His reassuringly expensive £25,000 shed has a wood-burning stove, dimmer switches, sofa bed, sheep’s wool insulation and is painted in muted shades called clunch, mouse’s back and old white.

The exterior is mostly flint; the interior, like that of so many churches in Cambridgeshire, is of "clunch," a hardened form of chalk, well adapted for building, and easily worked for carving.

The oolitic stones are generally so called, although in some countries soft sandstones are used; in some churches an indurated chalk called “clunch” is employed for internal lining and for carving.

Smith adopted for the most part English provincial terms, often of barbarous sound, such as gault, cornbrash, clunch clay; and affixed them to subdivisions of the British series.
