It may not be 221B Baker Street, but 46 Hornsey Lane Gardens would be provide a temporary home for Sherlock to stay safe and hidden while still being able to access all the places important to him.
Sherlock needs to stay hidden within London. He has gained fame and a reputation through the tabloids from his high-profile cases, so he is recognizable to much of the public. He needs to avoid where many people might spot him. Sherlock wants to keep tabs on his close family and colleagues—John Watson, DI Lestrade, Mrs. Hudson, Molly Hooper, and Mycroft Holmes—and have access to them (without them knowing). To remain anonymous and continue the mirage of his death, Sherlock must pick a very particular place to hide out. We are here to find him a new flat in London.
Sherlock Holmes is arguably the world’s most famous fictional detective. His job solving crimes in London is often dangerous. In “The Reichenbach Fall,” BBC’s modern adaptation, Sherlock publicly commits suicide to end his battle with his nemesis, Moriarty, and save those he cares about. However, his death is actually faked, and he spends several years afterwards in hiding.
Through careful research (i.e. watching the episodes), we determined Sherlock’s preferences for locating a new apartment and analyzed them with the method below
By collecting our data and creating constraint and opportunity buffers to assign weights to, we created this suitability map showing the best general areas that Sherlock should live in, highlighted in green. These results show that the most suitable areas are generally in the outer parts of Greater London.
In our network analysis, we plotted Sherlock’s seven desired locations and discovered that, contrary to the suitability results, the specific facilities that Sherlock wants to easily access (red) were mainly in central London.
Constraints Weight Opportunities Weight
Police stations to avoid the police, whom he doesn’t trust
1200 m buffer; weight = -2
Low population density < 95 indiv.per sq. km.; weight = 1
Tourist locations so he doesn’t get recognized
800 m buffer; weight = -1
Metro stations to easily get around London
700 m buffer; weight = 2
Hospitals to continue his research privately
1000 m buffer; weight = 2

We had to figure out how to consolidate the two contrasting results. Ultimately, we located apartments in the five suitable areas closest to central London. In doing this, we searched London real estate listings and selected an apartment from each. We plotted these five apartments as facilities and ran a Minimize Impedance problem under location-allocation to find the location most accessible to the seven demand points.
In suitable areas, select five 1-
bedroom flats no higher than the third
floor available for rent.
Solve location-allocation problem to find the flat (facilities) most accessible to all 7
addresses (demand points)
