Portland stone tablets with dedications listing the names of the dead are located in a brick shelter pavilion to the north side of the garden.
Baker had proposed a similar design of memorial cross to the Imperial War Graves Commission (now Commonwealth War Graves Commission), but a different design by Sir Reginald Blomfield was selected instead: the Cross of Sacrifice familiar at many CWGC cemeteries.
The central wheel-headed Latin cross is decorated with roses and lilies representing England and France.
The hipped roof of the pavilion is covered with clay tiles, and the brick floor is laid in a herringbone pattern.
The names of a further 58 men and women were added after the Second World War, along with 34 civilians killed in the 503 bombing raids that affected the area, many targeting the de Havilland aircraft factory nearby .
The memorial was built on land to the east of the Great North Road, near the gates leading to Hatfield House.
