The Jan issue of Real Homes has a feature on trends for 2016. Apparently the newest thing is a 'back' kitchen, where you can do, um, all that stuff that needs to be done in actual kitchens.
Here's a quote from the founder of Architect Your Home: "Kitchens have become an integral part of family/living/dining spaces and, as such, have had to become more stylish. While appliances are more elegant than ever, more functional designs can be hidden in a pantry or back kitchen... The danger in creating an extra room like this is that it could undermine the open-plan feel of the kitchen-diner. To avoid this, keep it simple in form and away from views through or out of the house, so as not to interfere with your main space."
Moving between two kitchens every time you cook is not going to be at all annoying, obviously. So I guess over time you do all your kitchen work in the back kitchen, leaving your front version an a very expensive accessory, a fantasy kitchen!
Own up, MNetters, has anybody got a back kitchen? 
Oh, the other trend is TWO islands - anyone gone that route?
