EXCLUSIVE - 'We're in the tiniest bedroom on earth.' Not any more! $20 million actress Melissa McCarthy and husband Ben Falcone set to move into luxurious mansion with screening room, elevator and tennis court

This is the $5 million secret luxury retreat that Hollywood star Melissa McCarthy is transforming into her dream home.

The six bedroom, seven bathroom property in an exclusive enclave in Toluca Lake, California was snapped up by McCarthy and husband Ben Falcone in 2012.

And for the past few years the Spanish colonial style estate has been a labor of love for the couple as it undergoes a multi-million dollar renovation.

These exclusive photos show Bridemaids star McCarthy, Falcone, and their young family visiting the property - which is currently a building site - with a woman believed to be an interior designer.

The impressive private manse already boasts an outdoor swimming pool and indoor grotto style spa, sauna and gym, a floodlit championship tennis court, custom built BBQ area and a guest house.

But McCarthy, 45, and hubby Falcone, 42, are revamping the property with a whole range of high-end extras.

The couple have two daughters, Vivian, 8, and Georgette 'Georgie', who will be six in March. McCarthy's pregnancy with Vivian was written into the last season of Gilmore Girls. Vivian is also playing the younger version of her mom's character in the movie The Boss.

In 2013 they began filing permits to remodel the 8,656 sq ft property, which is in one acre of grounds.

Permits were filed with the City of Los Angeles Department for Building and Safety to install a brand new 46ft by 16ft swimming pool and 8ft by 8ft spa. The old pool is being filled in.

Melissa McCarthy and her husband Ben Falcone bought the Spanish Colonial from actor and songwriter Alan Thicke in 2012 for $3,525,000

The couple, who were married in 2005, are also adding a 3,000 sq ft in additions to the house including 671 sq ft to the existing screening room and are even installing an elevator

The home in Toluca Lake has six bedrooms and seven bathrooms and is close to 9,000 square feet - with more to come

The modest three bedroom home where the family are now living is on the market for $1.4 million

Melissa and Ben have kept their impending move under wraps, but Daily Mail Online can reveal the celebrity couple are spending a fortune to upgrade the $5 million home

The property was bought for $3.5 million in November, 2012 and has already jumped in value by another $1.5 million

The couple, who were married in 2005, are also adding a 3,000 sq ft in additions to the house including 671 sq ft to the existing screening room and are even installing an elevator.

The property was bought for $3.5 million in November 2012 and has already jumped in value by another $1.5 million.

But with the huge investment and extensive building work McCarthy and her husband are carrying out, that valuation will rise again significantly when the project is complete.

The new pad is less than a mile away from McCarthy’s current home which is a modest three bedroom, two bath property also in Toluca Lake. It is on the market for $1.4 million and is a fraction of the size of the new digs at 2,000 sq ft.

In an interview with Variety in June 2014, McCarthy told how her two young daughters share a room and her Mac computer is packed in the closet in the cramped house.

‘We’re in the tiniest bedroom on Earth,’ she confessed.

On the morning of the 2012 Oscars, when she was getting ready for her big night as a supporting actress nominee for her breakout role as the loudmouth sidekick in Bridesmaids, she didn’t have any space in the house to get dressed.

‘I had my stylist come to my garage,’ McCarthy says. ‘My friends are like, “Get it together.”’

But comedienne McCarthy will soon be able to spread her wings in her new dream home which is expected to be completed later this year.

Once McCarthy and her family move in they can pop in on next door neighbor Garry Marshall, the 81-year-old movie director famous for films like Pretty Woman and Frankie and Johnny.

Actress Megan Fox was also a neighbor in the exclusive celebrity enclave until recently when she sold the house she shared with Brian Austin Green for a knockdown $2.6million.

The home is clear sign of McCarthy's continued success in Hollywood.

McCarthy's breakthough role was Sookie St. James on the television series Gilmore Girls in 2000. But her real claim to fame came when she was cast as Molly Flynn on the CBS sitcom Mike & Molly. She won an Emmy Award for Outstanding Lead Actress in a comedy in 2011. She was also nominated for an Emmy as host on Saturday Night Live three times.

McCarthy's biggest movie success was in the 2011 comedy hit Bridesmaids, for which she was nominated for an Oscar for Best Supporting Actress as well as a SAG award. 

In 2015, Forbes named McCarthy the third highest-paid actress in the world.

Falcone often makes cameo appearances in movies and television shows starring McCarthy, such as "Gilmore Girls-Season 3, Episode 20", Bridesmaids, The Heat, Tammy, Identity Thief and Spy.

As well as her successful acting career McCarthy is also the founder of the production company On the Day Productions with husband Falcone.

In 2015, she received a star on the Hollywood Walk of Fame and released women's plus size clothing collection, Melissa McCarthy Seven7.

Also in 2015, Forbes named named the Illinois native the third highest-paid actress in the world that year. 

The Bridesmaids star and her husband began filing permits to remodel the 8,656 sq ft estate set on one acre 

The home has been under construction since 2013. The renovations will add a considerable sum to it current value
