(previously 3582sq.m.) and 1483sq.m. of external plant - total area for both Type 'A' is 11972sq.m. (previously 11094sq.m.); Two Type 'B' buildings each with 1872sq.m. of data halls, 419sq.m. (previously 67sq.m.) of offices/reception; 1879sq.m. support space/staff facilities/internal plant giving a total internal floor area of 4170sq.m. (previously 3005sq.m.) and 1483sq.m. of external plant - total area for both Type 'B' structures is 11306sq.m. (previously 9996sq.m.) The Data Centre part of the building is single storey reaching a maximum of 8.6m in height; the plant area is to a maximum of 10.7m high (increase from 9m) and the tallest building is Type 'A' office building is 12.5m in height (increase from 10m). 4 substations accessed from the estate road to facilitate the development are now proposed; each has an area of 49sq.m. and will be 3.75 metres in height. The development will be constructed in 5 phases initially with the enabling site works and 2 substations; the subsequent phases will contain a single warehouse building starting with the northern-most building. A total of 84 car parking spaces will be provided together with recycling storage and all ancillary services and landscaping.
