MacIntyre took over Mount Tabor House, Wingrave. It had been run by catholic nuns of the Order of St Mary of the Cross for young women with learning disabilities since the WWII, and was closing down as the Order had become depleted and the nuns could not carry on their work. MacIntyre was asked to take it over. MacIntyre raised funds to renovate the building, a nineteenth century manor house originally built by the Rothschild family. This was a significant turning point for MacIntyre, as the property was a gift, making the project financially viable. The school developed into the base where younger children were educated, until they reached about the age of sixteen and were transferred to Westoning for a more adult life.
