Saturday 5 July marks the 95th anniversary of a landmark moment in British heritage: the donation of Treasurer’s House in York by philanthropist and preservationist Frank Green to the National Trust conservation charity in 1930.

This was no ordinary gift. Treasurer’s House became the first property ever given to the Trust complete with its original contents, setting a national precedent for heritage conservation. Green, a wealthy industrialist from Wakefield, had spent decades restoring the house to reflect his vision of historical elegance – even marking the floor with studs to ensure furniture was never moved.

“If ever you so much as move one chair leg again, I will haunt you till your dying day,” Frank Green, on the meticulous preservation of his home.

But Treasurer’s House was just one part of Green’s legacy. Over the years, he rescued and restored at least eight historic buildings in York, many of which were at risk of decay or demolition. These included a corner plot near Treasurer’s House, now home to the National Trust shop and holiday apartments. Plus, several properties in Minster Yard and surrounding streets, carefully preserved to maintain York’s historic character. Green’s efforts helped to shape the architectural identity of central York, preserving its charm for generations to come.

Step into his world on a “By Appointment” tour at Treasurer’s House, running Saturdays and Monday to Wednesday each week. This hour-long guided experience offers a rare glimpse into Frank Green’s world, his eccentricities, his exacting standards, and the story behind his historic gift.
