Aldersgate House sits directly above Barbican station, a late-1980s office building hemmed in by the Tube and Crossrail tunnels running beneath it. We are retrofitting it for UCG, an owner-occupier who buys for the long term and holds rather than sells. The constraints are unusual: the tunnels cap any added load at five per cent, which rules out extension, while the safety risk of working over live lines makes recladding unfeasible. So we work entirely within the existing shell, turning a tired, overlooked building into a set of boutique, low-carbon offices with a dual aspect, in one of the City's best-connected locations.

We strip out the suspended ceilings to expose the original steel frame, recovering around 300mm of height and bringing volume and light to floor plates that had little of either. The whole building moves to all-electric services, with air source heat pumps replacing gas boilers, lifting the rating from EPC F/G towards B. New ductwork runs beneath existing downstand steel beams, organised alongside lighting and pipework to maintain visual order in the exposed ceilings.
At ground level we double the width of the entrance lobby, absorbing a former coffee-shop bay and removing a cluttered canopy. Terrazzo, red travertine and timber line the arrival spaces, and the existing triangular stair becomes a marker, picked out in deep orange and lit so it reads from the street. Rather than fight the building's 1980s character of brick, precast concrete and Aztec columns, we lean into it.
