22 Bishopsgate

The architects of The Pinnacle were Kohn Pedersen Fox and the developer was the fund management company Union Investment. The height of the tower was initially proposed at , but this was scaled down to following concerns from the Civil Aviation Authority. The revised design included approximately of office space. The Bishopsgate Tower, as it was first called, was submitted for planning permission in June 2005 and approved in April 2006. The twisting design of its roof and the curling patterns in the façade were based on various organic forms in nature such as armadillos, mushrooms and seashells, and led to the building being nicknamed "The Helter Skelter". The upper floors were to contain restaurants and the highest public viewing platform in the UK. The Pinnacle's original design also provided more solar panelling than any other building in the country, with of photovoltaic cells, capable of generating up to 200 kW of electricity. It would also have had a double-layered skin like the nearby gherkin-shaped 30 St Mary Axe, allowing it to respond dynamically to climatic changes and to utilise effective climate control with low energy consumption. To control construction costs, every panel on the tower would be of exactly the same size. In August 2006 Keltbray began test-piling on site. Demolition began on the smaller of the two existing buildings in November 2006. In February 2007 it was reported that the Bishopsgate Tower had been purchased by Arab Investments, and that the structure would be renamed as The Pinnacle. In May 2007 it was announced that full funding had been secured and that The Pinnacle was likely to be built speculatively. In June 2007 demolition began on Crosby Court, the larger of the two existing buildings on the site. ==Sustainability==

22 Bishopsgate's environmental, social, and governance policy, ESG, states that the building was envisioned to be engineered for optimum sustainability. The building management has goals to limit waste and energy use within the large structure, including care in what they purchase as the building is occupied by tenants: "The 22 Team work to a set of circular economy principles and innovative logistics, built to reduce waste and make the smallest impact possible on the spaces around us." ==Demolition of previous buildings==

, was once the headquarters of Standard Chartered. Demolition of the existing site began in mid-2007. It was scheduled to be completed by February 2008, however this was delayed until April 2008 because of an injunction won in December 2007 by Hiscox, an insurance company based in neighbouring Great St. Helen's. The company complained about noise pollution from the work. The injunction obtained by Hiscox Syndicates & Another against The Pinnacle Ltd & Others in January 2008 afforded protection on three points: • protection of the right of access to the car park entrance from Crosby Square; • protection from water ingress; • protection from vibration by way of set PPV (peak particle velocity) limits at certain times during the working day. The injunction was successfully varied at a hearing in June 2008. An application to vary the terms of the injunction in connection with access was granted and a new Order made by the Technology and Construction Court. Alternative access across the site ensured that access to the car park entrance was maintained whilst demolition above and adjacent to the highway continued. Demolition was completed by June 2008. ==Initial construction==

In late May 2008, a mobile crane and piling rig were on site preparing for construction. It was reported that law firm Davies Arnold Cooper was to take up of office space, and subsequently that the restaurant which was to be at the top of the tower was let. The tower was well under construction, with steel rebar cages already inserted into the ground, which formed part of the piles that would hold the weight of the tower. In November 2008, another piling rig came into use on the site, as well as steel plates for the piles. By March 2009, the longest piles in the UK had been laid. The previous record holder was Moor House with foundations deep. They were sunk below sea level, and below ground level. In Summer 2009, piling had been completed and workers began excavating deep down, ready to begin constructing the basements. The first crane base was put into place in October 2009. In June 2011, Arab Investments announced that they had secured the near £500 million shortfall in the project, meaning that construction work could resume, and by December 2011 the core had reached the sixth floor. A £140 million loan was provided by HSH Nordbank which was subsequently extended three times. In March 2012 the project was halted until at least early 2013, due to problems regarding the pre-let. In December 2012 a settlement offered by Arab Investments to contractors Brookfield Multiplex paved the way for construction to resume "potentially very soon". However, in February 2013 it was reported that the part-built skyscraper could be demolished and rebuilt from scratch based on a less expensive scheme. The following month it was understood that several architects had submitted bids to re-design The Pinnacle, including Ken Shuttleworth, the co-designer of 30 St Mary Axe. In April 2013 it was suggested that The Pinnacle would not restart construction under its original design. However, by December 2013, after an extensive design review, alterations to the interior floor plans were made but the costly exterior was retained with no significant changes. ==Sale and redesign==

In February 2015 the site was acquired by a consortium led by Axa Real Estate in a deal worth £550 million. The building was completely redesigned and a new application for planning permission was submitted in summer 2015 following consultation. That application was approved in November 2015. The concrete central core of the original design was completely removed by December 2015, and construction of the new building commenced in January 2016. The new building, renamed as 22 Bishopsgate, is planned to be tall with 62 storeys. It is estimated the tower will provide approximately of office space and for restaurants, retail outlets and viewing galleries. During the EU Referendum campaign, the developer, Axa, had stated that while they were "committed to the development", they may "revisit the options" if there was a vote to leave the EU. However, despite the leave vote on 23 June, construction continued. In November 2016, a new planning application was submitted which slightly altered the design of the proposed building, as well as reducing its height by 23 metres and to 59 floors to allow for "a cleaner, more elegant resolution to the top of the building in the context of air-traffic control constraints". The application was approved in February 2017. However, these plans were withdrawn, with the developer confirming that the 62-storey, 278 m scheme will be built. During 2017, a suspended girder from the 22 Bishopsgate site struck nearby Leadenhall Tower. Severfield was the steel frame subcontractor to Multiplex's Bishopsgate site. Nobody was hurt. == Initial tenants and facilities ==

22 Bishopsgate is a mixed-use building with 61 levels, the majority of which are office spaces leased to various companies. In addition, the building houses a bike park for over 1,000 bicycles, a food 'marketplace', a public gym (which includes a glass climbing wall overlooking London) and a free public viewing gallery on the 58th floor at 254 metresthe highest viewing gallery in the UK and the highest free viewing gallery in Europe. Tickets are free as a condition of the planning permission for the skyscraper granted by the City of London. ==Gallery==
