The week's hottest real estate listings, ranked by climate risk.

Glued to real estate posts on The New York Times, The Wall Street Journal, Dwell, Spaces, The Modern House, or Architectural Digest and wondering how those gorgeous homes will hold up in the next decades? I have you covered.
Heatmap has partnered with my new climate risk platform, Habitable. Every week, we add a climate risk score to the real estate listings featured in the news and ask: Could you live here as the climate changes?
Using a model developed by a team of Berkeley data scientists at Climate Check, Habitable scores each property for heat, flood, drought, and fire risk on a scale of 1-10. One represents the lowest risk and 10 is the highest. Our rating for each hazard is based on climate change projections through 2050. (You can check your own home’s climate risk here.)
For today’s edition, I apply the Habitable Index to the many midcentury homes coming on the market for the first time ever. Read on and find out out which of these mid-century homes will prove most climate resilient, from best to worst.

This John Marsh Davis spectacular hillside mid-century house is worth snapping up. On the market for the first time since the original owners (and architect) built it, the house allows for indoor-outdoor living at scale. What’s more, this property should be intact until the next mid-century. Its climate risk is low, with no flood risk and only moderate drought, heat, and fire risk. Race you to Kentfield.
Featured in WSJ and listed for just under $5 million.

In Bellevue, Nebraska, the “Flying Nun House” just went to auction and could very well have sold by the time we publish. This wholly original home is a time capsule seemingly untouched since it was built and decorated in the 1970s. And no need to worry about that pristine shag rug flooding either; there is little if any climate risk other than the high heat typical for the region. Nebraska here we come!
Featured on @zillowgonewild and listed for $695,000.

This Habitable house on the Tred Avon River in Marlyand is built to withstand whatever the environment plans to throw at it. Yes, it’s on a river but the house sits 18 feet above the mean high water level. With geothermal heating systems and concrete rain screens and a dock with power lifts with water deep enough to accommodate sailboats, this house is climate ready. Forget Nebraska, race you to Maryland.
Featured on @list.modern for just under $4 million.

With spectacular views over San Francisco Bay in Oakland, this mid-century house on a hilltop surrounded by oak trees and horse trails is on the market for the first time in 67 years. The climate risk is minimal for flood and heat, but the fire and drought risk is something worth considering.
Featured in Dwell and listed for $2.9 million.

This mid-century modern home sits on its own private rock island and connects to the trails of Starboard Rock Sanctuary overlooking Acadia National Park in Maine. And while it’s not the worst flood risk we’ve seen, the 7/10 score still may force you onboard an actual boat soon enough.
Featured on @TheCreativesAgent and listed for $1.7 million.

This amazing modernist California home was part of a 1950s housing cooperative in Los Angeles. It has been restored by architectural preservationist HabHouse and is now for sale.
With concrete and the amazing carport, the house is fairly fire proof which is helpful considering the 8/10 fire risk. Floods and heat won’t be a problem, but like much of LA, the drought risk will make life here a bit parched. Porsche not included.
Featured on @TheCreativesAgent and listed for just over $4.1 million.

A design marvel built in 1952 by architect Bertrand Goldberg who designed Chicago’s Marina City is for sale. Combining plywood, a massive stone fireplace, and floor-to-ceiling windows with full-scale views across the Long Island Sound, it’s a one of a kind home. Shame about the location, though, because this historic structure has a 10/10 risk of flooding. It will be sad to see this beauty swallowed by the sea.

