Buildings that were never realised
 The Volkshalle, Germany
The Volkshalle (‘Hall of the People’) was a monumental design that was to have served as the architectural centrepiece for Adolf Hitler’s capital of Germania. Designed by the architect Albert Speer, it would have comprised an enormous dome inspired by Rome’s Pantheon.
The projected measurements of the Volkshalle demonstrate the scale of the ambition. A massive stone podium 315 x 315 m (1,033 x 1,033 ft) and 75 m (250 ft) high would have served as the base on which the dome sat. The granite dome was to measure 290 m (950 ft) high, with a diameter of more than 250 m (820 ft), and an oculus at the top measuring 46 m (150 ft) in diameter.
Inside, the structure would have contained a massive apse, beneath which Hitler could have addressed more than 180,000 people sat in three tiers of seats around a giant circular arena.
Not only would the structure have dominated the skyline of Berlin, it would have far surpassed the likes of St. Peter’s Basilica or St. Paul’s Cathedral. Indeed, many structural experts have claimed that such a large dome would have been impossible to construct.
Experts have also speculated that the size of the dome would have made acoustics very difficult to control, while Speer himself believed that in cold weather the hall could actually experience indoor rain as a result of the breathing and perspiration of so many people.
 Palace of the Soviets, USSR
The Palace of the Soviets was to have been a gigantic congress hall and administrative centre near the Kremlin in Moscow.
The palace was to have been 415 m (1,362 ft) tall, crowned by a huge bronze statue of Vladimir Lenin which, by itself, would have measured 80 m (260 ft) and weighed more than 6,000 tons. There are even reports that the inside of the statue’s head would have been accessible as a library.
In 1931, the Cathedral of Christ the Savior, a potent symbol of ‘old Russia’, was demolished with the intention of building the Palace in its place. In 1937, construction began with the laying of the foundations and the beginning of the steel frame. However, this was as far as work progressed, as a lack of materials and manpower caused delays, with the steel frame gradually disassembled for use in fortifications and bridges.
The project was abandoned after the Second World War, with the foundations converted into the Moskva Pool, which was the largest open-air swimming pool in the world. In 1995, shortly after the fall of the Soviet Union, the pool was demolished and a full-scale replica of the Cathedral of Christ the Savior restored instead.
 Phare du Monde, France
Phare du Monde was an observation tower to be built on the outskirts of Paris, originally intended for the 1937 World’s Fair. Designed by the engineer Eugene Freyssinet, the concept was promoted as a ‘Pleasure Tower Half Mile High’, as it would have measured 701 m (2,300 ft) tall.
As a powerful symbol of constructivism and modernity, the tower would have been built using iron, glass and steel, and take the form of a double helix. It would have spiralled up to a height of 400 m (1,300 ft), far surpassing the Eiffel Tower.
Four major geometric structures were to be contained in the tower’s main framework, each of which would rotate at different speeds. The first, a cube, would have been located at the base and used as a conference and meeting venue, completely rotating over the course of a full year. A small pyramid would have been above the cube, completing one full turn every month. A cylinder above that would have rotated once every day. The tower in its entirety would have fully rotated every year.
 The Illinois, Chicago
Despite being more than four times taller than any structure built at the time, Wright believed that his design was technically feasible. To counteract the discomforting sensation of the tower swaying in the wind, Wright proposed a tripod design combined with the tensioned steel frame.
 Buckminster Fuller’s New York dome
But Fuller took his dome plans to another level when, in 1960, he proposed a 3 km-wide, 1.6 km-high geodesic dome that would span Midtown Manhattan. He intended for it to cover the island from the East River to the Hudson RIver, from 21st Street to 64th Street.
The dome was intended to regulate weather and reduce air pollution. It would be maintained at a moderate temperature, meaning that buildings would not be individually heated and cooled, allowing costs to be reduced. He claimed that the dome would prevent snow and rainfall, and control the effects of sunlight. The cost of snow removal in New York City, Fuller said, would pay for the dome in just a decade.
 Cénotaphe à Newton
Étienne-Louis Boullée (1728-1799) was a French neoclassical architect whose unique style was exemplified in his outlandish proposal in 1784 for a cenotaph for Isaac Newton, who was revered during the Enlightenment period.
The cenotaph was to have been a 150 m (500 ft) diameter sphere embedded within a three-tiered cylindrical base, giving the impression that it was buried. The figure of the sphere was completed with a flanking pair of curved ramps, while closely-spaced cypress trees were to circumscribe each level.
Rising as it reaches the centre, a final flight of stairs would bring visitors into a cavernous void – the ‘centre of gravity’ – containing Newton’s sarcophagus.
Boullée’s use of light in the building’s design was intended to change the appearance of the interior. At night, an oversized luminaire suspended at the sphere’s centre would radiate light through the long entry tunnels, whilst during the day, a black starlit night would blanket the interior.
Gaudi's designs do not look too dissimilar to his master-project, the Sagrada Familia, not least because of the grand scale and the arrangement of a large, central parabolic tower that would be taller than the domed towers adjoined to it. He planned a 'Homage to America' room which would measure 125 m in height and contain a 10 m-high replica of the Statue of Liberty.
 Ville Contemporaine
Ville Contemporaine was a mass housing project planned by the architect Le Corbusier. He believed that his design was an efficient solution to the unsuccessful attempts by French officials to deal with the urban housing crisis. His project was intended to house 3 million people in an entirely new city.
At the centre of his plan was a group of 60-storey cruciform skyscrapers built on steel frames and wrapped in glazed curtain walls. These were set within large, rectangular green spaces and would contain offices and apartments for the most wealthy inhabitants. Moving out from the skyscrapers, smaller multi-storey zig-zag blocks were to be set in green spaces to house the 'proletarian' workers.
