It's so hard to have an open concept and a wall for a tv. If this were my house, I'd think about having the room currently marked "DR" as the family room. This way, you would have some wall space. Another advantage of this set up is that your formal space, LR /DR are together and your casual space, FR, rooftop deck, office, basement are on the other.

I think you need to think about how you want to use the space everyday. How do you intend to use the sunroom? Does it need to be a separate Segregated room from the family room or kitchen, or can it be incorporated differently? Do you grill on the rooftop deck? If so, it might be nice to have the dining right there as shown. Is your rooftop deck used seasonally? Do you have children that need to be supervised when on rooftop? If so, you might not use deck as often.

Could you move the rooftop deck door to the right so that it's in a walkway and you don't need to walk around furniture to access the door? I would consider a door with half glass. I guess this is complicated if you want to add a step up to door. Could the deck immediately outside the door accommodate a step up to deck on outside rather than inside?

If not and the interior step up must remain, I might consider moving the door to the right and put a fireplace on the left of the door with a step up stone hearth that extends to act as the step for the deck. But if you are in warm climate, I guess that won't work.

You new home is lovely. Such nice character.

Four square homes were never built as open concept. The name "four square" means 4 rooms over 4 rooms. The last thing i would worry about is where to position a tv if a structural engineer hasn't been engaged to make sure the house doesn't collapse with your knocking out the interior walls.

@ jmc01 - I think the home may be a foursquare but I am not really sure if it is or not. If you read the articles above you would know I did not just go knocking out walls. I did not knock anything out that was structural. I did consult an engineer and a contractor. I would not do something so foolish that could cause the house to collapse especially since in these old homes sometimes the what holds the house up goes from basement all the way through the attic. Thank you for your input I appreciate the feedback.

@ dily - Thank you for the ideas. I really like them. I like your idea for moving the door to the rooftop deck over. A glass door is what I wanted. I never thought of the fireplace on that wall, but that is a GREAT idea! And the idea for the step up hearth is a FANTASTIC IDEA! I can't wait til the contractor comes cause I am definitely gonna find out if this can be done, I sure hope it can!

The Rooftop deck door is just a couple inches up from the deck so I wish we could move the door down, but that would be too costly to do cause it would involve too much structural work.

The Rooftop deck is only used seasonally and later we do plan on grilling out there.

I do not think the Sunroom has to be segregated, but if I open the kitchen all the way then I will not have any Sunroom you would be walking in the side door through the Kitchen. That's why I am debating about the small addition, but that would depend on the cost factor also. We have a lot of renovations to do in the house and I will not be able to do them all at once, but with a plan in place I can tackle each renovation 1 at a time.

And I'm guessing you are thinking keeping the living room as a living room?
