My personal preference is for seamless hardwood throughout (except bathrooms), but it is just that--a personal preference. Many people prefer tile in their kitchen and hardwood floors through the rest of the house, or some other combination of floorings. Even though it seems like there are so many photographs on Houzz of seamless floors throughout, remember than whenever you are seeing a kitchen with a tile floor the chances are good that the rest of the house is not that same tile. So even though you aren't seeing the seams in the photos, many have them.

Hello Cody, If the TV isn't going on the mantle wall than the only other available wall is the 13'5" wall. You might think about moving the TV to this wall and balancing it with art or plants. Your sofa can be turned with its back to the entrance/stairs and a small console table can be placed behind it to act as a visual stop. Your chair can be placed where the sofa currently sits or you could add a pair of new chairs to this area near the stair alcove which would create a smaller seating cluster there. Small benches could be placed in front of the fire for additional seating, when and if necessary. This one is a challenge, but if you don't mind the TV as focal point and the sofa perpendicular to the fireplace, this could work. Best of luck with your decorating and please let us know if we can be of assistance, Elizabeth Cabell, ASID, CID Cabell Design Studio

Depending on budget, a glass guard that cascades past the dining room level would feel very modern. The attached image isn't the same condition but should give a good idea on the detail.

Hi Ibrahim29 Md, some ideas here. This home styled by Boconcept responded to the client's request to turn the living room into a reading corner: https://www.houzz.com.sg/projects/1385019/kate-jin-and-juliens-home and in this project, the service yard seems to harmonise well with the kitchen, even though divided by a screen: I'll leave it to the experts to give more comments!
