The site is a remote island, a strange, still, anomaly of wilderness within highly cultivated agricultural fields. The Flint House and Annex form two stepped, linear monoliths that appear pulled from the landscape as geological extrusions of infinite age, with the rough texture and rawness of their surroundings. The buildings are both viewing platforms and condensing lenses for the surrounding panorama.

The lowest courses of flint are blackest and rough hewn with large gallets in black mortar joints. The walls and terrazzo roofs fade in six coloured strata as the flint progresses up the building, from galleted black through finely knapped grays and finally into courses of long, narrow blocks of white chalk, where the building appears to dissolve into the sky. The watercourse is lined in raw flint nodules, used as it is found in the ground.
