Embrace the arches and keep it light, but add some contrast. Paint every wall with an arch in it fresh white, all ceilings too. Paint the adjecent walls a soft color. For example; when you keep the kitchen tile, you could paint the walls above it a soft pink or mauve. I see three open areas, so you could divide those with three soft colors and white inbetween. Keep most lights simple and functional, uplights will enhance the arches, glass pendants will add warmth. And I think a soft olive or sage green is a great color for a living room.

It will be better if you don't think of separating it .

Send the measurement layout and the requirement details and we can work accordingly.

hello, well firstly, is it possible to change the location of the TV unit? if so...the living room can be easily moved near the main entrance and the dining area can be near the balcony. if not, as you rightly suggested, the dining table can be placed near the main entrance. depending on the overall interior style of your residence many room separators are available in the market or can even be customised as per your preferences (eg. hanging or floor screens, beaded Curtains, water wall, book shelf, vertical garden, blinds, stained glass partitions, wine holder dividers, shoji screens, photo display partition...the possibilities are endless). you also create some funky wooden distressed partitions like louvred screens. hope this helps. cheers!
