Thanks kerrydonn and minnie 101 for getting back to me with your comments. I thought it was going to be a struggle to have this new room as kitchen, diner and family area too which is why I thought I'd see what others have to say. The extension we are having is only 3m x 5m as the other 2m is coming from half of an existing dining room and kitchen to make the whole area 5 x 5. At the moment we have a massive dining room and fairly large kitchen but they are separate and if we knock through we just end up with the 2 rooms, plus utility & cloakroom downstairs, and that just wouldn't be big enough. So the plan is to split the last 3rd of the dining room and kitchen off and use that together with the new extension to make one big room. The part of the dining room left will become a spare bedroom and ensuit and the part of the kitchen left will be corridor with a big boot room/storage. It was have lots of cupboards and storage and as it leads into what will be the new extension it can house a fair amount of kitchen stuff too, along with coats, shoes, hoovers, mop - all that stuff you never have anywhere for it to go. I guess we'll just have to wait and see to make final decisions once the structure starts to come together. Bye for now.

sorry hbutchart I missed your post. rubber flooring could be a good idea from a safety wet area point of view but it could look a little 'commercial' but again the right product and colour can look great. I would also check how this type of flooring would work with underfloor heating. If you sont use rubber either ceramic tiles or vinyl tiles would be perfect the vinyl tiles come in many styles concrete, slate and wood effects habe a look at Expona on line its a great product.

If you use a 1.2m sliding shower door and tray fitted into top right - you could then slip in a small hanging space for coats to the left side.

I like the pull out cupboards, excellent idea. At only 700mm wide, lets face it, you can't go in, so Jen is right the depth makes it awkward. Quite often those cupboards are near to kitchens and bathrooms, and are made that deep so that you can put a washing machine and tumble dryer in one on top of the other, plus have space in front for the washing machine door to open. They're ideal Utility cupboards for people that want to free up space in a kitchen. However, they're great storage if you can figure it out.
