Twenty-Six Buildings That Changed the English Landscape

Why the Fortunate Few Must Continue to Build What Cannot Be Justified

The garden folly has always been difficult to defend on rational grounds. It serves no practical function. It cannot be assessed by the normal metrics of programme, efficiency, or return. It exists, in the most fundamental sense, because someone with the means and the imagination decided that it should — and because they understood, perhaps instinctively, that a landscape without a deliberate architectural act at its centre is a landscape that has not yet been completed.

That understanding is not widely shared. It belongs, in each generation, to a relatively small number of clients who combine the resources to commission work of genuine permanence with the cultural formation to understand what permanence in architecture actually demands. In the Georgian and Regency periods, those clients were the great landowners — the Hoare family at Stourhead, the Temple family at Stowe, the Coventry earls at Croome and Broadway — who built not for themselves alone, but for a landscape that would outlast them by centuries.

The argument for continuing this tradition in 2026 is not nostalgic. It is not about recreating the Georgian landscape garden or commissioning pastiche temples for contemporary estates. It is about understanding what the folly tradition actually represents: the belief that the designed landscape is a serious cultural endeavour, that architecture in a garden context demands the same rigour as architecture anywhere else, and that the buildings placed in a landscape have the capacity to shape how that landscape is experienced and understood by everyone who encounters it — not just the patron who commissioned them.

Stourhead receives over 400,000 visitors a year. Rousham, privately owned and unchanged since William Kent left it, receives far fewer — but those who make the journey to Oxfordshire to walk the circuit of the walled garden, to see the Praeneste and the Temple of the Mill and the Eyecatcher at the garden's boundary, understand something about the relationship between architecture and landscape that no amount of reading can fully convey. These buildings are working. They are doing precisely what they were designed to do — giving a landscape a reason, a narrative, a structure — nearly three hundred years after the last craftsman left the site.

The clients in each generation who commission work of this quality are, without exception, those who accept that the brief cannot be fully justified on rational grounds. A prospect tower on a Cotswold hill cannot be justified. A classical pavilion on a Belgravia garden cannot be justified. A secure garden studio within the curtilage of a listed country house cannot be justified — not in the language of return on investment or programme efficiency. It can only be understood in the language of what it gives to the landscape, and what the landscape gives to everyone who experiences it.

That language has been spoken continuously in England since the early eighteenth century. The buildings that embody it — from Vanbrugh's rotunda at Stowe to Beckford's tower above Bath — are among the most visited, most studied, and most loved structures in the country. They were built by the fortunate few. They belong, in every meaningful sense, to everyone.

The commission that begins this week, in the conversations that Chelsea always starts, will not be justified by any rational argument. It will be justified by the building itself — by its presence in a landscape that needed it, by the quality of the thinking that produced it, and by the simple, irreducible fact that it will still be standing, still doing its work, long after every other decision made in May 2026 has been forgotten.

That is reason enough. It always has been.
