What has happened to kitchens? Once we went to an island, it evolved into a single long counter in front of cabinetry. This looks great but real cooks need convenient appliance locations and ample countertops for assembling their dishes! If COVID accentuated anything, it was the need to eat from home! There have been more recipes published AND they have been more practical. So, back to kitchen design. From one island to two? How do you navigate two? Start with your appliance locations and go from there. Consider your preference for double ovens or a range. The spacing on this is a major determining factor. Restrictions also include doors and windows.
A recent photo I saw showed two islands and at the back was the Wolf range – between the islands. This range is a focal point and it is difficult to give it its due with an island covering it up!
Other designs show a prep kitchen separate from the show kitchen. Others have a spice kitchen for the separation of aromas! This is ever changing. Just work it out with function first as there are many options to make it look great!
