Inclined building

An inclined building is a building that was intentionally built at an incline. Buildings are built with an incline primarily for aesthetics, offering a unique feature to a city's skyline, as well as framing other buildings and structures between them when built in pairs.

Puerta de Europa, the first inclined skyscrapers ever built.^{[citation needed]}

Design

Despite the outward appearance of an inclined building as "leaning-over", they are as structurally sound as any non-inclined building. The mass of the building's upper floors is always equal or less than the mass of the building's lower floors, ensuring the building remains balanced around its centre of mass.

The upward slope of an inclined building is not to be confused with the upward slope of an otherwise non-inclined building, such as 122 Leadenhall Street in London. It should also not be confused with the top-heavy design of an otherwise non-inclined building, such as Vancouver House in Vancouver.

Tallest inclined buildings

As of October 2019, this list includes all intentionally inclined buildings (completed and architecturally topped out) which reach a height of 30 metres (98 ft) or more, as assessed by their highest architectural feature. This includes spires and architectural details but does not include antenna masts.

Rank	Name	Image	Location	Country	Height m (ft)	Floors	Inclination	Completed	Notes	Ref
1	Altair - East Tower		Colombo	Sri Lanka	209.1 m (686 ft)	68	13.8°	2019	Completed 2021. Tallest inclined building in the world since 2019, as well as the tallest building in Sri Lanka. Its inclusion on the list is arguable as it is not entirely self supported, there is a structural connection to the project's West Tower on the leaning side.	[1]
2	Capital Gate		Abu Dhabi	United Arab Emirates	164.7 m (540 ft)	36	18°	2011	Tallest inclined building in the world from 2011 to 2019.	[2]
