Task: Question Answering
Input (English): Passage: The Artizans, Labourers & General Dwellings Company (Artizans Company) was established in 1867 by William Austin. Austin was an illiterate who had begun his working life on a farm as a scarecrow paid 1 penny per day, and had worked his way up to become a drainage contractor. The company was established as a for-profit joint stock company, with the objective of building new houses for the working classes "in consequence of the destruction of houses by railroads and other improvements". The company aimed to fuse the designs of rural planned suburbs such as Bedford Park with the ethos of high-quality homes for the lower classes pioneered at Saltaire. Whilst earlier philanthropic housing companies such as the Peabody Trust and the Improved Industrial Dwellings Company focused on multi-storey blocks of flats in the inner cities, the Artizans Company aimed to build low-rise housing in open countryside alongside existing railway lines to allow workers to live in the countryside and commute into the city. The company attracted the attention of Lord Shaftesbury, who served as president until 1875.
The company built and immediately sold a group of houses in Battersea, then still a rural village. The proceeds of the sale were used to purchase a plot of land in Salford for development, and by 1874 the company had developments in Liverpool, Birmingham, Gosport and Leeds.The first of the four large-scale estates built by the Artizans Company was Shaftesbury Park, a development of 1,200 two-storey houses covering 42.5 acres (0.17 km2; 0.07 sq mi) built in 1872 on the site of a former pig farm in Battersea. The success of Shaftesbury Park led to the construction of Queen's Park, built in 1874 on a far more ambitious scale on 76 acres (0.31 km2; 0.12 sq mi) of land to the west of London, adjacent to the newly opened Westbourne Park station, purchased from All Souls College, Oxford. A third London estate was planned at Cann Hall, and a site of 61 acres (0.25 km2; 0.10 sq mi) was purchased.However, the Queen's Park project suffered serious mismanagement and fraud; the company secretary William Swindlehurst and two others were found guilty in 1877 of defrauding £9,312 (approximately £861 thousand today) from the project. The company was forced to raise rents, and tenants were no longer permitted to buy their houses; by 1880 the company's finances had recovered sufficiently to allow further expansion.
