He had previously drawn up plans to rebuild the cattle market at Smithfield, before the Corporation decided to remove the trade in live animals to a site outside the City itself.
[1] The market originally covered 30 acres (0.12 km2) of the site and grounds of Copenhagen House, so named as the location of the Ambassador of Denmark's residence in the 17th century.
Livestock could be conveniently transported to the depots before being driven the short distance up York Way to the market or walked down from Holloway cattle dock and Junction Road railway station.
The central market area was arranged in a rectangle with stalls and pens for cattle, sheep and pigs and a 46 metres (151 ft) tall central clock tower, today the Caledonian Park Clock Tower as the major remaining element of the market area, otherwise having been turned into the Caledonian Park.
A fifth pub, The Butchers Arms, built to a similar design, was located at the south-west corner of the market site at the junction of York Way and Brewery Road.
At the break-up of the GLC, Market Estate was transferred to the control of the local authority, London Borough of Islington.
