Hi Pazz, I really like your idea of seagrass wallpaper behind the bed, it would add texture and warmth plus make more of a feature of the window on that wall (compared with the other windows). If the wallpaper is dark enough, the concrete pendants would look great (but the cord will definately have to be jigged because you'll ruin the clean black rectangle of your window if the cord cuts it). I'm personally a fan of the Tom Dixon Beat pendant shape, and curved or rounded pendant would also soften the room which has lots of angular edges, plus it will throw wider light if the mouth is large enough! It's a lovely room, would love to see pic when you make your final selection! :-)

We did a kitchen very similar to yours and went thru a similar dilemma last year. Ended up with a large sculptural drum pendant with a diffuser in the centre of kitchen and led recessed spots above island. Spots and drum are on two separate control switches with both fitted with dimmers. Led can be harsh if not able to be dimmed. Plastic on our new dishwasher went from blue to yellow overnight on first day and we had to ask for dimmer. Led great as task lighting but postion them so your head doesn't block light as you work. We play with lighting depending on whether we are working or relaxing. Money we saved on three pendants was spent on one drum.

Depending on your taste of course, I would introduce some colour - either as tiles or a glass splashback. Personally I think you will need to fill the entire area otherwise there are simply more lines to take in and will create an unwanted feature. We've had a glass splashback painted back and it was super easy to clean. For one kitchen, we've gone for a bright yellow to give it some pop. You can also have photos too but it's not as easy as the file sizes mean that they need to be taken/supplied by a professional photographer. If tiles is your preference, there are many great patterned tiles out now. Good luck!

try www.soniclighting.com.au They're more commercial and specialised lighting consultant/supplier (as opposed to sales/shopfront) but they supply quality products and particularly good with the more contemporary looking gear.... if they don't have it visible online more often than not they can source something
