Taylor Swift reportedly has plans to make her boundary walls 12-14-feet high after another security breach at her Beverly Hills home.

The international pop star, 28, built 7ft walls last November but an intruder was arrested in April for scaling the wall and refusing to leave.

According to TMZ, Taylor has been granted permission to double the height 'to improve security and privacy.'

Protection: Taylor Swift has reportedly been granted permission to double the height of her boundary walls at the LA home she's owned since 2015

Despite Taylor's efforts to keep intruders at bay, new documentation claims there have been 'multiple attempts by people to enter the property over the existing, lower perimeter wall.'

The cinder-block wall will reportedly be covered with box ivy and bushes for maximum privacy, but also to improve the aesthetic.

Two months ago, 23-year-old Justin Christoph Lilly was arrested for trying to scale a wall at her Beverly Hills mansion

According to PageSix, Lilly was 'charged with trespassing and refusing to leave private property.'

Private: The permits originally included permission to build a 7ft high retaining wall by her tennis court in 2017, but now she is hoping to make it more like 14ft (pictured in November 2017)

He was sentenced to three days in jail and a year of summary probation, on the condition that he stays away from her home.

The Bad Blood singer was not home at the time of the incident.

Taylor's $25million property - purchased back in 2015 - is considered a historic property built in 1934, meaning it's especially difficult to get planning permission at the home.

In 2016, she went to extreme lengths to renovate the 70-year-old home, which had originally gone on sale for $39 million.

In January 2017, Taylor applied to the Beverly Hills' Cultural Heritage Commission to have the home designated a Local Historic Landmark.

And even though the designation brings with it a huge tax break - given by the city in exchange for maintenance or restorations to such properties - it also brings constraints on changes or alternations.

Previously Taylor obtained permits to put up a 6.5ft tall cinder block wall by her front porch and a 7ft high retaining wall by her tennis court.

It is understood that the application was approved because it does not impact the 'integrity' of the property.

At the time, she also upgraded and remodeled her front gate.

Idyllic: Taylor's new home was built by the movie magnate Samuel Goldwyn himself in 1934

Known as the Samuel Goldwyn Estate, her new home was first listed for $24million in 2008, and came back onto the market for an eye-watering $3million following the death of the mogul's son Samuel Goldwyn Jr in 2015.

It was built by the movie magnate himself back in 1934.

As well as its historical value, there are plenty other attractive features to the property, which sits on almost two acres of prime real estate, that doubtlessly caught Taylor's eye

It came with a main house just shy of 11,000-square-feet main house with six bedrooms and at least five bathrooms.

It also gas a two room guest apartment above the garage.

There are also spectacular gardens, a swimming pool and even a pool house with kitchenette.

Taylor can also unleash her inner Margaret Court by playing on the sunken tennis court, or even grab a pair of binoculars and spy on guests having a game from the mansion above.

The singer, who has an estimated net worth of $250 million, is said to have a property portfolio worth more than $70 million, including homes in Nashville, another house in Beverly Hills and a New York penthouse previously owned by Lord of the Rings director Peter Jackson.

Samuel Goldwyn, who changed his surname from Goldifsh, is one of Hollywood's greatest executives.

Taylor has an extensive property portfolio, including a Rhode Island home, two homes in Nashville, Tennessee and another property in Beverly Hills.
