1. Manchester Civil Justice Centre. Manchester UK
It comprises of 47 court rooms, tribunal and hearing rooms plus offices and facilities for judges.
In addition to being a courthouse it is also the new north-west England headquarters for the Department of Constitutional Affairs.
On completion in 2007 it had the largest glass wall in Europe: a 63m by 60m cavity glass wall as a façade along its western edge supported by sixty metre high triangular atrium columns all suspended from the 11-storey atrium roof.
2. Gherkin Building; London UK
The Gherkin is London’s most instantly recognisable tower. Totalling 500,000 sq ft, The Gherkin is an iconic structure housing a flourishing community. The Gherkin deserves its reputation for being ‘the most civilised skyscraper in the world’.
3. Lloyd’s Building; London UK
The Lloyd's building (sometimes known as the Inside-Out Building) is the home of the insurance institution Lloyd's of London. It is located on the former site of East India House in Lime Street, in London's main financial district, the City of London. The building is a leading example of radical Bowellism architecture in which the services for the building, such as ducts and lifts, are located on the exterior to maximise space in the interior.
Twenty-five years after completion in 1986, the building received Grade I listing in 2011; it was the youngest structure ever to obtain this status. It is said by Historic England to be "universally recognised as one of the key buildings of the modern epoch"
4. London City Hall; London, UK
City Hall is part of the More London development located between London Bridge and Tower Bridge, on the south bank of the Thames. It was designed by Foster + Partners, one of Britain's leading architects. Every element of our building is designed to work alongside every other element, to keep the building cool or warm in an environmentally friendly way.
In 2014 / 2015 City Hall emitted 1,985 tonnes of carbon dioxide. This is better than the average amount for similar buildings.
5. Millennium Dome, London, UK
The structure solved with great elegance the problem of how to enclose and protect the separate exhibition ‘zones’ from the vagaries of the British climate. Providing 100,000 square metres (1.08 million square feet) of enclosed space within a 2.2 million-cubic-metre (77.7 million-cubic-foot) volume, the structure is 365 metres (1,200 feet) in diameter, with a circumference of 1,000 metres (3,280 feet). The Dome, with a maximum height of 50 metres (164 feet), is suspended from a series of twelve 100-metre (328-foot) steel masts, held in place by more than 70 kilometres (43.5 miles) of high-strength steel cable that, in turn, support the Teflon-coated glass-fibre roof.
More than 6 million people visited the attraction during 2000. The inherent flexibility of the structure is such that it has since been used as a sporting venue for the London 2012 Olympic Games. Currently the Dome is an entertainment hub known as The O2 and features the 20,000 capacity O2 Arena – one of the world's most successful music venues – at its heart.
