Kirk Holdrick, 43, was one of two masked men who smashed their way into the luxury property in February 2023.
Taylor-Joy's rockstar husband, Malcolm McRae, confronted the intruders, then barricaded himself and his wife inside one of the bedrooms.
He was armed only with a lamp as Holdrick and his accomplice attempted to prise open the bedroom door with a crowbar.
But McRae managed to scare off the burglars by shouting, "I have a gun, I have a gun", London's Wood Green Crown Court was told.
Prosecutors submitted that the way the burglars tried to get into the bedroom, rather than simply stealing expensive items, suggested they were intending to target the celebrity occupants personally.
After McRae's gun claim, Holdrick and his partner in crime fled the home empty-handed.
But nine days later, Holdrick struck again, in a second home invasion in which a woman and her daughter were held at gunpoint, tied up, and threatened with violence.
He and accomplice, Ashley Fulton, disguised themselves as police officers for the raid in Dorset, before going on to threaten to burn the daughter with an iron and shoot her dead in front of her mother if she didn't open the family safe.
Holdrick is a career criminal and was jailed for life in 2005 for armed robberies on a security van transporting cash and jewels.
He was recalled to prison to continue serving his life sentence after his latest offences and, in November was jailed for 12 years for the Dorset robbery.
Holdrick has now been handed a further three-year prison sentence for the burglary involving Taylor-Joy and her husband.
The Golden Globe-winning actress, 29, whose work includes The Queen's Gambit, the Dune movies, and Peaky Blinders, appeared on the Baftas red carpet a week after her ordeal.
She was staying at the London property on February 12, 2023 with her husband and his musical partner in the band More, Kane Ritchotte, when the break-in happened, at about 1am.
They heard the glass in a side door of the home being smashed and McRae went to investigate.
When he saw Holdrick and another man - both wearing balaclavas and gloves - forcing their way into the property, the singer and guitarist shouted "hey, stop" before retreating.
He ran back to the bedroom where he and his wife were staying, locked the door and told Taylor-Joy to hide behind the bed.
McRae then armed himself with a lamp as the intruders started to force the bedroom door open with a crowbar.
The rockstar shouted out that he had a gun, prompting them to flee.
When police arrived, Taylor-Joy and McRae were still barricaded inside the bedroom.
The couple told police they had been traumatised by the ordeal and feared being targeted again.
Holdrick pleaded guilty to burglary in December and was sentenced by Judge Barbara Mensah who on Monday ordered him to serve 12 years in prison for that offence, alongside his life sentence, and he was given four extra years on licence if he is set free.
