After serving as a private house it became a school and most recently (2015) has passed into the ownership of the Beith Development Community Trust.
Thomas, John and Timothy Warren inherited in turn before an insurance manager, Robert James Cecil Govan and his wife Jean Kinniburgh Templeton purchased the property in around 1923.
[2] In 1942 a builder, Charles Scott Gray purchased Geilsland for £1750,[2] followed by Norman Dunlop McCombe family who were involved in the fruit trade.
The Church of Scotland then obtained and used the house, chapel, gymnasium and dormitory blocks from 1963[3] as a special school until closure of the facility in 2015 and its sale to the Beith Development Community Trust Ltd. later that year.
A pair of late 19th-century Gothic semi-villas at 28 and 30 Portland Road, Kilmarnock are believed to be by Ingram and clearly possess architectural details comparable with Geilsland, in particular the entrance porch with its columned supports.
[12] In late 2015 Geilsland House and associated buildings were sold to the Beith Development Community Trust with financial assistance from the Scottish Land Fund.
It was built by the head teacher of wood craft and joiner William Jenkins with help from staff and pupils as a conversion of a stable and barn, with pews and pulpit coming from the East Church in Millport, Isle of Cumbrae.
This was a written contract between them, setting out the terms of possession of assets, control her late father's property and potential details of who would inherit after her death.
