You have lovely pieces to work with. To my mind, it appears you have a long and a short MCM credenza/buffet. I'd prefer them switched and then move the art pieces so they take up no more than 75% of the credenza's length. Also keep them closer to the furniture and lower than the door and window frames if possible. Red is a wonderfully appetizing color and I'd love to see it on the dining room wall as well, although I know it may make the air unit more obvious. The dining wall is the one I'd fill with a bookcase for the cookbooks. As a one-time owner of nearly 100 cookbooks, I found they made for great dinner party conversation, along with an unabridged two-volume set of the English language dictionary. An IKEA bookcase could work well and hold plenty of books. The white shelf system with the red wall behind and the backs of the shelves painted red would look great! Or you can paint the bookcase red and leave the wall white. Group books by color for another touch of fun! Don't forget to show off some great "foodie" accessories too.

The all black kitchen looks scary as. Maybe because there's no lightness in there at all.

Here's a couple of ideas that work really well as alternatives to a walk in pantry. They integrate into your wall cabinetry, allowing you to keep central spaces open and free flowing. Using drawers to create a pantry as Esselai suggests. Check out how Harn Triomax soft close drawers are used in just this way. Availble in classic white or metallic grey. Two front to back depth options - 500mm and 5500mm. And 8 drawer width options from 450mm to 1200mm. Alternatively, there are a number of quality pull out pantry options in the German designed and made Vauth-Sagel range. Some are installed with fixed fronts to match your cabinetry, and others are installed behind hinged doors. See below (from top to bottom) the VSA model, DUSA model and HSA model. These all come in a variety of width options and specs, from chromed wire shelves to sold bases with glass panelling.

Thanks for your comments everyone. We've taken your advice (Luke and NH) and changed the island to a rectangle (1200 x 3000). We lose one breakfast bar seat but gain storage and dining room space plus it shortens the distances from the island to the cooktops. It also removes the need for a corner carousel. We're much happier with this result. Dairy_maid, we've done what you suggested and walked through some common tasks. Overall it works reasonably well although we may keep some coffee spoons and butter knives in the scullery drawers for morning toast and coffee. We've also invested in a "silent" rangehood which has the motor on the outside of the house behind the fridge and we've upgraded the scullery sink to one that is 600 x 400 (internal size). Fabrication starts tomorrow. Woohoo. Once again, thanks so much for taking the time to respond. The design has been significantly improved with your input.
