The Estate is the result of nearly 25 years of planning applications and design work and is now available to buy for someone who just happens to have £20 million spare.

The finished product, however, is estimated to be worth five times that much and if a discerning buyer decided to sell it on it could be worth more than £100 million.

Guy Bradshaw, managing director at UK Sotheby’s International Realty said: "This sale provides the opportunity to create a significant and special home that once built, will be one of the UK’s most private and significant homes.

"It has taken over 20 years to secure comprehensive planning approval and we believe it will no longer be possible to build something of this stature in this location. If someone were to spend in the region of £50m on the build, they will have installed every conceivable security feature within the structure and the most spectacular interior finishes.

"This would make it not only the largest new home to be built in the UK for over a hundred years but also the only one built from the ground up.  Designed by one of the most revered architects of our time, offering views that make you feel as though you are living within a Constable painting.

"Once complete, we expect the end value could be in excess of £100m”.
