A new core has been introduced to connect the residential spaces with the offices below, which also allows the floorplate to be split into multiple occupiers.
Brickwork and stone detailing has been repaired and refurbished, while the original Crittal windows has been replaced with modern equivalents. A new light well draws light through the building down to the lower levels.
