Building 1 on the site will be a 40-storey tower comprising five floors of 44,000 sq ft (4,100 m2) each and 32 office floors of between 19,000–25,000 sq ft (1,800–2,300 m2). Building 2 will be a seven-storey structure to be developed behind a retained façade, and will house restaurant and office floors of 8,000 sq ft (740 m2) each.
In May 2015, it was reported that building company T Clarke had agreed a revised contract 100 Bishopsgate, with on-site activities scheduled to start in April 2016. Ground engineering work began on the foundations to prepare the project for construction.
Planning and design
A planning application was submitted by Great Portland Estates in September 2006 for the redevelopment of a site located at 61 St. Mary Axe, 80-86 Bishopsgate, 88-90 Bishopsgate, 12-20 Camomile Street, 15-16 St. Helen's Place and 33-35 St. Mary Axe. The scheme proposes a mixed-used development comprising three buildings of 38, 16 and 6 storeys respectively. Where building 1 and 2 will be joined for 16 floors before reducing the core size of building 1 which will then continue to level 38.
The main tower (Building 1) would be formed of five podium floors, each of 44,000 sq ft (4,100 m2; 0.41 ha), and 32 tower floors, each of 19,000–25,000 sq ft (1,800–2,300 m2; 0.18–0.23 ha). The form of the lower part of the tower is designed to resolve the complex geometries of the site; thus the lower floors are shaped as parallelograms and the upper floors are shaped as rectangles.
The third building (Building 3) would be formed of six storeys of 8,000 square feet (740 m2) each, providing restaurant and office space.
A new public space of 0.5 acres (2,000 m2) is situated in the middle of the site.
The application was approved on 28 May 2008. In July 2011 the proposed height was increased by seven metres (23 ft) to 172 metres (564 ft).
Demolition of the buildings and infrastructure formerly on the site commenced in May 2011 and was completed later that year. The demolition work was complicated by the existence of six power substations on the site which needed to be kept operational until they could be bypassed. As of June 2016, 100 Bishopsgate’s core for Building 1 has risen to the 7th floor and steel columns are being placed. Building 3 both cores have reached the max 6 level height with steel beams up-to level 2 in place.
Ownership and tenants
The developer is The 100 Bishopsgate Partnership, a joint-venture between Brookfield Office Properties (87.5%) and Great Portland Estates (12.5%).
In April 2010 Brookfield paid £43m for a 50% stake in the project. In October 2012 Great Portland Estates sold 37.5% of its 50% interest to Brookfield for £47.2 million leaving it with a 12.5% interest.
