Hi all - I have a completely empty 17'x13'1" room that I would like to turn into my office AND a relaxing sitting room. The room has a beautiful bay window where a built-in bench or something else could nicely fit into. Here is the layout photo (sorry it's blurry):

The entrance is on the left, the window is at the bottom (here it is not shown as a bay window with a bump out, but it actually is). I love eco style (reclaimed wood) and industrial type furniture. Ideally would like some shelving too, maybe a built-in bookcase? Any ideas as to how I could decorate to make the most of this space and turn into into a multi-purpose room? Thanks very much!
