Most regions have their own prevailing construction methods and materials that are common and customary to that region. It may be driven by the available raw materials, local labor and their experience with a certain type of construction, and the cost of labor to build. Other factors that drive the different type of construction can be pressures from the environment and climate conditions. One can create recesses in masonry or stone walls but there may be structural weaknesses that become a factor or just more complicated construction that becomes involved. Building recesses in heavy masonry walls verses light stick framed walls can be equally possible. Reducing the thickness of a wall can also affect the insulation capabilities of that wall as well as the structure.

I like the ceiling. I think the hanging lights are too fancy and distract from the ceiling decor. A simpler light would look better or sticking with the canned lights you have. The walls have too many big, black things on them. It's hard to tell if they are windows with shade --- in which case I'd pick something lighter, perhaps to echo the ceiling, TVs (how many do you need?) or what. I'd consider a big piece of statement art in the place of at least one. If you're on a budget, get a large, high quality photo in the right colors, you can take it yourself. Sepia and black architectural might work. I like more color and more natural light. You may have closed the shades for a better picture, so it's hard to comment on the light, plus windows are a feature of your room, not exactly a decorator's choice. I would consider how to get a few small pops of color in, pillows, flowers, candles, maybe even a runner rug along the right wall. If you are doing this as part of a portfolio, the entire ensemble would look more welcoming with a few touches like someone lives there. Something on the coffee table, for example. A few books and a candle. A tray with tea things, a vase of flowers or basket of fruit. Pick one or two things and make it composed. You see this a lot in designer Houzz photos. Here's an example, you note this picture would be a lot more stark with an empty table: https://www.houzz.com/photos/21-house-contemporary-living-room-san-francisco-phvw-vp~60642

I personally would like to see you start your art collection. It may take a while but you will get there. And the hunt is tons of fun. Do not worry, about who made it, only that it is original or a signed numbered print of maybe 200 and that you love it. sources, etsy and Saatchiart. oodles and it changes all the time. often $100 or less. both under $60 etsy a few of the myriad ways to make your own Butterflies or some other small collectible natural or otherwise One large on subject matter, then small ones regarding that topic framed important things in your life magazines, album covers important newsprint that means something to you Bandanas, or how about the decorations off your favorite clothes before they go out. plates, or mugs, judgin by your couch, these are not it, but there are some really cool modern ones too large copies of musical scores. hope it helps
