Great Portland Estates said it would not start main construction until a tenant had been secured for the 37-storey, 100 Bishopsgate tower.
Great Portland Estates, which is jointly developing the site with Brookfield’s property arm, said: “At 100 Bishopsgate enabling works are progressing well and are expected to be completed by July 2012.
“Construction of the 948,000 sq ft tower building will only be commenced once a suitable pre-let has been entered into and discussion with a number of potential occupiers are ongoing.”
The delay to construction is a second blow for Brookfield Multiplex.
The contractor was forced to suspend work for the second time earlier this year on the Pinnacle Tower project, just 100m away from the 100 Bishopsgate site.
Pinnacle developer Arab Investments is trying to secure the next stage of funding for the project, which is also dependent on finding an anchor tenant for the what will be the City’s tallest building.
At the time Brookfield Multiplex said the work suspension would allow it to redeploy its team to 100 Bishopsgate.