The spinoff of Lawrence Livermore National Lab has a new 10-point plan to get onto the grid by the 2030s.
One of fusion energy’s newest startups, Inertia Enterprises, is betting that the fastest route to commercial fusion runs through one of the field’s oldest ideas. The company, which raised a $450 million Series A earlier this year, plans to build a power plant based on the laser-driven fusion system pioneered at Lawrence Livermore National Laboratory’s — the only tech yet to have produced more energy from a fusion reaction than it took to initiate it. Now, Inertia has shared its commercialization roadmap exclusively with Heatmap, detailing the 10 near-term capabilities it must demonstrate before this landmark experiment can become a grid-scale power plant by the mid-2030s.
The roadmap offers a route from the national lab’s impressive but commercially impractical fusion demonstrations to an economical power plant capable of producing electricity for the grid. At its core are a set of milestones — mostly aimed at developing cheap, mass-manufacturable components — that Inertia says it must clear before those individual systems can be integrated into a working plant. This road is not necessarily linear, however, as various teams will likely be working on many of these goals simultaneously.
At least the physics of Inertia’s approach are already proven, the startup’s CEO Jeff Lawson told me, pointing to the fusion experiments at Lawrence Livermore’s National Ignition Facility as a proof-of-concept. The lab’s demonstration of net energy gain caps more than six decades and $30 billion (in 2026 dollars) of U.S. fusion research. The remaining challenges, he argued, are all engineering-related, requiring “elbow grease, hard work, and smart people” rather than breakthroughs in fusion science.
"It seems to us like a startup or a commercial company of any variety should be focused on commercializing a proven scientific result, as opposed to actually trying to demonstrate the basic science to begin with," Lawson told me. Basic science, he argues, is better left to national labs and universities, where researchers can pursue "unbounded problems" that don’t align with the expectations and timelines of venture-backed startups.
Indeed, no fusion startup has yet achieved scientific breakeven, the milestone Lawrence Livermore first hit in 2022, and has since repeated numerous times. But leading players such as Commonwealth Fusion Systems and Helion Energy maintain that it’s only a matter of time before they validate the physics behind their own reactor designs, which they claim will be highly cost-competitive.
Lawson, on the other hand, readily acknowledged that Lawrence Livermore’s tech is uneconomical in its current form. His bet is simply that the more predictable path to a commercial reactor is to drive down the cost of the lab’s validated fusion approach, known as inertial confinement. This system relies on high-powered lasers firing at a millimeter-scale pellet of fusion fuel, compressing it to extreme temperatures and pressures until the atoms fuse. Today, the National Ignition Facility makes each individual fusion target by hand, a workable solution given that it only uses about a dozen per year.
That production model, however, isn’t remotely plausible for a grid-scale power plant. Because each fusion reaction lasts just a fraction of a billionth of a second, a commercial facility must fire its lasers at a fresh target about 10 times per second to generate continuous electricity — requiring the production of hundreds of millions of targets each year.
Scaling production to roughly a million pellets per day and making them inexpensive enough for commercial operation without compromising the strength or precision required for fusion ignition is central to Inertia’s roadmap. That includes goals five, seven, eight and nine — industrializing the manufacturing of the carbon shells that hold the fusion fuel, making the thin films that hold those carbon shells both durable and cheap, scaling up and automating fusion target assembly, and speeding up how fast targets are filled with the requisite deuterium-tritium fuel.
The other central focus of the roadmap is the laser system, which will ultimately consist of 1,000 individual units operating in concert to compress and heat the fusion fuel. Key priorities include reducing the system’s cost (goal two), dramatically increasing its firing cadence (goal three), and bolstering its durability to withstand high-intensity operations (goal four). Goal six also complements these efforts, calling for the development of a control system capable of tracking moving fusion targets to precisely align each laser shot.
Goals one and 10 bookend the journey with some broader milestones. The first focuses on increasing the fusion target’s energy gain — the ratio of fusion energy produced to laser energy delivered — to more than 25 times ignition. Today, the National Ignition Facility’s best-performing laser shot has yielded a gain of just over four times what it took to start the reaction. Goal 10 then zooms out to the ultimate objective: integrating all these technologies into a commercially viable power plant that can deliver either electricity or industrial heat to end customers.
To reach that point, Inertia has embarked on an industrial engineering hiring spree, recruiting folks with experience taking complex hardware systems from prototype to mass production, “not unlike the processes that are used in the semiconductor or consumer electronics world,” Lawson explained. The company has been making progress on its component development goals since the beginning of the year, he told me, and expects to announce the successful demonstration of a few of these milestones in the coming months. Lawson ultimately expects Inertia to complete the core components of its laser and target manufacturing systems by the middle of next year.
The team will spend the next two to three years integrating these individual pieces into two fully operational subsystems, a prototype laser system and a target manufacturing line. Around 2030, the company will begin combining those subsystems into a first-of-a-kind fusion power plant, which will also serve as the proving ground for the target chamber, tritium fuel breeding system, and power conversion system that turns fusion heat into electricity. By the middle of the next decade, Inertia aims to be generating power from this first plant, setting the stage for the company to build and connect additional grid-scale commercial power plants.
There are plenty of engineering trade-offs that the company will have to solve for. Take the decision around how to size the target chamber, for example. “If you make it bigger, your walls have an easier time and survive longer, but it’s more expensive. If you make it smaller, your walls have a tougher time because they’re closer to all the heat and energy that the fusion reaction is creating, but now your power plant costs less to build.”
But to Lawson, this represents exactly the type of problem Inertia was built to solve: complex engineering issues that come to the fore once scientists have demonstrated the fundamental physics are sound. He thinks other fusion companies may someday reach this stage, as well — though he’s unwilling to hazard a guess on exactly what approach or startup is best positioned to do so.
“There have been generations of scientists who’ve made their predictions about fusion energy and gotten it wrong,” he told me. “I’m not going to pretend to be smarter than them. All I’m here to say is, just knowing that one did work, we can commercialize it.”
