Limited accommodation resulted in the acquisition of further land in South Woodford (now directly connected to Mile End tube station by means of the Central line's eastward extension), upon which tower blocks were established. The College also obtained the Co-operative Wholesale Society's clothing factory on the Mile End Road which was converted into a building for the Faculty of Laws (and some other teaching), as well as the former headquarters of Spratt's Patent Ltd (operators of the "largest dog biscuit factory in the world" – see Spratt's Complex) at 41–47 Bow Road, which was converted into a building for the Faculty of Economics founded by Maurice Peston, Baron Peston. Both faculties were physically separated from what was now a campus to the west.
