We need pictures of the space and a lot more info as to what is needed in the space for sure.

Ah, well, that's unfortunate. I was hoping precise measurements and a 3D view were enough. It's an empty room with studs and plywood at this stage. Yay fixer-upper!

You're not going to need a dining table in here? As always - measure twice, buy once! Have an overall plan before you buy or do anything. Measure to find the center of the window between the bookshelves. Put all seating pieces on furniture coasters, so you can move them around. Put a seven foot couch (or use your single love seat here) five feet away from center of window, facing window. Make sure the couch has thin arm rests. Place an oval coffee table in front of it. (I prefer two small coffee tables instead of one big one so I can move them around, but that's me.) Perpendicular to couch, on either side, place two round swivel chairs. Allow enough room to walk around. Place small round side table next to each chair, on the couch side of chairs. Add wall decor and floor plants/sculpture, if desired. Place accessories on side tables and coffee table. Regarding the approximately 4 1/2' by 8' area left over in front of kitchen, there are a few things you can do with that: craft table, dining table, reading area, mini office. Furniture placement is not permanent. Use your own needs and artistic talent to move them around as desired.
