Helter Skelter Building London

Progress on the £1 billion skyscraper stopped 14 months ago.

Ken Shuttleworth of make architects told The Guardian the original tower proposal was ‘too complicated to build because each piece of glass is a different size’.

City planning officer Peter Rees said: ‘The Pinnacle, or Helter-Skelter as I prefer to call it, was one of the last of the era of wacky buildings.

A proposal by Lipton Rogers – the new developer launched by Sir Stuart Lipton and former Stanhope director Peter Rogers (brother of architect Richard Rogers) to focus on affordable office developments – is being formulated.

There is an element of posturing here, a chance for architects to showcase their practices, but Arab Investments are most likely to continue with a reduced cost design variation but with the same development team ie contractor Brookfield Multiplex.

BD report today that there is some movement on this major London skyscraper, ie that the architects are loking to reduce costs on The Pinnacle to accelerate progress. We feature some exclusive photos below of the project on site.

Upon completion in 2015 The Pinnacle will be the tallest skyscraper in the City of London, beating both the current tallest – Heron Tower – and the soon-to-be-tallest – The Cheesegrater.

The site for The Pinnacle is in the heart of the City, at 22-38 Bishopsgate, next to Richard Roger’s Leadenhall Building, nicknamed the The Cheesegrater, which is making good progress and is roughly half way up its full height. This cluster of buildings is ‘fighting back’ against Canary Wharf, and winning in both design terms and it terms of building numbers. With the Walkie Talkie Building and 122 Leadenhall Street joining the existing Heron Tower, 30 St Mary Axe, Willis Building, St Helen’s Building, Tower 42 and Lloyds Building (now appearing quite low!) there is a mass of office space to counteract the draw out to the Isle of Dogs, which looked so persuasive at the start of the nineties.

Editor – Adrian Welch.

The stalled construction of The Pinnacle has become the subject of a legal dispute. Brookfield Construction (UK), the contractor, is suing the developers alleging breach of contract and non-payment of fees. Many companies are reluctant to sign pre-let deals that make such speculative schemes viable, hence the funding issues.

Work on The Pinnacle building stopped in Autumn 2011 after the developer struggled to secure the finance to continue the project. It was the second time construction had halted after an earlier delay in 2011. The tower core has been built to just seven storeys and Brookfield has left the site.

The aim is for The Pinnacle to gain an ‘Excellent’ Building Research Establishment Environmental Assessment Method (BREEAM) rating. The Pinnacle incorporates a number of environmental systems including heat recovery, high-efficiency plant, low-energy cooling systems and 1,500sqm of photovoltaic cells incorporated into the unitized cladding panels that wrap around the spiral collar of the tower.

The Pinnacle Construction

Construction work is due to start in the next week on this major London skyscraper designed by KPF.

The 64-storey structure, nicknamed the ‘Helter Skelter‘ has only got up to ground level.

The development is by Arab Investments and is due to complete somewhere between 2012 and 2014.

The Pinnacle – Description

Spiralling 288 meters (941 feet) upward from its base, the Pinnacle tower will form the apex of an emerging cluster of tall buildings in the centre of London’s financial district. Designed to make substantial contribution to the public realm, the project involves reopening a ground-level pedestrian passageway closed to pedestrians by a previous building on the site since the 1980s and linking a number of important public spaces along Bishopsgate and St. Mary Axe.

The Pinnacle interior

The tower’s complex tapered geometry-resolved through advanced computational parametric modeling-comprises inwardly inclined planar surfaces, which are linked by conical surfaces. The design of the entrance canopy at its base responds to the immediate context, creating a zone at the foot of the tower similar in height to nearby buildings. The entrance also signals the historic public right-of-way. The configuration of the entrance evolved during numerous wind-tunnel tests, iterative processes used to find a form that could provide an acceptable pedestrian environment.

Sustainable systems are also integral to the tower’s design. Its aerodynamic shape, for example, improves the performance of the ventilated façade. The façade is made of two layers of clear glass: an inner, sealed (weatherproof and thermally broken) skin and an outer, un-insulated “snakeskin” layer made of repetitively sized, overlapping rectangular glass panels. The gaps between panels allow air to flow into the cavity and permit operable windows ventilate the offices. The outer layer of glass protects against the wind.
