Like your space and choice of green. Like the green in the kitchen you referred us to. Looks a little darker or less yellow than one you did with Photoshop? You have the same issue as many of us, for one reason or another we end up trying to blend two disparate styles. The couches say man's room, formal, brown wood to me. Your room, kitchen and fireplace say much lighter in colors , style and spirit! If you try to blend the two you will end up with neither. Your purchases to go with the couches will just add to things pushing you in a direction you don't appear to want to go! I'd suggest you find some sofa covers, or even bed coverlets if you can't get covers to put over the couches. I like the colors in the fireplace. Please tell us more about what styles you like.

This is where the kitchen is going to be. Where my husband is will be counter top at that height. with a big wide counter top to sit under. on the back wall double door fridge a metre gap. 2 wall ovens then a sliding door where the ladder is. A scullery. Behind my husband to the side of him a sink the cooker then space. Where the big flat plank is on the ground (ish) will be the movable island. you can see a taster of the stone wall which will be on both sides of the entrance hallway, the flooring will look very similar to this http://carpetdiscounters.co.nz/product.aspx?product_id=441 . You may note the steel next to my husband on that side. it also needs to be treated. Thank you very much

Not keen on tiles ... prefer a smooth surface with no grout lines to try and keep clean

For a pass through window to be very useful, it needs a surface to place items that are being passed through, that can be easily reached from both sides, or you would need to coordinate people inside and out to pass things, which isn't feasible. I would consider whether it will be used as a pass through, given the door is immediately beside it. A small breakfast bar that uses the window for a view can also be useful for a pass-through set-down surface. Make sure the window is large enough to give a line of sight from person to person so that it is easy to communicate between the spaces - along the lines of 'Could you grab another beer?' or, 'I forgot the sauce.' I would also make the pass-through window a little wider if you do have a seating area, so it looks big enough to be welcoming, or it will be less likely to be used. At 2.500 deep, the deck is not large enough for a comfortable outdoor dining area of more than a couple of people. You need 600mm for comfortable seating on each side of a table, plus the table width which will be 900-1200, and with this layout, you also need another 900 mm to allow access past this, to the pass through, the seating and to the steps down, and with the deck being above ground level, space for access beyond the seating on both sides of the table is a good idea. If there is a barrier, you can get away without it because chairs won't fall off the edge, but it does make things tight. That adds up to at least 3000-3500 and preferably more. You can make things work with a tighter space, with a compromise to fixed seating along the edge, and a narrow table.
