I like it as you have it. Light filled, and uncomplicated. Nice space!

Whenever you have the outdoors to look onto, then it's like he best art work in the world. No curtains. But . . . move your grill and other covered deck item to the middle of the deck for the winter so you don't have to look out at those dark shapes.

Just wanted to add that you've created a beautiful space--simple, warm, inviting. Your space really works.

I’m usually a fan of curtains and think many rooms look incomplete without but I truly like yours as is. Very nice.

The room has great light coming through! Does not necessarily need curtains to dress it up, but the first comment was a great idea! The doors do not need curtains, however the arched window would look great with curtains placed higher than the arch (but almost reaching the floor) to lift the eyes and make the room seem bigger. Keep the curtains on either side (not drawn) to make the window look even bigger than it is!
