Kitchen design apps??

So are you thinking the boxed mantle over the cooker section with a cupboard either side?. You have 900mm to the left of the aga and 800 to the right of the hob and oven, so they will look better with single cupboards rather than two doubles. Double cupboards start at 700mm width with me but most companies start with 800mm units and an 800 cupboard would feel tight to the door into the rest of the house.

I wouldn’t move the fridge freezer If it’s going to be an American fridge freezer as they are approx 760mm deep so would really stand out everywhere else in your room other in that little cut back. Standard tall fridge freezers and built in versions are only 600mm deep so you have more scope with them.

You don’t generally want tall cabinets on both sides though as that will narrow the width of the room and emphasise the length, you are currently a fat rectangle but This would become a thin rectangle and narrow the visual width of the room if you go tall On the left and right hand side. I Hope that makes sense.

Do you want a combi oven aswell as a single oven or instead of a single oven ?, if you have a look at something like a Neff C17MR02N0B that is a compact single oven 460mm cavity height instead of 600 and looks exactly like a small single oven inside and does everything a normal single oven can do but it also microwaves. When you use the microwave in it you don’t remove any of the metal as it’s been calibrated to be intune with the microwave. This is fine for 2 but you can only really cook on 1 shelf or 2 if they are thin. A combi could work on the island if you wanted, maybe backing onto the oven and aga.

Let me know your thoughts, I’ll tweak the mantle around the aga for you now.
