In 1996 the Secretary of State for Scotland included Prestonfield School as one of Scotland’s Listed Buildings because of its special architectural and historic interest.

There was a spacious area around the school designed for informal play. Mature trees, which predated the building, enhanced this play area and there were extensive lawns and gardens. The external environment has changed radically over the years. The trees were felled, some because of age while others succumbed to Dutch elm disease and the areas of green were gradually erased by tarmacadam.
