Reading the Layers: Treasurer’s House, York
What a 400-year-old house taught me about reading buildings, honest repair, and why layers matter.
The first thing that struck me about Treasurer’s House was its back wall.
The front, facing a quiet garden beside York Minster, is composed and symmetrical at first glance: a row of curving Dutch gables, tall sash windows, a confident 17th-century face. But walk round the back and the building starts to tell the truth. Gables don’t line up. One lone triangular gable survives where all its neighbours were later swapped for curved ones. Rooflines cut across each other, floor levels step up and down, windows of different centuries sit side by side. You can read rebuilding upon rebuilding, the work of owner after owner, each adjusting what they inherited, a true palimpsest.
I spent a summer volunteering at the house as an architecture student, drawing a new visitor map for the National Trust, and was given access to every room. The deeper I went, the more mysterious it became. Nobody seemed to know for certain when the house was built, or by whom. It became the subject of my undergraduate dissertation, and it has shaped how I look at old buildings ever since.
What was the Treasury?
In medieval York, the running of the Minster was shared between four senior offices: the Dean, the Precentor, the Chancellor and the Treasurer. The Treasurer was responsible for the upkeep of the cathedral building and the safekeeping of its treasures and relics, and for accommodating important visiting churchmen. Funded by estates beyond the city, it became one of the most prized church posts in England.
The Treasurer lived beside the Minster in a house known as “the Treasury.” When the office was abolished at the Reformation and the treasure seized, the house was left to decay. Its name has stuck to the site ever since.
The puzzle
The building’s history had defeated some formidable people. The great architectural historian Sir John Summerson worked on it for the Royal Commission on Historical Monuments in the 1970s, and ended by admitting, in effect, that the problem remained unsolved and it was up to future antiquaries to do better.
The trouble was that the house’s last private owner had deliberately rewritten its story. But by piecing together maps, wills, deeds, earlier histories and the fabric of the building itself, a clearer picture emerges.
An overlooked map. John Speed’s map of York, published in 1610, draws buildings in a kind of axonometric, and shows a house on the site quite unlike today’s: a medieval hall house, with a taller cross-wing at one end and lower service rooms at the other. Earlier investigators had set the map aside as unreliable. Laid over modern aerial photography, its layout is remarkably accurate.
A forgotten dig. In 1989, archaeologists excavating a trench beside the house found a 12th-century wall on a slightly different alignment to the present building. It supports what Speed drew: a medieval hall on the site. Yet it had not been fitted into any of the published histories.
A corrected date. The 18th-century historian Francis Drake recorded that the house had been rebuilt by Robert Squire “about forty years ago,” a claim dismissed because his dates didn’t add up. They do if you count from 1771, the year Drake died, rather than the date his book was later published.
Together, the evidence points to a clear conclusion: the treasurers never lived in the house now called Treasurer’s House. They lived in a medieval building on the same site, which was largely swept away and built over in the early 1600s by Sir George Young, who entertained James I there in 1617. His family extended it into an H-shaped mansion; around 1700 Robert Squire refaced it with Dutch gables and sash windows and split it into two homes. Through the 18th and 19th centuries it was divided, rearranged and extended again, at one point into four separate houses. (One 18th-century tenant, the young astronomer John Goodricke, made discoveries about variable stars here that helped lay the foundations for measuring the universe.)
The house we see is a 17th-century building, reworked many times. The back wall had been telling us so all along.
The fairytale
In 1897 the divided houses were bought by Frank Green, a wealthy Yorkshire industrialist with a passion for antiques. With the architect Temple Moore, he set about “restoring” the house, reuniting it and removing many of the later alterations.
Green believed the house held a continuous history stretching back to the Romans, with each treasurer improving it in turn. So he made it look that way. Floors were taken out to create a double-height “medieval” Great Hall. Each room was dressed in a different historical period as a setting for his furniture collection, a walk-through history of English interiors. Guidebooks written under his influence grew steadily more confident, over the years, that the hall followed the plan of an original medieval one.
One later historian, Rupert Hildyard, called it “an imaginative historical redevelopment masquerading as a thorough, but authentic, restoration.” Green actually demolished more than he repaired. The most impressive rooms in the house are among the most fictitious. In 1930 he gave the house, complete with its collection, to the National Trust.
Historical Plans
Archaeological evidence from each alteration overlaid
It would never be allowed now
Today’s conservation thinking, shaped by the Society for the Protection of Ancient Buildings (SPAB) since William Morris founded it in 1877, is almost exactly the opposite of what Green did. The SPAB-endorsed Old House Handbooksets out its principles plainly: “conserve rather than restore, repair rather than replace.” Retain the patina of age. Make repairs honest, rather than artificially ageing new materials. Respect historic alterations and additions. Avoid trying to put back what has been lost. And embrace good new design.
Green did the reverse on almost every count. He stripped out genuine historic alterations, invented a past the building never had, and disguised new work as old. A scheme like his would never get listed building consent today.
The irony
And yet Treasurer’s House is Grade I listed, the highest protection a building can have.
That isn’t a contradiction. The listing recognises the house as it is: a palimpsest of four centuries, including Green’s own layer. His fairytale is now a century old, and has become part of the building’s story in its own right: a vivid record of how one Edwardian collector imagined the past. The fiction has itself become history.
Which brings me back to the back wall. What makes old buildings so compelling isn’t that they are perfect or pure. It’s that they are layered. As the Old House Handbook puts it, much of their character comes from texture, irregularity and the patina built up over many years. Every honest alteration, even a clumsy one, adds to that story. Erase the layers and you lose the very thing that made the building worth loving.
What it means for your house
Most of us don’t live in Grade I houses beside a cathedral. But the same lessons apply to a Victorian terrace, a flint cottage or a listed coach house.
- Read the building before designing anything. Every house has layers, and the best ideas often come from understanding them. At Well Hill Cottage, reading the house carefully showed that the answer wasn’t an extension but taking away a later addition that wasn’t working.
- Keep what’s genuine. Original fabric, and later alterations with a story to tell, are part of what makes a house special. Repair rather than replace.
- Make new work honest. A new extension, staircase or window should be clearly of its time, crafted with care and respectful of what’s there, rather than a fake copy of the old.
- Think of yourself as a custodian. In William Morris’s words, “we are only trustees for those that come after us.”
That is the approach I bring to every old building I work on. Frank Green wanted his house to look old. I would rather help yours keep being old, and design you add a well-made layer of your own.
