Hi Ni, I just thought of something....did you say you planned to do the stencil motifs on the window wall? If so, I am thinking they will be mostly hidden by the curtains. I wonder if it might be better to stencil the long wall that is on the right side of the room when looking toward the window. I could see this being a pretty backdrop to the prayer box (I think that’s what you called it?) and your wood cuttings. Then maybe the opposite wall (the one with the kitchen doorway) could hold a large piece of art?

I would take away those top arches and have builtins either side of fireplace, have the tv placed on a shelf on the built in, like in the pics, you don't have to have it above the fireplace, if room is small it will feel like it's coming at you lol. Panel above fireplace and hang some artwork or a nice mirror. Quiet like the builtins with the back wall painted

Looks lovely - really like how the colours of the cushions tie in with the painted leaves!

I would suggest you to cover some part or whole of the terrace floor with artificial grass. It stays green all year round and is also very easy to maintain as compared to natural grass. However, leave the place where you plan to install BBQ basin as it may get damaged because of fire. You can even place a swinger and 1 or 2 garden table set.
