First impression: I actually kind of love it! The mix of furniture styles, the different textures, the layering of patterns...these are all things I try to do in my designs. It gives a space dimension and makes it feel rich.
What would you change? I would definitely change the walls in the background. Because of all the wood, velvet, and brick in the space, it feels heavy. I think a fun, patterned wallpaper in lighter colors and maybe (dare I suggest it) painting the brick walls white would lighten things up.
What would you keep? So much! I love the mix of furniture, textures, and patterns. To me, it feels like a coffee shop. There's something nostalgic about it in that it is so different from our present-day coffee shops, which are designed more as co-working spaces. There's something about drinking coffee on an oversized velvet sofa that makes me long for the '90s.
Does it break any pillars of basic design? It's pretty good to me. It might be pushing a little bit towards being cluttered, but that's an easy fix...thinning out the knick-knacks on those bar shelves will make a huge difference. Remember people: we want a space to feel curated...not cluttered.
The verdict: Trash the clutter, lighten up the walls, and treat Gunther with a little respect, please.
