Robin Williams' Napa Valley estate finally sells for $18m... almost half the $35m the actor wanted for it two years before his death

Robin Williams' enormous Napa Valley estate has finally sold for $18.1million.

The 640-acre Villa Sorriso - or 'Villa of Smiles' - was originally up for sale at $35million in 2012, before the comedy legend slashed the price to $30million just months before his death.

The 63-year-old actor had put the home on the market months before his August 11 suicide, saying he could no longer afford the sprawling mansion in the middle of California wine country.

The price fell to $25million following his death, before being relisted again at $22.9million, until it finally sold at almost half its original price-tag.

The 20,000 square feet manion features a and bell tower, a billiards room, an oak-paneled library, a 12-seat home theater and three safe rooms, with elevators to all three three floors.

The Hook actor had the home built to his requirements in 2003, and images of the property provided a rare look inside the star's private world.

Featuring a staggering 20,000-square-foot five bedroom, six full and five half bathrooms main house and a four bedroom guest house, the 'ranch' as Robin called it, had provided a hideaway from Hollywood for the star.

While at first glance it looked like any other mansion with its blend of understated furnishings coupled with antiques, on closer inspections Robin's touches can be seen everywhere.

The Portuguese limestone house's study was clearly where the Mrs. Doubtfire star retreated to read and rest.

Away from it all: The estate is more than 650 acres and has a winery and extensive views of the surrounding Sugarloaf Ridge State Park

The built-in book case is filled with objects to inspire the comedian and thinker, including a hand carved chessboard, antiques and sculptures from around the world, and an extensive book collection.

Arranged into genres such as art, travel, film and wine, his library includes everything from comedic encyclopedia Laughing Matters, The Curse of Lono by Hunter S. Thompson, the thought provoking Salman Rushdie's The Moor's Last Sigh and celebrity profiles in Show and Tell by John Lahr.

But just like the comedian himself, with every deep thought came a laugh, and alongside the books the iconic actor also kept his Hollywood figurine collection.

Just like him: The intimate space includes both thought provoking tomes and funny Hollywood figurines, allowing the space to be both serious and silly at the same time

A child at heart - Robin even named his daughter Zelda after a computer game character - the actor collected figurines of some of Hollywood's most legendary characters and actors including Marilyn Monroe, Frankenstein's monster, Jaws and Disney's rendition of Captain Hook - the character he famously faced off against in the live action retelling of Peter Pan.

Outside in the property's sprawling grounds, which features a winery and extensive views of the surrounding Sugarloaf Ridge State Park, Robin's playful side is also evident with giant plastic retro 'cowboy and Indian' action figures scattered around.

The life-sized bright red and blue figures are hard to miss against the luscious green landscaping and vineyard which produces Cabernet Sauvignon, Merlot and Cabernet Franc varietals.

The large property also features a stunning infinity pool abutting the main house that is an amazing 65 feet long.

Also contained within the grounds is a seven-stall horse barn, tennis court, hiking and riding trails, a spring-fed pond, and, more than 100 olive trees which produces gallons of olive oil every year.

While beautiful, the home was a strange choice for the star whom had struggled with alcoholism previously.

Not only does the Villa produce various wine varieties but it also has a wine cellar, which was fully stocked with its own reds during the home's photo shoot.

Williams admitted in the month before his death his battle to stay solvent was the reason behind the sale.

He told Parade Magazine: 'There are bills to pay. My life has downsized, in a good way. I'm selling the ranch up in Napa. I just can't afford it anymore.

Little surprises: Hidden through the home is comical elements that giveaway who its owner was

'Divorce is expensive, I used to joke they were going to call it ''all the money,'' but they changed it to ''alimony.'' It's ripping your heart out through your wallet. Are things good with my exes? Yes. But do I need that lifestyle? No.' 

The actor was found dead around lunchtime on August 11, 2014 after taking his own life after battling with depression and coming to terms with a diagnosis of Parkinson's Disease. He was 63.

Family minded: The 63-year-old had three adult children - Zach, Zelda and Cody - and the home ensures that it was able to cater for big family holiday dinners
