I will give you my opinion about sectionals . They are the most expensive way to buy the least number of comfy seats. Armrests = comfort so at best a sectional has 2 arm rests so the guys at the ends of the sectional are comfy and the rest are lined up on the dreaded middle cushion of a sofe no matter how big the sectional and if you get one with a chaise it is even worse sinc the chaise is not really useable for visiting.I like a sofa and 2 chairs 4 comfy seats and 5 in a pinch. I think a sectional in that space will be too big to get evne 5 seats at all.

Thank you for your input.  What size sofa do you suggest and where would you put the sofa and chairs?

I'd put the sofa facing the TV (back to dining room, assuming you're putting a table there), with chairs on the window side with a small table between. I think I'd go for backless stools so that you can push them under the counter when not in use, unless your counter is low enough that they could be used for extra seating when you have company (and the model seems to have a two-level couner) -- in fact, you may not have the depth to justify stools if there's just a tiny overhang, so wait to buy any. If you don't like the notion of a couch back facing out into the DR, put a narrow console table behind it.

Jan's correct about reversing the use of the spaces. I'd rather look out on the view through the window while dining. The TV watching area is better suited for the other area to reduce the glare from the window on the TV. But instead of a sectional I'd get a sofa for the wall facing the TV and 2 chairs on the other wall. Sectionals are more difficult to move and box you in to a layout, especially if you are considering moving to a new place. Sofas and chairs are more versatile.

I also agree to reversing the spaces. Try it out now with your existing furniture to get the feel for it.

Yes, reverse the spaces. It seems more logical to put the dining area next to the kitchen. Measure carefully, and twice or more, the space you have for the sectional and don't go over that when shopping, no matter how enticing it is.

I love the idea of reversing the spaces.   I think it is the only way to make the sectional work.   I especially appreciate the pictures since I am visual.   Thank you Houzz friends!
