Hi Susan, you need to post a room plan with dimensions if possible.

I did thrice but don't know why it disppears

That is one tiny floorplan (it shows up tiny on my laptop). What do the measurements say? Where is the current kitchen? Plumbing? Where are the doors and windows along the walls?

You need to post the dimensions of everything, the doors, all the walls, the width of the utility / W.C etc..............However, the room is too small for a kitchen, Island and dining area.

You could run the kitchen down the right hand side, but as you see, the island doesn't fit even if you made it only 60cm wide.

You could have a kitchen with an island like this:-

You would be better off with something like this:-

Sorry about that. Its actually a 4.4 *6.6 m room where I need to put in a w/c, kitchen and dining area.

I have marked the existing doors, everything else is undecided at the moment.

The top is the extension and bottom is existing dining. The space where the wc is shown is my current kitchen

Sizes?

Both are 3.3* 4.4

I think your space is not suitable for an island, as in: it won't add anything.

Not knowing if plumbing would allow I made this:

Is that layout done on 6.6* 4.4 m? All plumbing is to the wall of the garage. Is that a utility room on one side?

Yes 6.6x4.4m. And a utility, about 1.3x1.6m internally.

Could garage door and living door be moved?

An island like this would mean your table would have to go in the 'traffic area'.

Moving the livingroom door might solve some of this.

Let's say your garage door can be moved. Utility with door on the 'side' and toilet in the back.

Kitchen layout might be less ideal when you had an island in mind, but on the bright side, the extension is big enough for christmas/family dinners!
