Discipline of size
At just over 2,000 sq. ft. the main garden is undoubtedly small. There are no hidden corners, or spaces for seasonal borders. We have to be disciplined by the size, as the garden has to work hard - all year round.
As Monty Don asserts "there is no garden however big, however small, however different from your own that you cannot learn from".
Although modest in scale, the garden is nevertheless 50% larger than the average UK domestic garden. Seeing what can be achieved in a garden of this size is probably why so many visitors empathise with it, and find it so inspiring.
