WorldPay and Vanguard are closing in on taking a combined 127,551 sq ft at the Walbrook Building, EC4.
Credit card processing company WorldPay is understood to be under offer for 93,000 sq ft on floors five and six.
It has been in negotiations for the space since March.
Meanwhile fund manager Vanguard is understood to be under offer for the 34,551 sq ft first floor at the 331,805 sq ft office scheme.
The Walbrook Building has been on Vanguard’s shortlist since the end of 2012. It has also looked closely at the Shard, SE1, and Cannon Place, EC4.
Quoting rent at the Walbrook is £57.50 per sq ft.
The building was developed by Minerva, which was bought out by Jupiter Properties, the Delancey and Area Property Partners JV.
Jones Lang LaSalle and Knight Frank are letting agents on the building; JLL is representing Vanguard.
