Royal Treatment is a side quest in Watch Dogs Legion (WDL) that requires you to locate 3 Abandoned Mansions and photograph them. This walkthrough will guide you to all of the Abandoned Mansion Locations in the Royal Treatment side quest.
Royal Treatment is the 6th side quest of Nowt’s questline. You find Nowt and all her quests in the DedSec Safehouse (Westminster). They become available over the course of the story and can still be done after the story.
Side Quest: Royal Treatment
Starting Location: Starts automatically after completing Nowt’s 5th quest “Nobody Home”.
Quest Giver: Nowt
Requirement: Story Progress & Finish the first 5 side quests from Nowt (The Knowledge > STORMZY Fall on My Enemies > The Walk-In > Human Error > Nobody Home > Royal Treatment)
Rewards: 700 ETO, Mask, Nowt Collectibles (Text Files), A Roof Over Your Head trophy/achievement 
Objectives:
- LOCATE the Abandoned Mansions / ACCESS the ctOS Network / PHOTOGRAPH the Mansions
- INFILTRATE Buckingham Royal Mews / ACCESS the State Room’s Network
- UPLOAD Evidence of Toussaint’s Crimes
- ESCAPE the Area
Starting Location: Royal Treatment
You must finish the first 5 side quests of Nowt. You find her in your DedSec safehouse (in Westminster, marked on the map). If she doesn’t give you any quests you must advance the story further. After doing her 5th side quest “Nobody Home” it will instantly trigger the 6th quest “Royal Treatment”.
LOCATE the Abandoned Mansions / ACCESS the ctOS Network / PHOTOGRAPH the Mansions
What makes this quest special is that it doesn’t give you any waypoints marked on the map. It may seem like it’s bugged, but it’s not. You have to locate the 3 Abandoned Mansions yourself, access a ctOS Panel at each (this gets marked yellow when you are near the Mansion), and then photograph the Mansion (must say “Target in View”). Let’s go through each of the Mansion Locations.
Abandoned Mansion Location #1
The 1st Abandoned Mansion is found in the west of Camden, St. Andrew’s Court.
Abandoned Mansion Location #2
The 2nd Abandoned Mansion is found in the south-west of Westminster, Waxbey house.
Abandoned Mansion Location #3
The 3rd Abandoned Mansion is found in the south-west of Westminster, Strathearn House (very close to the 2nd location).
INFILTRATE Buckingham Royal Mews / ACCESS the State Room’s Network
After you located all 3 mansions, accessed their network and photographed them you receive the objective to access infiltrate the Buckingham Royal Mews. Play as a Construction Worker and use your Cargo drone to fly over the walls. You can select the Cargo Drone from your item wheel, hijack it, climb on it, and fly up.
When you’ve made it past the walls you are told to access the State Room’s Network via the ctOS console in the watch tower. This gives you control of some cameras.
UPLOAD Evidence of Toussaint’s Crimes
Jump between the cameras until you find the Smart Tablet that has the Access Key. It’s in a room where someone is showering, can see it from a long corridor.
After getting the access key, backtrack to the first camera where you spawned. There on the desk you can upload the Evidence.
ESCAPE the Area
Simply escape the hostile area. If you came by Cargo Drone, climb back on and fly away. This finishes the quest.
This finishes Royal Treatment Side Quest in Watch Dogs Legion and unlocks A Roof Over Your Head trophy or achievement.

I was expecting an Edward Kenway reference tbh
Getting the “Target in View” was eluding me from standing photo mode. I switched to my operative with a news drone summon skill and used that. They seem to be preferred in general by the game for photos.
I can’t find either Nowt or Kaitlin in my safehouse after the story is done?
Never mind, fast travelling out and back in worked.
I couldn’t get Target In View to appear whatever angle I tried, then randomly the second objective became available to hack the 3 ctOS hubs, so I did that but then the third and final objective didn’t appear, I still had to photograph the mansions. So I tried again but this time Target In View appeared straight away! Weird. I was then able to complete the mission and get the Trophy.
I didn’t need to do all of the previous missions:
I skipped ‘The Knowledge” and “STORMZY – Fall on My Enemies”
I don’t remember if I did “The Walk-In”? but it’s not on my uncompleted list.
