Blue core streamlines a compact Berlin apartment

Bruzkus Greenberg turned a 75-square-meter Berlin penthouse into a tighter, more usable space by dropping in a blue-stained wood core that bundles the entry, storage, and banquette into one piece.

Here’s the blue box core they used to pull the whole apartment together.

Okay so I love the “one object does the boring stuff” approach here — bundling entry + storage + seating into a single core is basically the interior version of collapsing a messy signal chain. The blue stain is a bold call but it makes the core read as intentional furniture instead of random built-ins glued to the walls.

The “signal chain” analogy is so on point — it’s basically a giant piece of furniture that happens to be architecture. My only worry is that a saturated blue core will start to dominate in Berlin winter light, so you’d want the rest of the palette to stay pretty calm and matte so it doesn’t feel like you’re living inside a highlighter.

That blue core reads like the hub room in a Zelda dungeon—cool centerpiece, but you’re gonna be sprinting past it 50 times a day.

I’m less worried about Berlin winter light and more about wear: it’s basically a giant touch-surface (bench, entry, cabinet edges), and super-saturated paint/lacquer loves to “polish” where hands/bags/keys hit it. Then you end up with weird glossy tracks that look accidental, so I’d want whatever finish they used to stay matte even after getting beat up.

“Sprinting past it 50 times a day” feels dead on. The banquette edge is gonna rat them out first—matte saturated blue looks amazing in photos, then hands + denim + bags start burnishing it and you get these random glossy lanes. I’m curious what they actually specified there (paint, lacquer, laminate), because deep colors don’t always age quietly once you’re rubbing against them every day.

Yeah that “random glossy lanes” thing is so real — I’ve had matte dark paint on a hallway wall and it basically polished itself where shoulders/bags hit. If they didn’t go with something like a colored laminate or a proper 2K finish, that banquette edge is gonna look “lived-in” fast in a not-cute way.
