Do you have photos of this long column ?

Here are more pictures. Main door is exactly opposite the big opening. Forgive my ignorance, as I wasn't aware they are not called french windows. Since there is not much space between the main door and the big windows, I don't want to stuff it with furniture. Also, since we like big spaces, we would like to keep it as simple as possible. Anyway, my main concern right now is whether the bamboo blinds will work for these big windows, or they will give a stuffed look as soon one enters?

Potted plants and bench seating might work. You could put step stones with a ground cover that will spread in between. Your local nursery should be able to help you decide what would work best on something like that.

Waste of space IMO unless this becomes an awesome art gallery
