Spider-man star Tom Holland will have no problem keeping in superhero shape after planners agreed to a major makeover of his £2.5 million home, including the addition of a gym.

The seven-figure renovations – funded from the estimated £15 million he has earned from his six Marvel movies – have prompted speculation that the actor’s American girlfriend Zendaya will move into the mansion with him.

Tom, 25, has until now been living with his comedian father Dominic and photographer mum Nicola – and the new property is less than a mile from their home in South-West London.

The Mail on Sunday can reveal that the star bought the three-storey, six-bedroom property in 2018 but wanted it extensively remodelled before moving in.

Once finished it will boast a cinema, sauna and games room in a new rear extension. He has also been granted permission for a bigger basement and a timber-clad garden room that overlooks landscaped grounds.

Commenting on rumours that the couple could soon be choosing furniture together, a source said: ‘Tom has spent quite some time making this house into his perfect home and Zendaya has been visiting him in London, so let’s see. They are Hollywood’s hot, young couple and don’t want to be apart.’

The couple – currently setting box office records as web-slinger Peter Parker and his love interest Michelle ‘MJ’ Jones-Watson in Spider-Man: No Way Home – were last week spotted hand-in-hand outside his parents’ home before enjoying a trip to the West End to see Harry Potter And The Cursed Child.

And yesterday our sister paper the Daily Mail reported that the couple had a secret meeting with the Duke and Duchess of Sussex.

The reason is unclear, but Harry and Meghan may have hoped to persuade the stars to take part in one of their media projects. When not filming blockbuster movies, Holland is regularly seen in local pubs with his three brothers and childhood friends.

Since buying the mansion, he has hinted that it might be time to hang up his Spider-Man costume.

Last month, he said: ‘I’ve spent the last six years being so focused on my career. I want to take a break and focus on starting a family and figuring out what I want to do outside of this world.’

Holland shot to fame playing Billy Elliot in the stage musical from 2008 until 2010. Spider-Man: No Way Home has so far taken about £1.25 billion at the box office.

It recently emerged that Tom and Zendaya’s romance almost didn’t happen after a Spider-Man producer urged them not to date.

The Spider-Man star and the Euphoria actress were reportedly advised to keep their relationship platonic by producer Amy Pascal when they were first cast in Spider-Man, according to The New York Times.

‘I took Tom and Zendaya aside, separately, when we first cast them and gave them a lecture,’ Pascal said. ‘Don’t go there — just don’t. Try not to.’

‘I gave the same advice to Andrew [Garfield] and Emma [Stone],’ the producer revealed. ‘It can just complicate things, you know? And they all ignored me.’

Garfield and Stone met on the set of the 2012 movie The Amazing Spider-Man. Rumors came out that the two were dating in 2011, and they remained together for a few years before apparently breaking up in 2015.

While their new movie is already something of a success, both stars have a number of other projects on the way as well.

The second season of Zendaya’s show Euphoria is currently airing, and she will reprise her role as Chani from Dune for the sequel which is scheduled for a 2023 release.

She is also rumored to take a part in the upcoming Francis Ford Coppola film Megalopolis alongside Cate Blanchett and Oscar Isaac.

Holland, on the other hand, will play Nathan Drake in the movie Uncharted and Fred Astaire in a biopic about the iconic actor.
