[4] Swan Lane Mills are typical of the final phase of cotton mill construction in Lancashire, of vast size and decorated with flamboyant terracotta embellishments reflecting the industry's prominence and prosperity.
[10] Both mills are of five storeys over a basement and were built in the same style with wide segmentally arched windows and flat concrete roofs.
The mill chimney has been reduced in height but retains an emblem of a swan in white lettering.
[3] No.1 Mill is 25 bays wide and five deep with a single storey and basement extension to its north side, possibly a card room, but now used as a warehouse.
3 Mill of 1915 is brick built with stone dressings, rounded corners and a ridged slate roof.
It is 23 bays long, 14 wide with segmentally headed windows and eight storeys high (six plus a double attic).
The south-west corner entrance has a panel with a carved swan above the doorway and accesses a staircase.
3 Mill was powered by a 2000 hp vertical triple expansion engine also supplied by Saxons.
[11] In 1983, Swan Lane Mills was featured in an episode of the documentary Fred, in which Fred Dibnah is hired to remove the decorative ornamental on top of the chimney[12] by then the last decorative topped chimney in Bolton.
