Thank you for posting the pic. Is it just open space opposite the chairs and a blank wall with the entry door? Any windows on that wall? Is that a table showing on the right of this pic, or a counter between living room and kitchen? My first thoughts are that those chairs must be pulled away from the wall and angled in some way, and somehow you need to find space for more seating. Could you angle them towards each other against the room divider, or is that a cupboard you need access to? Then you could turn the table 90 degrees, and place other seating facing the chairs. I'm liking the idea of picking up on colour from the green glass on the table, but I'm not sure how yet. I have a busy day ahead but I hope to check in later.

You need art on the wall and a rug and color! Your first step is to purchase an inspiration piece. That piece will either be a rug or a large piece of wall art. That sets the color palette for pillows chairs windows and walls. Wall color is last. Find out if you can have electricals inside the wall. I am guessing you are not in US and house is solid brick or this is a basement space as it looks quite industrial.

There are lots of nice cordless lamps. What if you take the picture to a store that just sells lighting, and see if they have something similar in their catalogs? It would be expensive but maybe worth it if you love having them be the first thing you see when you come in the door.

Why not paint it in a pastel colour? Add a carved chest that doubles up as shoe rack and organiser to store your shoes below and hold keys and bills in top drawers. You could hang a painting or a statement mirror above the chest and highlight with wall sconces or beautiful table lamps to shine a soft light around it.
