Welcome to another "Why use many words when few do trick" post.
Living room biggest room so must make nice. Went for spacious, playful, airy vibes. No false ceiling. Dark wood vinyl for calm effect.
Invest in a good sofa. 2nd best advice from mother-in-law. Space behind sofa for shelving. Wanted to build full height shelving but wallet says go modular.
Send ideas if have.
