(This story has been updated to include the number of homes at King's Cross Central.)
The King's Cross Central Limited Partnership has gained consent for a 54,000-square-foot office, Building F1, on the last plot of land that will be developed under the original consent for what has been one of the capital's largest and most successful developments of recent years.
The building will sit on an island plot at the giant development around St Pancras Station to form the southern corner of the intersection between York Way and Goods Way, along the Regent’s Canal.
The Lee + Wilkinson Architecture plans are for a six-storey, plus ground floor, office block, with a flexible shop at ground and first floors, and a self-contained office unit at ground floor.
It is the former petrol filling station site, which has had a number of meanwhile uses, as well as being used for the Gasholders London marketing suite.
The outline plans, listed building and conservation area consent applications were first approved for the Argent-led development in 2006.
Since then, reserved matters and detailed applications for around 8 million square feet and 12 hectares of public realm across the main site and Triangle site have been approved. Occupiers at the site, which has mainly been built, include Google, Meta and St Martin's College.
The development now has parks, houses, shops, offices, galleries, bars, restaurants, schools and a university on a former rundown industrial area.
In a LinkedIn posting celebrating the milestone, Robert Evans, partner at Argent and Related Argent, said: "There is a lot of comment in our industry at the moment, about the planning system, about why it is failing and how it needs to be reformed. From my perspective, the almost constant reform since King's Cross was first approved, has been part of the problem. The system is now in a bit of a mess, to put it mildly.
"But with the right people and the right attitudes, it is still capable of handling complex projects like King's Cross, helping to transform our cities and communities for the better and manage the transition to carbon net zero."
The King’s Cross Estate achieved carbon neutrality in 2021 and is let to major occupiers including AstraZeneca, Havas, Universal Music and The Office Group.
It is a 67-acre estate with 50 new and repurposed buildings, including the Gasholders London and the Granary Building.
When complete it will have 1,750 homes, a mix of private, rental and affordable housing, plus accommodation for 750 students. It is owned by the King’s Cross Central Limited Partnership, made up of pension fund AustralianSuper, clients of Federated Hermes and Argent investors. AustralianSuper owns a 71.5% stake.
