Love those sliding door ovens – Neff is the company that produces them and must have one of the strongest patents ever, as no other company offers, and I am sure, would like to do so. I had my first eye-level, built in oven (not Neff), in 1972 and (except for the first year I moved to my last house), have always had those.
At present I do not have an oven. I have a lovely combi microwave, which also works as a convector Works extremely well as I have made bread, baked all sorts of cakes and pastry item, etc. etc. Obviously only for small amounts. Slow cooker does casseroles, etc. and I have a separate small counter-top grill (usually kept in a cupboard), as that is the only thing in that combi microwave which is not very effective.
IF….I have my kitchen re-vamped next year, will include an eye level oven (probably that Neff one), not so much for me to use (I will still keep the combi microwave which I will have built in above the oven), but looking at the future when my kids well be selling the flat after my decease. For the time being will, probably, largely use that oven for storing things!!
When I moved into my house in 2003 there was a long, galley kitchen and an under-the counter oven and grill. As, to use the grill, I had to keep the oven door open, it was a real hazard in a narrow kitchen. I had the so-called broom cupboard at the end of that kitchen turned into an oven housing unit.
The position of the oven should be suit you. Does not need to be at counter-top level. Assuming I have mine, it will be lower than that as I want to be able to use the space above it for the microwave.
Do not think that 90% quote is very accurate, Architects do not seem to like eye level oven unit and most new homes have the ovens under-the-counter – in order to give a long sleek look to the counter top. What with those and the large number of people who go for Ranges, think that the number of kitchens with eye level oven is more likely about 50% of kitchens. But so-called ‘designers’ are more likely just to be ‘Salesmen’ and not really know much about they say. Think that when buying (and positioning) an oven you also need to think if you want a separate grill/oven and also look at self-cleaning ovens. Position is important. When it is open (particularly if it has just the usual drop down door), it should not be in the way, so best at the end of a run…..and it is -good to have some work-top space right next to oven where hot items can be easily and safely placed.
