The Faraday Building is in the south-west of the City of London. The land was first acquired by the General Post Office in the 1870s, for the Post Office Savings Bank. In 1902 it was converted to a GPO telephone exchange serving sections of London, and underwent several capacity expansions over the next several years. The eastern extension of the building stands on the site of Doctors' Commons whose members had lower-courts say in ecclesiastical (including, during its currency, probate and divorce) and admiralty matters.[1]
In 1933 the original building was rebuilt to house the International Telephone Exchange, more than doubling the size of the building as a whole. The new building included a raised central portion with decorative turrets which was highly controversial at the time as it blocked the view of St. Paul's Cathedral from the River Thames. This led to a new law that restricted the height of new buildings in London to protect the sightlines of the Cathedral.
Although generally five stories high, the central section and rectangular turrets roughly double that and remain a high point in the area in spite of a century of new building in the area. It fronts Queen Victoria Street and backs onto Knightrider Street. The complex is one narrow block west from Peter's Hill which is the northern footpath to/from the Millennium Bridge; the College of Arms stands in the intervening space.
BT Group (which took over the General Post Office's telephone services in the early 1980s) still uses the building, although today it is rented as general offices and retail space.
