==Quarrying==
The Hall family had been active in the Croydon area as coal and lime merchants since the 18th. In 1853 they leased an area of land in Coulsdon. In 1864 they closed their quarries at Merstham and increased their quarrying for chalk and flints and use of [[lime kiln]]s in Coulsdon.<ref name="quarry">Surrey Gazette, 19 April 1864</ref><ref>{{cite web|title=Auction, Lot number 15.

This quarry at Coulsdon (Marlpit Lane) was named the 'Stoats Nest Quarry'. The works had its own internal railway system which connected to nearby main lines.

In 1898, the Hall family were refused permission (by their landlord) to build cement works on the Coulsdon site.<ref name="hall3">A century and a Quarter by C G Dobson. Published for private circulation by Hall and Co Ltd. 1951</ref>

The lime principally supplied for waterworks, gas works and tanneries. Demand reduced in 1902 when the Army changed from leather to webbing equipment. And in 1905 there was no longer demand from the gasworks.

Between 1905 and 1910 chalk was supplied for the Halls' cement works at Beddington.<ref>Effects of Mergers By Ruth Cohen, P. Lesley Cook. Page 127.

In 1920, the Hall company purchased 102 acres from their landlord, Byron. This offered their full benefit of the railways and kilns on the land.<ref>The Times (london, England), Thursday, 1 July 1920; pg. 23</ref>

Halls maintained a trading depot in the Marlpit Lane quarry from 1923. It was named the "Ullswater trading estate". The limeworks closed in 1961, and a park now lies in its place.<ref
