KPF’s on-off Pinnacle tower scheme is back on again after the developer said construction work would start at the end of this month.

Arab Investments first appointed builder Brookfield to construct the City of London’s tallest building back in summer 2007. But since then it has been hit by a series of funding issues which has meant work on the 64-storey structure has only got up to ground level.

KPF has since included plans for a viewing gallery at the top of the tower in Bishopsgate.

Asset management company Schroders is one firm being linked with a move to the tower with the building due to be completed in time to meet an anticipated shortage of office space in the Square Mile between 2012 and 2014.
