Astet Studio's reinvention of a building most Londoners knew as Nobu Hotel Shoreditch is the central act of Aethos London Shoreditch, which opened in 2025 as a 164-room boutique hotel and members' club. Ben Adams Architects' original 2017 structure announces itself from the street in board-marked concrete, bronze detailing, and cantilevered steel fins that step back from the cobbled lane in a stacked geometry more Brutalist in spirit than the brick-and-mortar neighbourhood surrounding it. The Barcelona-based practice Astet Studio, founded by Ala Zreigat and Oscar Engroba, was brought in to transform the interior and chose warmth as the corrective to all that raw structure: terracotta upholstery, oak panelling, and brushed metals soften the exposed concrete soffits without obscuring them. The lobby presents the clearest expression of Astet's approach, with terrazzo floors, a large paper pendant of unmistakable midcentury lineage, and a reception desk finished in veined stone pulling the eye toward a lounge dense with timber-panelled walls and amber-toned rugs. Guest rooms carry the palette upstairs: low-slung platform beds sit beneath bare concrete ceilings, parquet flooring introduces grain against plaster, and globe pendants on brass tracks provide the warmth that the architecture deliberately withholds. Throughout, the firm's narrative draws on Shoreditch's layered identity as a place where industrial discipline and craft sensibility have long coexisted, and the interiors make that argument without overstating it.
