Originally constructed in 1915, Hodge House is a landmark Grade II listed, eight-storey building, situated on St Mary Street in Cardiff’s City Centre. The interior of the building has recently been been renovated into modern, sleek office space.
The filming occurred inside the building and someone inside captured a photo of a logo on the floor familiar to Doctor Who fans.
UNIT, the Unified Intelligence Taskforce, is back after being “put on hold following financial disputes and subsequent funding withdrawal by the UK’s major international partners,” as described in the 2019 Doctor Who New year’s special Resolution.
There are rumours that extras were hired to portray UNIT soldiers in late August when a Doctor Who construction crew was busy building sets inside Hodge House.
What and who were filmed inside Hodge House remains a mystery.
As of 8:00pm on Friday, 17 September, some filming trucks were still present at Hodge House. It is yet unknown how much longer the film crew would remain at the location.
The Doctor Who BBC Centenary special will air in Autumn 2022. It will be the last for Jodie Whittaker’s thirteenth Doctor.
