Designed by Jekyll's friend and collaborator, Edwin Lutyens and constructed in 1932, it is a Grade II listed structure.

Pevsner describes the whole as "an intricate composition, oddly like Soane translated into the blunt obtuse forms of the 1930s".

[6] The original inscription read 'In remembrance of Herbert and Gertrude Jekyll long time dwellers in their homes in Munstead who passed to their rest in the Autumn of 1932.

This was later updated to include reference to Herbert's widow; 'Also of Agnes Jekyll whose spirit ever dwelt in loving kindness'.

[7] The headboard was also designed by Lutyens and consists of five, pegged, panels, showing the arms of the Royal Flying Corps and carrying details of McLaren's career as a member of parliament and as a second lieutenant in the RFC.
