While classic terrazzo is dotted with small fragments of stone, Alt Rock’s contemporary version uses sizeable slabs of statement marbles. ‘I wanted to develop an application for marble that can showcase the beauty of the material,’ says founder Robin Grasby. Made by hand in London, the designs use offcuts of stone, cast in concrete and bound with resin to create a surface that is not only hardwearing, stain resistant and waterproof, but also 90 per cent reclaimed or recycled. Use it for worktops, wallcoverings or bathroom surfaces. From £300 per square metre (altrocksurfaces.com).
