Late in 1916, the Home Postal Depot, Royal Engineers moved to a purpose-built wooden building (200,000 sq ft) on Chester Road, Regent's Park. This new facility contained the depot's administration offices, a large parcel office and a letter office, these last two previously being at the Mount Pleasant Mail Centre. HM King George V and HM Queen Mary visited the depot on 11 December 1916. The depot vacated the premises in early 1920.
