The layout of your new kitchen will depend on a number of factors, not least where the waste water from your sink, dishwasher and any other appliance that uses water, enters the drainage system. Moving any of these is not normally a problem but you may be restricted as to where certain appliances need to be positioned in the kitchen because of where the drains are. The usual method of planning a kitchen is to design the layout making sure you keep the distance between the key elements to a minimum. Having the food preparation area close to the sink, cooker and fridge will ensure you don't wear yourself out, running from one side of the room to the other. Without seeing the size and current layout of your kitchen, it is impossible to make any further, useful, suggestions. Choose your kitchen fitting company vary carefully and don't be shy in asking lots of questions, if they are any good, they should answer all your questions in detail. Hope this helps.

Firstly - the plan isn't the same as the perspectives... the plan actually appears to show Tall units around the angled bit, and two tall units in the corner to right of sink (which is cut into two cabinets) and then flows on with worktop over what appears to be a DW and WM (or pair of DW's ) this plan does seem to give more worktop space than the perspectives of the second plan. With any kitchen - but with an unusual shape kitchen especially - more info is usually required in order to create a kitchen that works in harmony with the rest of the home too - we often ask to see a 'right move ' type floor plan if there's one available ( as we design remotely/independently for clients - so wouldn't have seen the site ) if this is your long tern home - then I'd suggest you spending time with a designer either in person or with someone who offers a remote design service (like we do)

Thank you for all the comments! I really appreciate it. It’s great to have other inspiration to play around with. I’m not actually planning on using Wrens but their 3D virtual reality mock up is very useful! I spent the day playing around with different ideas, using cardboard in the space to mock things up, including tall units! The problem is the width of the kitchen isn’t huge so full depth units facing each other becomes a problem. I might have settled on a layout that wasn’t in my original sketches - I’m going to take it to a designer to see what they think. The only awkward bit about this design is there would be an appliance (probably the freezer) in the corner under the breakfast bar, so the only access would be from the lounge/dining side. My parents are wondering if I need the 300mm breakfast bar overhang, but I think that if I have units across the entrance to the kitchen like that, I’ll naturally want to use it as a breakfast bar and will be annoyed if it isn’t comfortable to sit at.. here’s my 3D app mock up of the space (not a professional mock up!!)

Because the tall units will be about 2.4m from the door I don’t think you have to worry about them being in your sight line…… but if you are worried you could of course put them on the opposite side of the room. However I always think that the usual 55cm chair seat height makes your eye line about kitchen cabinet height so you could feel a bit overshadowed by the kitchen island. In my opinion the solution is to put the kitchen at the dining end and then move the dining table towards the window. You might also consider dual purpose furniture- for instance instead of having a dining table and chairs plus a sitting area consider an upholstered dining bench that can be also be a daytime spot for coffee and reading the paper
