These panoramic pictures distort the appearance of the room. Better to post pics of the room that include all windows and doors to get a feeling for the actual size of the room and the restrictions.

A to scale floor plan is IMO the best way to get help for this type of dilemma. I agree distorted pics do not help. The plan is best done on graph paper showing all windows doorways where the doorways lead all measurements clearly marked and how many seats at the dining table and what you need in the office .

How do you actually want to use this space? Do you want it to be a dining room? Or an office? If it's a dining room, you'll want a table in the middle of the room, not against a wall. If it's an office, you could put a desk or table against the wall, but you could also float it in the middle of the room so that you can look out the window while you sit at the desk.

Make sure you think about traffic patterns and walkway spaces. As mentioned, it would be helpful to see a floor plan, but I'm guessing you might have taken the picture from the kitchen. If that's the case, you want to make sure there's plenty of room to get in and out of that room.

As Patricia says, we don't have enough information to make really informed comments, but it did occur to me that if you put in a built-in on the solid wall (the one without a window or door) that was a desk (and maybe also some bookshelves) but had doors that could be closed to disguise the face that it is a desk when it wasn't in use that you could make this room work for both purposes. It depends on how big the room actually is, how big a table you want, and how much work space you need.
