Part III. of the Act embodied the idea, originally started by Lord Shaftesbury in 1851, as to the erection of labouring classes’ lodging-houses by the local authorities, and grafted several amendments thereon.
Power was given for the acquisition by the Council of land for the purpose of erecting lodging-houses thereon. Such land, however, was to be within the Council’s jurisdiction. Under this part of the Act the Council erected a common lodging-house in Parker Street for the accommodation of over 300 persons. It also acquired several sites, including the Millbank estate, upon which it proceeded to build houses; and one of 38 acres at Lower Tooting for the erection of cottages thereon.
Altogether the work performed under the Act was considerable, and the housing for the accommodation of the working classes made sensible progress, the sites sold by the Metropolitan Board of Works to trusts, and public companies, and private persons, having been built upon and covered with artizans’ dwellings.
Private building was proceeding at considerable pace, and in many parts of London the ground was becoming more overcrowded than ever with houses.
The older parts of London were being rapidly re-built, and open spaces at the rear of buildings were being gradually covered by buildings.
Of St. Pancras the Medical Officer of Health wrote (1896):—
“… There is a prospect that in course of time the whole of the open space about buildings may disappear…. Old houses possessing yards, areas, open spaces, in some form at the front or back or both, are being re-built in such a manner as to entirely cover the whole ground area two or three storeys up—leaving not a particle of open space.”
The restrictions imposed by the Building Acts were of the most illusory character, and as the Acts were mostly future in their operation, and not retrospective, their effect was also limited. Any “owner” was entitled to re-build on “old foundations,” no matter how crowded the houses were on the spot, so new buildings were usually only a resurrection in huger and more perpetual and objectionable form of the evils which ought, as far as possible, to have been eradicated.
During the year 1894 the London Building Law was consolidated and amended. The Act recognised, for the first time in London, the principle that, in addition to the height of the building being proportionate to the width of the street on which it abuts, the amount of open space about the rear of a building should also be proportionate to its height, and hence the future crowding of buildings on area was put under limitation.
