Renovation plans are underway for Kyle Sandilands' $1.8 million holiday house on the Central Coast.

In November, the 54-year-old KIIS FM radio host snapped up the three-bedroom, two-bathroom fixer-upper in the beachside suburb of Copacobana as a holiday house with his wife, Tegan Kynaston, and their toddler, Otto.

Planning alerts reveal the couple has obtained a complying development certificate for the property, with the project set to cost $670,000.

The proposed works are for a new in-ground swimming pool and landscaping.

Architectural plans designed by Central Coast-based firm SiteDesign + Studios reveal a striking resort-style pool area.

The 10-metre pool includes a shallow "beach" area as a safe place for son Otto to take a dip, and a white rendered wall for privacy.

It appears that privacy is a key factor for Sandilands.

In addition to the privacy wall, the plans include a one-metre high vertical balustrade around the alfresco patio and planter boxes with privacy planting.

"Privacy planting surrounding the pool and privacy screens will be provided to soften the development to the neighbours," the application reads.

The alfresco area also features a white architectural concrete bench seat.

Designed with his young son in mind, the application states: "The pool has been located in a position to make it safe to access and to be visual from the house balcony to watch over children swimming".

Six trees will be removed from the site to build the pool.

Set on a 588-square metre block, the two-storey house has picturesque views of Copacabana Beach and Macmaster Headland.

The current floorplan comprises three bedrooms, three bathrooms and open-plan living spaces, including a large rumpus room on the ground level.

The property hit the market with George Brand Real Estate Avoca Beach in January 2024 with an asking price of $1.995 million.

After failing to secure a buyer after 11 months on-market, Sandilands swooped in and purchased the unrenovated house for $1.8 million.

The listing described the property as "soaked in sunlight and positioned to maximise the views" and offering "a family-focused layout with an ideal construction for future development".

Other property features include ducted air conditioning, secure gated entry and landscaped gardens.

The $1.8 million transaction is small change for cashed-up Sandilands, who, along with co-host Jackie O Henderson, signed a decade-long deal with Australian Radio Network, understood to be worth around $200 million.

Shortly after making his move into the Central Coast property market, Sandilands offloaded a luxury three-bedroom, two-bathroom holiday house in far-north Queensland for around $2.55 million in December.

The property in Port Douglas spent 109 days on-market and sold after the asking price was reduced from $2.9 million.

Sandilands paid $1.3 million for the secluded rainforest retreat in 2020 but chose to sell to find a weekender closer to Sydney.

"When it was just Tegan and I, the place was absolutely perfect for us because of its private and tropical location overlooking the water," Sandilands said.

"Our two-year-old son Otto loves the beach, which can be difficult to go to up around Port Douglas due to the crocodiles.

"We're going to relocate somewhere a bit closer to Sydney where we don't have to worry about hungry reptiles."

The couple shares a luxury home in the ritzy Sydney suburb of Vaucluse, which they purchased for $14 million in 2023.

Sandilands also owns a palatial residence on acreage at Glenorie in Sydney's Hills District, which he bought for $3 million in 2022.

Sandilands made headlines in February after announcing on-air that doctors had found an aneurysm in his brain.

He also has a chest aneurysm that will require surgery.

"I was told by my medical team, which sounds like I'm already very sick, to have a medical team, that I have a brain aneurysm and it requires immediate attention, brain surgery," he said.
