Since the lot you describe is smaller than my open living area, I would suggest looking at some of the "shotgun" house plans around New Orleans,LA. I think you can build up and back and get an interesting home with a loft for space. It can be done, A porch with an entry to a narrow hall at the back might work best for you. Will you plan a courtyard (closed)? or what? What part of the country are you in? What are your local codes?

Love the armless sofa-bench! Try using it in the center as a "cross-linking" piece between the sofa and chairs. That way people can sit on both sides of it, conversing with the sofa people and the chair people. Put the chairs where it is and use the side table from the left of the pic, or the one with flowers, between them. You'll need one huge rug to anchor the space or two smaller, and very similar ones, to put on either side of the blue sofa-bench. The other two side tables are too tall and too short for your seating pieces, so ditch them. Use your coffee table between the sofa and armless sofa (18" away from each of them.) Here's a chart for judging table and lamp heights as you'll need to work on that for balance. Please try this arrangement, and post by commenting and using the Attach Images button to add pix of the update. We'll tweak it on out from there.

Thank you Groveraxle for the virtual ! you are too good a designer that is why I cannot help troubling you ;) you have your biggest fan in me ever since your first advice:)) As for an in-house designer I am certainly going to call somebody soon . Just that I get such a lot of options and great advice from highly accomplished and talented Houzz designers ..I would be better prepared after these conversations ..please forgive me for pestering you guys like this:)

two basic issues your room floor is dull is that floor to floor carpet if yes then add a a smaller area rug under your table to get splash of colour, alternatively if you dont want to do that then add some colorful wallpaper behind the sofa. Where you have the table lamp add something taller like a modern floor lamp or a tall spread out palm plant. Take the table lamp and add to a side table if you have one. The second biggest issue is that you have a lovely modern sectional sofa and then you have paired it with a very traditional and very high coffee table that looks like it has marble inlay work done (cant make out clearly). This is not a good pairing. The coffee table is the right size but get something modern and a lot lower, a general guide to this would be one inch to 2 inches lower than the seating height of the sofa. As someone else mentioned an Ottoman that can serve as a coffee table in an alternate colour will also work. Paintings and wall art is something you can experiment with but unless you do something about the coffee table the room will continue to look odd in my opinion. Also some more shots of the room will help us get perspective.
