What this model has
The gaps between the blocks are equal, so the row reads like a border strip, which is where the model takes its name. The repetition does a specific job: the eye doesn't settle on any one block but follows the vertical line they make together. A single large panel would have filled the same surface without giving it that movement.
The grey squares are the only second colour in the composition. Set beside the black blocks they stay small, so they work more as a rhythm marker than a stand-out accent.
The dark walnut ground sits close in tone to the black blocks. That closeness doesn't harden the pattern; from a distance the leaf reads as one piece, and the division only shows up on approach.

Frequently asked about this model
What gives Bordür its name?
The six black blocks run down the leaf with equal gaps between them, which makes the column read like a border strip rather than a set of separate shapes; that repeating border is where the name comes from. Each block carries a small grey square beside it, the only second colour in the design.
Does the walnut tone compete with the black blocks on Bordür?
No. The dark walnut sits close in tone to the black, and that closeness keeps the pattern from looking harsh. Seen from across a hallway the leaf reads as one surface; it's only on approach that the block-and-square division becomes clear.
Is Bordür available built to my own measurement?
Yes. The walnut tone, the black blocks and the grey squares stay exactly as designed; the leaf and door frame are reworked to your opening, with the row of blocks re-spaced so the border effect still runs the full height. We take the opening measurement on site before manufacture begins.
