The garden was designed by T H Mawson for Lord Leverhulme. Then known as Roynton Cottage, it was sited on a hill with fine views. The garden was once a fine example of the Arts and Crafts style. It fell into extreme decay and was partially rescued by volunteers. The 'Cottage' has gone completely but one can admire the stonework of the Seven Arched Bridge and the Pigeon Tower, which survive. The Pigeon Tower has 3 storeys and was used as lookout, with Lady Lever's a sewing room on the top floor. The Japanese Garden was inspired by Lord and Lady Lever's trip to Japan and was designed by by Thomas Mawson in 1922. It has a lake, two waterfalls, lanterns and a tea houses.
The design approach explained in the below video is commendable.
