Not a commonly used term in the UK, but such a useful addition to a kitchen. I don’t have one, but certainly would like one. It’s an overhead cupboard which extends down to the worktop surface to house appliances. My favourite style has a roll-top desk type of door and means that gadgets are hidden away but still easily brought out for use. I was reminded of these handy hidey-holes recently when I had a long chat with a lady needing a cupboard for her food processor etc. Clutter is an issue for lots of us and our cupboards on either side of the chimney breast are the nearest we have to the appliance garage, even having room for two vacuum cleaners as well as the bread machine (rarely used), the sandwich toaster (very rarely used), the Kenwood chef and my little hand mixer (both often used). So, air fryer? No. Car park FULL. 😉
