand standards is a big bathroom for a shower, bath and vanity. I'm still trying to decide if the space for the dining and kitchen areas are big enough?

The second one just looks a bit odd to me. I think it's because the wine is on display whereas the first wine cellar has all of it hidden away nicely.

A very simple layout keeping the floor space within the kitchen, the WIP takes up a lot of space with not much gain, The broom cupboard could be moved to the Laundry/entrance, narrow. If the wall has been bumped out to the eaves on the deck side giving an extra 300 depth to the kitchen you could make the island 2700 x 1200 and all drawers. The wall of narrow pantry will hold all pantry needs and more, no deep cupboards to dig into. cheers

Um why ? I'd do a coffee table , and have the light maybe 1 metre or less from the ceiling . The second one I'd just balance the first one , so if the first one is say 2.5 metres from one wall , hang the other 2.5 metres from another wall . The lights are really nice -- you would want them to be seen , rather than highlighting a couch IMO .
