Some tall structures have been proposed that have not yet been built, and may never be. Some structures have been proposed, but construction was never begun, or if begun never completed, and the plans have subsequently been abandoned.

Proposed record breaking structures

  • The Space Elevator is a hypothetical structure that would consist of an approximately long cable connecting a point on or near the equator to an object, possibly a captured asteroid, in geostationary orbit.

  • The Launch loop concept has been proposed for the purposes of orbital launch which would be 80 km high, and would have a cost of around $10 billion.

  • The X-Seed 4000 is the tallest building ever imagined. The X-Seed 4000 "was never meant to be built," says Georges Binder, managing director of Buildings & Data, a firm which compiles data banks on buildings worldwide. "The purpose of the plan was to earn some recognition for the firm, and it worked." Its proposed 4,000 m (13,123 ft) height, 6 km (3.7 mi) wide sea-base, and 800 floor capacity could accommodate five hundred thousand to one million inhabitants.

  • The Shimizu TRY 2004 Mega-City Pyramid is a proposed project for construction of a massive pyramid over Tokyomarker Bay in Japanmarker. The structure would be 12 times higher than the Great Pyramid at Giza, and would house 750,000 people. If built, it will be the largest man-made structure on Earth. The structure would be 2,004 m (6,575 feet) high and would answer Tokyo's increasing lack of space.

  • The Al Jaber Tower in Kuwait City designed by Italian architect Omero Marchetti, part of the planned "ethic city". If built the Al Jaber Tower would reach 1852 m.

  • The Bionic Tower is a proposed vertical city, an extremely large building designed for human habitation, designed by Spanish architects Eloy Celaya, and Mª Rosa Cervera and Javier Gómez Pioz. It would have a main tower 1,228 m (4,029 ft) high, with 300 stories that would house about 100,000 people.

  • Nakheel Tower (previously Al Burj) is a proposed skyscraper, also planned for Dubai, UAE, expected to be approximately tall.

  • The proposed Sky City 1000 is a possible future urban supertall skyscraper project aimed at helping put an end to major congestion and lack of greenspace in the Tokyo, Japan metropolitan area. The plan consists of a building 1,000 m (3,281 ft) tall and 400 m (1,312 ft) wide at the base, and a total floor area of 8 km² (3.1 sq mi).

  • DIB-200 is a possible mixed use supertall skyscraper project proposed by Japanese Kajima Construction, and designed by Sadaaki Masuda and Scott Howe, that if built, would be 800 m (2,625 ft) tall.

  • In USA at several sites, broadcasting towers with heights between 600 and 610 metres are planned according to FCC-database. Some of them will be built close to existing towers of similar height, making them to the tallest tower twins in the world.

Although some refurbishment of the basements started, work was canceled after violent protests by local residents, who feared harmful radiation effects from the high-power transmitter served by the antenna. A new transmission facility with two smaller masts measuring 330 and 289 m was built as a replacement in 1998-99 at Solec Kujawski.

  • Watkin's Towermarker in Wembleymarker, Londonmarker was planned in 1891 to surpass the Eiffel Tower by , but construction stopped before that height was reached due to unstable land. The tower remnants were dismantled in the 1900s, and the site was redeveloped as Wembley Stadiummarker.

  • Construction was cancelled on the Grollo Tower (named after the architect) in Melbourne's developing Dockland precinct in April 2001 after Melbourne's Docklands Authority ruled it out of the tender for development of the Batman Hill's precinct. The area is now occupied by a mixture of smaller commercial and residential buildings. The Grollo Tower would have been the world's tallest building at the time at 560m (1837ft) tall.

The buildings would have been some of the tallest buildings in the world at the time, but were cancelled mainly due to their unnecessary heights which would have dwarfed all surrounding buildings

  • The Ultima Tower is a hypothetical two-mile high skyscraper by architect Eugene Tsui that would be 3,217 m (10,560 ft) tall and comprise 500 stories if built.

  • The Millennium Freedom Tower was a project to be located in Newport, Kentucky, United States was originally proposed in 1998 to be dedicated on Dec 31, 1999.
