Since July 2024, the Kabinett floor has been fitted with a Byzantine-style mosaic made from marble, granite, and found objects. The marble was sourced from local South London marble yards Prestige Marble and Marble City.

The found objects were collected while mudlarking on the bank of the River Thames. These objects include: shells, tile shards, and weathered pipe stems that have been tumbled and softened on the riverbed for up to 100 years.

The former floor of the Kabinett had rotted through. To conserve the floor, a waterproof, silicone-based sealer was applied and a new concrete layer was poured.

The mosaic was produced offsite using the double reverse, aka Ravenna method, routinely used by traditional Italian mosaic practitioners to ensure that mosaic floors are as flat as possible. By creating the work offsite, the artisan is able to take their time, developing the design and implementation without facing external factors that are present in situ. After completion, the bottom of the mosaic is adhered to netting, cut into sections, transported to the site, installed, and finally grouted.
