11 Million Dots
London's Largest Participatory Public Artwork
We are proud to have delivered the facade solution for 11 Million Dots. Europe’s largest participatory public artwork and a captivating fusion of art, technology, and community. Designed by London-based artist Rafael El Baz.

Sector: Data Centre
Location: Park Royal, NW10 6PH
Products: Kingspan HK-Design Cassette (Perforated)

The 2,700-square-foot installation transforms the six-storey facade of Vantage Data Centre in Park Royal, Northwest London, using our Kingspan HK-Design Hook-On Cassette Perforated panels
The ambitious artwork started with listening. His collection of audio recordings WERE the raw data – which were then digitally transformed into visual patterns – patterns that echo the shape of the clouds, the movement of trees, birdsong, conversations, traffic and machinery. Each of the 11 million dots resembles a sound from the environment, capturing the soul of the Park Royal neighbourhood. The audio recordings reflect the diversity of the area whereby each sound has a unique fingerprint or visual waveform.
“This Data Centre is designed to hold information, power and connection, but has become something much more for me and the Park Royal Community. Park Royal is one of the most hardworking and diverse communities in London. Families and communities have built their lives here.”
My practice is really about materiality, about sustainability, waste streams – the way in which we undervalue certain materials and how that leads into the way we undervalue certain stories. So, this takes the unheard stories of people and turns them into something sustainable.’ - Rafael El Baz
THE PERFORATION PROCESS
We developed and tested multiple perforation patterns using varied punch sizes, spacings, and orientations to best represent the artist’s image.
Smaller perforations were selected to achieve the required detail and contrast.
The artwork was divided into 9m x 3m sections to manage the complex geometry, with unique perforation patterns created for each.
Patterns were overlaid on elevation drawings, aligned across sections, and adjusted to remove holes in cassette shadow gaps and borders.
3D models and .DXF files were produced for CNC cutting and perforation, followed by CNC folding of each cassette.
Panels underwent inspection, stiffener welding, powder coating, and final quality checks before being packed and delivered to site.
