Some numbers about Madrid (1)

These are some numbers related to the density of the urban core of Madrid, based on gross floor areas as tabulated in the land registry in 2010. The area covered is the scope of the Proyecto Madrid Centro, including 36.833 lots with an agregated area of 33,829 millions sq m and an agregated gross floor area of 101,434 million sq meters; the average floor-area ratio is 2,99.

The first map shows the gross floor area of each lot, in sq m

This map shows the location of the 10 lots with the highest gross floor area; for those knowing Madrid, they are sometimes conventional buildings, but they are located on very large fiscal lots.

The floor-area ratio map shows that the highest ratios are on average on the dense extensions of the 19th and 20th centuries

The ten highest floor-area ratios correspond generally to large department stores or towers

Added gross floor area of  the lots adjoining the Gran Vía, a large avenue (1.300 m long) open through the central core at the begining of the 20th century.

Added gross floor area of  the lots adjoining the Puerta del Sol square (225 m on its long axis), the central point of the urban core.

Added gross floor area of  the lots adjoining the retailing core of Madrid (the commercial streets linking the Puerta del Sol to the Gran Vía), an area with a combined land area of some 150.000 sq m.

Added gross floor area of  the lots included in Azca, the northern business district on the Castellana Avenue (the number is set to grow due to the reconstruction of an arsoned office tower), an area with a combined land area of some 190.000 sq m..

Floor-area ratio in Azca is not substantially higher than in the retailing core of the city, but a different architecture and management scheme has produced a completely different tissue.
