The climbing cost of climate change for the Australian property market

The insurance premium gap between flood affected and non-flood affected homes is significant

Climate change is already affecting home values due to the impact of more severe weather events and rising home insurance premiums, and the cost of building is likely to rise as regulatory changes designed to enhance climate resilience alter building codes and zoning laws, according to a new report.

The National Housing Supply and Affordability Council describes climate change as an emerging trend that is raising the cost and complexity of supplying more housing. In its newly released State of the Housing System report, the council discusses how climate change is reducing the value of some homes when major weather events cause flooding or other natural disasters.

“The price differential between flood-affected and non-flood affected homes has been estimated to be up to 35 percent a year after a flooding event,” the report says. Furthermore, the RBA estimates around 7.5 percent of properties are in areas that could experience price falls of at least 5 percent due to climate change by 2050.

More than one million households are struggling to afford home insurance, and rates of non-insurance are increasing due to the cost. For example, the Australian Competition and Consumer Commission estimated that 40 percent of homes in Northern Western Australia were uninsured in 2020.

Climate change is causing home insurance premiums to rise across Australia, adding to already elevated housing costs. Homeowners in areas considered atrisk of natural disasters are expected to see insurance premiums rise further or have difficulty obtaining insurance due to heightened risks.

More frequent and severe weather events such as cyclones and bushfires, as well as coastal erosion and flooding from rising sea levels, present risks to housing safety. More than 3,000 homes were lost in the 2019-20 bushfire season, causing $2.3 billion in insurance losses. The report says the predicted direct cost of natural disasters to the economy and housing will be $35.2 billion per year by 2050.

Climate change and net-zero targets could raise the cost of building new homes, the report says. Regulatory changes to enhance climate resilience will alter building codes and zoning regulations.

Developers facing higher compliance costs may have difficulties meeting updated standards, potentially delaying or reducing housing availability.

However, the report says the increased cost of building a home with climate-resistant materials and eco-friendly features is more than offset by lower energy costs over a property’s lifetime. The current minimum energy efficiency requirements within the National Construction Code are estimated to deliver a householdlevel benefit-to-cost ratio of 1.37, according to the report.

Drew Barrymore is making an almost $8.5 million adjustment to her real estate portfolio with the listing of her home in the Hamptons.

The actress and talk show host has owned the seven-bedroom home—which has appeared across her social media platforms—since 2019, when she paid $5.5 million for it using a limited liability company for the purchase, records in PropertyShark show.

Despite its transformation into a residence, the former barn still has plenty of period charm, from soaring ceilings and exposed beams to hardwood floors.

The hub of the 6,850-square-foot, light-filled home is the great room and adjacent breakfast nook and kitchen, the latter of which is separated from the rest of the space by a wall made from window frames. Glass doors open up from the great room onto a deck.

There’s also a living room with a brick fireplace, a pink-painted dining room with a sloping ceiling and a skylight, and a den. Plus a separate one-bedroom guest house with a living room and office area, according to the listing with Kathy Konzet of Sotheby’s International Realty – East Hampton Brokerage. Konzet wasn’t immediately available to comment.

The park-like grounds, complete with flowering gardens and rolling lawns, are home to a pool, pool house, a bocce court and plenty of areas for outside entertaining.

Barrymore, 49, began her career at just 11 months old when she appeared in a dog food commercial, and at 7, she starred in 1982’s “E.T. the Extra-Terrestrial.” As an adult she’s best known for roles in “Charlie’s Angels,” “Grey Gardens,” “The Wedding Singer,”and “50 First Dates.”

Her talk show, “The Drew Barrymore Show,” debuted in 2020. A representative for the star couldn’t be reached for comment.
