The city's growth is reflected in its growing skyline.^[1] As is the case with many British cities, some of Cardiff's skyline comprises 1960s and 1970s residential and commercial tower blocks. However, current development trends for high-rise buildings include upmarket apartments and office space.

Cardiff is the largest city in Wales and has the most tall buildings in the country.^[2] Designed by Rio Architects,^[3] the tallest building in Cardiff is Bridge Street Exchange at 85 m (279 ft). It replaced Capital Tower in 2018, which, at 80 m (260 ft), which had been the tallest building in Cardiff since 1970.

Cardiff Council considers a tall building within the city centre and Cardiff Bay to be 8 storeys or more or from 25 m (82 ft) in height.^[4] Any proposals to the council for a tall building should "Generally be located within an existing cluster or form part of a proposal to create a new cluster (a cluster can be defined as a group of buildings which form a visual cohesion from more than one viewing point)".^[4]

Notes

1. The Council on Tall Buildings and Urban Habitat estimates that the building is 85 m (279 ft), this is based on a floor count of 25 floors. The estimation has been arrived at by analyzing 8,693 other buildings of the same Residential function on this database that do have confirmed heights. The user should be aware that non-standard features, such as significant spires or raised entrances / podiums, may affect the accuracy of this estimation.^[17]
