Gorgeous space. Feels like a table in that corner would obstruct the flow, forcing you to walk around the couch.

There's actually quite a bit of room in front of all the pieces - pretty large space. Here's looking that way

I'm feeling an iron structure. The coffee table in front of the couch is a good starting point, but perhaps with a glass top instead of wood. With the wood and stone throughout, iron and glass will bring in an accent in terms of both form and material, while maintaining the ancient material theme.

I'm coveting this space. I really hope somebody is sitting there strumming on a flat top tonight, because I sure would be.

I like this for your space. Hammered copper top side table. This one is pricey but you can find others for less.

HI -- Ok ,I am drooling over this house ! I like a lot of the little round tables at Restoration Hardware ... the 1930's Martini side table in antiqued brass --- the room needs the hit of rich metal . But there are many others you will like too . Just get round .
