Right now there does not seem to be any symmetry on the path to your door. I would either eliminate the small trees that are there now, and replace them with bushes or shrubs that are equal in height and width, or cut these back and shape them dramatically, so that you have a clear vision to the door. Second, if you could change out the door, eliminating the side window, that's another idea. Sometimes just replacing your front door with one that is bold in color or style is enough to breathe some life into the front of the house. You could also either replace the concrete with pavers or paint the concrete with stain of a color that blends well with with nature.. like a lighter gray or a brown.

You can mirror sofas group . And place large tv on the wall center aligned. You can see it from dinning and living area

No chipped stone what would be the purpose of that ? Get a nice T.V stand depending on your style ( we have no clue ) then mount the TV at proper viewing height which is the center of the screen at eyellevel when you are seated . I love the Besta system from Ikea but it is very contemporary so when deciding on stand make sur eit is low to allow proper TV placement

Kramerlib, Is it just the window that gives away the privacy. How would sheer curtains or vinyls on the glass panes or reflective glasses work in your case.
