Strangers - John Simm (2018) - FEHD Quarters, Sai Yee Street

David and Lau Chen's flat makes another appearance in Episode 2, however, I recently went for a wander in the area and took a quick photo of the section that was used in the filming and I can confirm that only the exterior was used. The reason is because it appears (from my photo) that the end doorway used for the flat is in fact the entrance to the building's stairwell! You can see the Exit sign above the lintel in my photo (see last image).

The first image shows Jonah (John Simm) getting out of a cab on Sai Yee Street with the FEHD building behind him. On the left is where the Mongkok Road pedestrian bridge where it turns left to continue on towards Mongkok East station and the (now named) Moko mall. It looks like sometime in the past the bridge either connected to or was intended to connect to the FEHD building. It's been blocked off for as long as I can remember.

Strangers - John Simm (2018) - FEHD Quarters, Sai Yee Street

David Chen lives with his daughter, Lau, in a rather spacious apartment by HK standards. I've since read that pretty much all of the interiors were filmed back in the UK at the beginning of 2018, however, I should say that the building used in the show is an old Colonial Govt quarters, so the size of the studio set might actually be fairly close to reality given the generous size of Govt accommodation of old.

Anyway, this is the old accommodation block for the Food and Environmental Hygiene Department. The FEHD came into being after the abolition of the (democratically elected) Urban Council, but I suspect the building has been around a bit longer than that given its architecture.

We get quite a few nice views up Sai Yee Street and also along Mongkok Road - you can see the roof of the walkway from the East Rail station as it turns a 90 degree angle just outside the apartment building.
