Do you have a plan of what it is now and which bits are being added? Or this already the footprint?
What is the line you've drawn where the pantry was? Additional kitchen units?
I prefer the shape of your main kitchen now. It's still not huge but you could be clever with that other space.
I have a fairly small kitchen joined onto a family room. It didn't work to have high units because of the way you enter in (it would have made it feel like a tunnel) and the windows, plus I needed work surface.
However there was room for a full run of low units in the family space. We opted for undercounter everything (all built in). It means we have two freezers just outside the kitchen and an additional fridge. We have an undercounter fridge which is the main one in the kitchen itself.
This works well as how often are you in the freezer? Once a day? I know some people hate bending down but this was the only solution that didn't ruin the look of the space and it doesn't bother us.
What I'm trying to say is if you do go for this slightly disjointed kitchen, think really carefully about what goes where. With the windows, pillar and corner you are also going to struggle for tall units in the main space. The fridge/freezer by the door might work but walking right round the corner every time you want a tea bag or mug will get annoying fast. For baking stuff, bulk supplies etc, much less of a problem.
Have a look at the DIY kitchens planner and play around with your space. Getting a kitchen layout you like seems key to unlocking this one.
