I found this pillbox by chance while on a hike along the coast a few years ago. On first inspection, it appears to be a standard Type 24 constructed with concrete block, similar to breeze blocks. Upon closer inspection, the blocks appear to be have been precast, including what must be bespoke corner blocks angled specifically for this design of pillbox. The aggregate in the concrete appears to be beach gravel which may have been collected locally from the nearby beach.
A lime mortar has been used to bond the block together which has eroded out of the top few courses of brick, and the calcium can be seen staining the outside of the pillbox.
If these blocks are indeed precast it has a lot of similarities to the Christchurch Block Sangar developed in the mid-1980s.

Arguably the only real precast concrete pillbox of the war; the Norcon provided light protection from small arms to the occupants. Supplementary protection would have been provided from sandbags or earth banks against the sides.
It is not to be confused with the 1980 Yarnold Sangar which can still be seen around the perimeter of many Cold War airforce sites.

Laying the wooden formwork for the back hatchway concrete repair. Note that I covered the wood with paper for easier separation once the concrete was dry. Early October 2011.
