privacy in a kitchen is nice, especially if you don't have enough storage..

But light from the big wall of windows might help with kitchen lighting.

and easy access to the outdoor living space... lots of options depending on the budget and needs.

Not enough photos or information to suggest remedy.

If you need more kitchen, you could extend your kitchen all the way in to the existing dining space and add a large island. nice an open living space for additional use.

Some inspro with bright and airy open-concept living space

What are your needs? What is your family size/age, or do you live alone? Do you have pets? Do you have people over frequently - casually or formally? Do you enjoy cooking?
