To turn a windowless room into a kitchen? Or should I add a window?

[OrangeCrushes]

We are converting a reception room into a kitchen. The room has doors into a conservatory but no windows.

Photo of room attached. The window would go to the right of the chimney breast, where there are currently shelves.

Due to the narrow size of the room, we will have very limited wall space for units. I'm very torn between a desire for natural light and ventilation v. more useful kitchen space.

YABU = Add a window!
YANBU = cupboard space is priceless

We will follow all applicable rules!

When I moved in to my house, it had a conservatory on the back of the kitchen and then a doorless wall to another room that had a window which was used as a utility room.
I took the wall out and it was the best thing I did to let the light in to the kitchen. I just remember being able to look out at the garden when in the kitchen do something as boring as washing up.
I don't think it's a deal breaker as the house had people living there before and they were fine it just wasn't for me.
What I did do though was put a proper roof on the conservatory to make it more usable which means that the door is open alot (most of the time) and the light shines through even more.

If you have played with the ikea kitchen planner then you know they..and lots of other companies do shallow depth cupboards. You could have a whole wall of storage behind those stools.
You wouldnt have every cupboard accessible if people were sat. But thats not really needed for a lot of kitchen equipment. But nor is the depth.
Otherwise, that creeping worry you have is absolutely right. You do not have enough storage.

But all we need in the kitchen is day-to-day storage. The utility will be a larder and pan overflow area as well!

We don't have an external door in our kitchen, but we do have three large sash windows. When they are fully open there is a huge amount of fresh air coming through
