Guy Sebastian renovates his controversial concrete Maroubra mansion that infuriated locals AGAIN – and the neighbour he famously feuded with has a very intriguing theory why

Guy Sebastian is having more work done on his controversial concrete Maroubra mansion, which was at the center of an epic neighborhood feud earlier this year.

Scaffolding has mysteriously appeared on the upper deck of the property in Sydney’s eastern suburbs.

The singer started building his dream home in 2016 and has reportedly spent $5 million on renovations so far.

Construction of the sprawling path dubbed “Fort Guy” led to an ugly lawsuit between Sebastian and his neighbor in January.

New photos, obtained exclusively by Ny Breaking Australia, show metal scaffolding and platforms wrapping around the second floor.

A worker’s walkway and metal ladders have been installed at the front of the house so that work can be done around the roof of the enormous residence.

The neighbor with whom Sebastian waged war through alleged threats, an arrest warrant, and a police arrest until everything was dismissed has an intriguing theory about what’s going on in “Fort Guy.”

Phillip Hanslow, a retired builder, told Ny Breaking Australia that Sebastian’s house “leaks constantly and it’s driving him crazy.”

He thinks the house is leaking because the “wind comes straight from the ocean” and the water is drifting up through narrow openings in the house where the roof meets the walls.

“There are problems with leaks all the time and the problem is that it’s not a house, he actually built a factory,” he said.

Mr Hanslow gave a detailed explanation of why he believes the design of the house is causing it to leak, claiming it cannot be repaired unless certain measures are taken.

Sebastian’s feud with 67-year-old Hanslow made headlines in January when long-running tensions culminated in a public confrontation.

Mr Hanslow was charged with stalking with intent to cause bodily harm to the musician following an altercation at the fence line of their neighboring properties in one of Maroubra’s main streets.

The alleged heated altercation was reportedly recorded on Sebastian’s CCTV cameras.

Police issued an arrest warrant for Hanslow for Sebastian’s protection, banning him from contacting The Choir singer or entering his property.

The case went to Waverley Local Court, where Mr Hanslow appeared accompanied by his terminally ill wife, Carole, who was in a wheelchair with an oxygen tank.

In April, the charges were dropped after video evidence was unavailable to solve the case the two men’s conflicting versions of events.

Hanslow said Friday that while he still didn’t like Sebastian, he believed the singer had been “ripped off” with the home’s “factory” design.

“It’s a shame because it’s a nice big piece of land, something nice could have been built on it,” he said.

“I’m told he’s really tired of it here because of the leak. I think I know what it needs.”

“If only he had built something conventional, but there is no disaster,” he added.

‘He spent a fortune and he had to micro-pile the building because of the weight of the building – which is drilling into sandstone and going through that is concrete and steel.

‘Because of the heavy weight of the walls he has to stop the movement, when instead he could have built into the sand and kept the height down.’

Mr Hanslow claimed there was ‘something structurally wrong’ with the house because it was ‘made up of 12 tonne sections, and where they meet is leaking’.

“To keep the wind (from the ocean) from pushing the water up, you have to line it with plastic and put whatever fibro shiplap it has over the plastic,” he explained.

But he said the latest attempt to build a jetty was certainly not the first. “They must have made at least ten attempts to fix the leaks,” he added.

Hanslow’s bitter feud with Sebastian first started in 2013 when the former Australian Idol star and wife Jules Egan, 44, bought the Maroubra estate for $3.1 million.

Mr Hanslow said a former gas company CEO had lived there in “a very nice house”, which the Sebastians demolished to build their sprawling new dream home.

Sebastian’s feud with 67-year-old Hanslow made headlines in January when long-running tensions culminated in a public confrontation. Mr Hanslow was charged with stalking with intent to cause bodily harm to the musician following an altercation on the fence line of their neighboring properties in one of Maroubra’s main streets.

The demolition sparked the feud, with Mr Hanslow claiming debris damaged his home when a ‘stone rocket’ crashed into an external wall, narrowly missing his living room window and Carole, who was watching TV.

He called the final design of Sebastian’s new house an ugly fortress because of the imposing, windowless facade, which reached the edge of his house.

In mobile phone footage of the famous stoush between the two neighbours, which emerged after the court case ended earlier this year, the Battle Scars singer confronts Mr Hanslow and accuses him of damaging the demolished fence between their properties.

Mr Hanslow replies: ‘Go fuck yourself’ and Sebastian points to a CCTV camera above the pair, which the court later heard was not working at the time.

“Yeah, aren’t you good,” Mr. Hanslow says to Sebastian, “you’re so damn worried about everyone that you have cameras everywhere because everyone hates your guts.”

When the lawsuit was ultimately dismissed in April, Guy Sebastian admitted he “regretted” the dispute and said, “I can’t keep fighting that anymore.”

Mr Hanslow said he and his wife Carole no longer live in their Maroubra home next door to the Sebastians, preferring to stay at their other property in Sydney’s southern suburbs.

Ny Breaking Australia has contacted Guy Sebastian’s agent asking for his response about the scaffolding at Maroubra’s home.
