Are you asking for furniture placement? Colors? Pics of your furniture and wall color would help.

what I really need is a layout of the furnitures, couches, tv panel, dining table etc

What pieces of furniture do you already have that you want to work with? And is that the kitchen on the left?

a couple lives

like to entertain

already have a breakfast nook, but need to fit a dining table in the living room]

an apartment

we like more of comtemporary

as far as the sofas- the best arrangement

the kitchen is on the left

the right wall- is all glass windows-half way up
