We're finally sorting out a kitchen extension after 7 years of living with a crappy brown, drafty bodged job. I am excited! 
It's about 6m long by 5 wide. West facing. The utility shown is really kljust a cupboard for the washing machine/dryer because I'd like to have them a bit out of the way.
How should we lay out the kitchen? Is a long run plus an island the best approach? Should we put the hob (or sink?) on the island? What do I need to think about?
I don't want seating on island, and we are not a tidy family. I'd like it to be possible for one person to make a cuppa while someone else cooks with getting in the way too much.
