You need to name the spaces and if you want help here this is a US site so all feet and inches for the measurements Maybe what is the orignal floor plan too

There is no space to manage really. The space between kitchen and living is walking area.

This was just a proposal. What I was looking for was ideas beyond the want those. Like putting the sofa in another position maybe? Or choose a sofa smaller?

Thanks!

What are you doing in this project? Designing a home or placing furniture? Is this a renovation or new build or is it built as is and you want to furnish it. Personally I would never by a curved sectional. I think they are very outdated.

I would choose a shorter sofa, not a sectional. Is the window area behind the sofa a sliding glass door or French doors? There is a traffic pattern there and unless you change the configuration of the opening you are stuck. If you're working with existing windows, can you show us a picture of that wall? Maybe you could change the opening to have a fixed pane of glass on the right and a glass door on the left side?

No dining area? Will you always sit at the counter even when entering?
