For the Keller Minimal Windows presentation at BAU 2025, once again an 11 × 8 m area was utilised – though with a reimagined spatial concept that positions the brand with even greater precision and confidence. The architecture continues to draw on the radical transparency and technical elegance of the products, yet introduces a darker, more focused aesthetic that showcases the exhibits as if in a high-end gallery.

The exterior structure now reads as more monolithic: A clearly framed volume with expansive, near-invisible window facades that offer views into a fully controlled interior staging. The dark, matte surfaces create an elegant visual weight that effectively contrasts the light, filigree quality of the window profiles. This interplay between solidity and transparency translates the brand's aesthetic philosophy into architectural form.

At the heart of the interior, an iconic ceiling element – a cube in brass finish – takes centre stage. It functions not only as a light installation but also as an identity-defining feature that subtly references the brand's formal language. The ceiling fins create a linear sense of depth and zone the space without compromising its openness. Black furniture volumes, precisely positioned light accents, and surfaces of glass and metal establish a calm, highly focused atmosphere.
