An octagonal house built in the 1790s for 2 cousins, Jayne and Mary Parminter who filled it with collections of curios. The Shell Gallery was influenced by the Grotto Rooms of Isola Bella on Lake Maggiore.
Endsleigh House (1814) is the last Repton landscaped garden and sits north of Tavistock overlooking the Tamar. It features a Grade 1 listed, hexagonal shell house in a ravine landscape.
Since 1976 Dr John Marshton has landscaped a picturesque garden that includes a Temple to Pan, Turkish Tent and Shell House. He designed the Italianate structure and shell patterns using many local types from Croyde.
The Shell House seems to date from c1817. The unusual monopitch structure is still intact but the interior stalactites are in a ruinous condition.
