Latchmere House

Tucked away in the leafy London suburbs of Ham and Kingston upon Thames sits an elegant Victorian mansion with a surprisingly notorious past. Latchmere House has undergone a dramatic transformation from luxurious family home to top secret WWII interrogation center and prison before being reborn in recent years as stylish modern apartments.

This handsome building has played a little-known but important role in British 20th century history. Join us as we uncover the strange and colorful story behind this unassuming architectural gem.

History of Latchmere House

Latchmere House was originally constructed in the mid-19th century as a grand rural estate for the wealthy Victorian engineer Joshua Field. With its striking Gothic-inspired design, the lavish country house was a peaceful sanctuary for Field and his family.

But world events would soon intervene to radically alter Latchmere House’s destiny. With the onset of World War I, the British War Office took over the building and converted it into a hospital for treating officers suffering from shellshock.

Wartime Detention Center and Infamous Interrogations

The mansion’s next incarnation was even more dramatic. During World War II, Latchmere House operated as a top secret detention and interrogation center run by MI5. Codenamed Camp 020, it held captured German spies and British Fascist sympathizers without trial.

Notorious for its solitary confinement cells and experimental interrogation techniques, Camp 020 tried to extract vital information from prisoners of war and fascist detainees. Mock executions, food deprivation and psychological torture were all common.

Controversial Imprisonment of British Fascists

Many high-profile members of the British Union of Fascists (BUF) like leader Oswald Mosley were also imprisoned here. After being subjected to the grueling interrogation methods, Mosley launched legal proceedings and the fascists were eventually released.

Transformation into HMP Latchmere House

In 1948, the government transferred Latchmere House to the Prison Service. It initially served as a youth detention facility before becoming an adult prison.

Young Offenders Institute and Remand Center

The first prisoners held here in the 1950s were young delinquents like the notorious Ian Brady, later known for his Moors Murders. It then transitioned into a remand center temporarily housing inmates before trial.

Category D Resettlement Prison

But by 1992, Latchmere House underwent a dramatic change of role. It now operated as an open Category D prison preparing inmates for release back into society.

Prisoners lived in relaxed, unlocked conditions and could take up employment outside. A 2003 inspection praised the resettlement programs helping prisoners transition successfully. Inmates typically engaged in 57 hours of purposeful activity per week, making it one of Britain’s most active prisons.

Closure Under Budget Cuts

Despite this progressive model, HMP Latchmere House fell victim to budget cuts and closed permanently in 2011. The Victorian mansion was sold off for redevelopment.

Berkeley Homes Redevelopment

The historic estate was purchased in 2013 by the Berkeley Homes developer. Though English Heritage denied listed status for Latchmere House, its architecture was still protected.

Berkeley Homes sympathetically converted the main house into luxury apartments. But the prison buildings were demolished to make way for a new residential community. With planning approval, the developers built 73 modern homes on the grounds.

The original Victorian character of Latchmere House has now been restored. But echoes of its turbulent past remain in local memory.

Location and Geography

Geographically, Latchmere House straddles the border between the London boroughs of Ham and Kingston Upon Thames.

The mansion is situated adjacent to the green open space of Ham Common, benefiting from a leafy semi-rural environment despite being in Greater London.

The nearby Thames River connects Latchmere House to central London only 9 miles away. Fast transport links provided easy access for the government officials and prisoners that once frequented this out-of-the-way mansion.

Current Status

Today, Latchmere House has come full circle returning to use as a residential community. The main Victorian building now contains 7 upscale apartments.

And the new homes constructed on the grounds blend modern open-plan living with the site’s heritage architecture. Only the high brick perimeter walls remain as a reminder of its prison past.

The unique history of Latchmere House is encoded into its red brick and Portland stone walls. This elegantly understated building has borne witness to war, detention, interrogation, and imprisonment before its tranquil rebirth for the 21st century.


Through times of war and peace, Latchmere House has shown a remarkable resilience.

Built for a privileged family, requisitioned for secret government operations, then re-purposed as prison and infamously feared interrogation center before becoming a reformed model for inmate rehabilitation.
