I like your idea. I just want to add that we get many posts here from people that try to add a large gray element to their space and then they can’t understand why it looks cold or “off”. Make sure a gray wall will work with the rest of your things. Wood floors, tan walls and brown furniture often don’t work well with gray. Depending on your space, staining the boards a light or medium brown might be a better choice.

Do you have any things you'd love to see every day? Do you like surfaces to stay pretty clean or do you like a lot of things on there? What are the colors you like? What kind of decor or other things do you find yourself drawn toward?

Which door is the front door? I think it would be nice if one door stood out as the front and the walkway went directly to that door.
