Looks like they did a similar thing here with a false ceiling. These look a bit more built in as well.

Hello Marcelle, I am an interior designer . I can tell you a simple inexpensive way to change the look of your kitchen. Looking at the photo you sent the different cabinet heights , and all the objects on the stove wall are very busy . Your modern house is wanting a cleaner , simple look. I would lower the small cabinets so that the top is at the same height as the others in the room. And put doors on , that will hide the clutter. Next I would do a tile backsplash above the stove , up to the same height. The whole kitchen will be pulled together by the continuous top line. There is a small light wood cabinet with baskets in the foreground . I would paint it white , or the same dark accent color of the cabinets you have. I don't think you would need to change the beams then , they would add interest and drama once everything else was subdued. Lisa

I would balance the fridge cabinet wall by having the fridge centred between two narrower pantry cabinets as it currently feels far to heavy for your space. Alternatively, I would recommend having a narrow pantry on the left of the fridge with a full height cabinet with counter on the right with an upper cabinet above. This would help your space feel larger.

When you're doing lighting in a kitchen it's a good idea to have good directed light over the main tasks areas, cooking, dishwashing, food prep. You could achieve this with downlights directed at those areas, or track lighting where you can direct/angle each of the lights on the track. Re the pendant over sink area, would need to be at a height that ensures safety - water & electricity, not a good combo. There may be some NZ standards that you can refer to, to get the correct info.
