Statement of Special Interest
A-Group with Melsetter House, Chapel, Lodge and Gatepiers, Kitchen and Walled Gardens, Burial Enclosure, Estate Office, Gardener's Cottage, Laundry House and Spinning Cottage. A substantial, largely intact, traditional barn probably of mid 18th century date. Almost the only structure to be left entirely unaltered during the reconstruction of the buildings at Melsetter by W R Lethaby between 1898 and 1900. Presumably this was because Lethaby admired it. Lethaby was a leading exponent and promoter of the Arts and Crafts Movement and widely adopted traditional vernacular features in his buildings. The Melsetter Estate was the home of the Moodie family from the later 16th century until the earlier 19th century. It is likely that the barn might date from the ownership of Benjamin Moodie, who was the laird in the mid 18th century. When the estate was bought (and the buildings at Melsetter redeveloped) by Thomas Middlemore, a Birmingham industrialist, in 1898, it comprised the entire island of Hoy as well as the adjacent smaller islands of South Walls, Fara and Rysa. It was called 'The Hall' because functions were held here (information from Elsie Seater of Melsetter House).
