The contract for a new over station at Liverpool Street in the City of London has been awarded to Mace Construction.

Designed by designed by Eric Parry Architects, the new 1 Liverpool Street development is part of the Crossrail-led redevelopment of part of the station and will provide 176,000 sq ft of prime office and retail space, both on the ground floor and ten floors about it. The project is jointly funded by Aviva Investors and Allianz Real Estate and is expected to be completed in early 2026.

The scheme could lead to substantial orders for builders merchants in London as they provide the materials for the structure, which is to be built at a cost of £150 million. It is the second over-station project Mace is involved in, with teams currently on site working on the 101 Moorgate project.

A key feature of the new development will be its low-carbon credentials, which will include energy-efficient lighting, triple glazing and air source heat pumps.

Managing director for commercial offices at Mace Ged Simmonds said: “We are delighted to be working once again with Aviva and Allianz Real Estate on another ambitious project.”

He added that Mace’s commitment to sustainability means the firm is “particularly pleased with the high sustainability standards of one Liverpool Street, facilitating a move towards a lower-carbon  future.’’

While this Liverpool Street project has got the go-ahead, a row is continuing over wider redevelopment proposals for the station, which include plans for a 16-storey tower that opponents argue will spoil the Grade II* listed Andaz Hotel and Grade II listed station buildings.

The Liverpool Street Station Campaign, which has been reformed after previously battling redevelopment plans in the 1970s, has been vociferous in its campaign, arguing no listed building will be safe if the plans get the green light.

Head of the organisation, actor and comedian Griff Rhys Jones, said: “It’s not necessary to say the only way to deal with the station is to completely and utterly obliterate what you see of it from the outside and inside.”
