Hi anna_cannon, having a plan drawn is a good start, you might want to put the dimension on the plan as well just to help others know exactly where everything is. This is what I think works given the information I have. Not sure if you how much renovation you are looking at and whether you need both doors to the back but I kept them just in case. Basically I have grouped similar functions together such as (freezer, pantry) (linen, washer/dryer, sink), and (bench, coat hanging close to the doors in the back) ... all the plumbing stays the same to keep cost down. Hope this gives you an idea on what's possible in your multi-functional space.

Thanks :) All very good points. We thought about having the cabinet doors put in for the fridge but we personally haven't found them to be too practical in the past. Ones we've used haven't seemed to seal so well. We are also planning to upgrade the fridge in the next couple if years. Good thinking about placement of the microwave too. We have a power pack range built into the wall cabinets so unfortunately we can't put the microwave above the cooktop. I like the idea of the appliance cupboard being turned into a corner cupboard, although I'm unsure if that would mean that you then couldn't easily access it from the other side of the bench..? I'm hoping our kids will sit at the breakfast bar and make their own toast etc while keeping out of the kitchen itself.... I also wonder if we should have the wall cabinets all in the same line or if we could drop the usable ones, on either side of the power pack, down further to give us more storage....? And (I promise this is my last dilemma!) does anyone have any ideas on whether to place the 1/4 sink to the left or the right of the main sink? Again it's one of those things that I'm going around in circles about....next to the prep area vs next to the dishwasher.....? ...... Ahhhh decisions, decisions ;-) Thanks again

Unless buying custom manufactured wood cabinets, you are buying a series of boxes. A 100k euro kitchen installation of an Italian kitchen is one example from my portfolio. Differences are found in the hardware, the door/drawer pulls, weight of doors and exterior finishes. It is about the design, first. In our region, you can knock off 1200-2000 just be sticking with a full depth fridge--but it is design that will make it possible to install full depth and get a counter depth effect. In the Garden Oaks Fine Accommodation residential display suite I needed to prove that a high-end design can be executed for less. Again, it is design that does the trick. The owner of the kitchen above loves the pendants over the breakfast counter. I did not have the heart to reveal the price--$19 each. That owner likes/needs bling so the 14k euro chandeliers (2) in the foyer are a feature. But we get more comments on our pendants--because they are integral to the overall design. Real estate agents have pegged this kitchen at anywhere from 45-75k. It cost under 30k. DYI projects offer the opportunity to take the time that you might not otherwise allow to a designer (hence our need to come equipped with knowledge, contacts and suppliers that augment our services). I recommend drawing from images (Houzz is great for that) to start, then researching suppliers, collecting specs, and developing a document that covers all aspects of the kitchen from lifestyle needs to style to comparisons of product reviews. Whittle it down to an instruction for purchase and installation. Consider challenges such as the dreadful corner cabinet turntable and splurge on solutions that make your design truly functional. You'll appreciate the expense that delivers practical functionality. There are remarkable solutions for the corner cabinet--but my fav is to determine whether that space can become storage (cabinet or drawers) in an adjoining room. When not practical, articulated pull-out stainless shelves are functional--and cool. Undermounted sinks are great for clean-line counters. Well placed recessed lighting (design again) eliminates the need for other fixtures--and allows you free rein to purchase for focal point impact or (my preference) to fit seamlesly into the overall look. Enjoy the journey--have fun!
