If you look at photos of the Cape Romano dome house from the early 1980s, it looks like something straight out of a vintage sci-fi flick or maybe a high-end colony on a desert planet. Six interconnected white domes stood proudly on the white sands of Marco Island, Florida. They were sleek. They were futuristic. Honestly, they were a total middle finger to the boring, square architecture of the era. But if you hop on a boat today and head out to the tip of the island, you won’t find a house on a beach. You’ll find a cluster of graffiti-covered concrete skeletons rising out of the Gulf of Mexico like some post-apocalyptic monument.
The ocean literally swallowed them.
It wasn't a sudden disaster or a freak cinematic tidal wave that did it. It was just the slow, grinding reality of coastal erosion and a series of hurricanes that didn't care about a retired oil producer’s dream home. This isn't just a story about a cool building; it's a cautionary tale about what happens when human ego meets the shifting sands of the Florida coastline.
Who Actually Built the Cape Romano Dome House?
Bob Lee was the guy behind the vision. He wasn't some eccentric architect looking for fame; he was a retired oil producer who happened to be incredibly handy and a bit obsessed with energy efficiency. In 1980, he started construction on what would become his vacation home. He didn't just hire a crew and walk away. He actually built a prototype on his property in Gatlinburg, Tennessee, first. That one is still there, by the way. It’s a weird little trivia point—the "sister" house survived because it wasn't sitting on a barrier island in a hurricane path.
The Florida version was finished in 1982. It was a self-sustaining marvel. Lee designed the domes with a specific pitch so that rainwater would slide down into a gutter system, funneling into a massive 30,000-gallon cistern. This water was filtered and used for everything in the house. The domes were made of thick concrete and sand, meant to be aerodynamic. The idea was that wind would wrap around the structures instead of pushing against flat walls.
For a few years, it worked. The Lee family lived there, enjoying a 2,400-square-foot space that felt like living in a bubble. It had light, it had views, and it had total privacy. But the thing about barrier islands is that they aren't permanent. They move.

The Slow Descent Into the Gulf
By the early 90s, the shoreline was already creeping closer. The Lee family sold the house in 1984, then bought it back later, but by the time a guy named John Tosto bought it in 2005, the writing was on the wall. Or rather, the water was at the door. Tosto had big plans to renovate the Cape Romano dome house and move it further inland, but the permit process was a bureaucratic nightmare. Local authorities weren't exactly thrilled about a massive concrete project in a sensitive coastal area.
Then Hurricane Wilma hit.
Wilma didn't knock the domes down, but she absolutely gutted the beach. The sand beneath the foundations started to vanish. Suddenly, the house wasn't "on the beach" anymore—it was basically in the surf.
Why the Domes Didn't Just Collapse
Concrete is heavy. The foundations of these domes were driven deep, which is why they didn't just wash away like a wooden shack would have. They stayed upright, but they were now islands. Imagine trying to live in a house where you have to take a boat to get to your front door, and your front yard is a shark habitat. It became a legal mess. Fines piled up. The Department of Environmental Protection and Collier County officials got involved. There were orders to demolish the structures, but who was going to pay for it? Removing tons of concrete from the water is an expensive, logistical headache.
So, they sat. And they became a local landmark.

If you go there now—or what’s left of it—you’ll see that the Cape Romano dome house has become a canvas. People boat out there to spray paint the concrete. It’s a eerie, beautiful sight. Birds use the tops of the domes as perches. Fish hide in the submerged debris. It’s become an accidental artificial reef.
But it’s also dangerous.
Hurricane Ian in 2022 was basically the final blow for several of the structures. Before Ian, there were still several domes standing above the waterline. After the storm passed, only two were visible, and even those were partially submerged and heavily damaged. The Gulf of Mexico is a patient predator. It has been slowly digesting these buildings for forty years, and it's almost finished.
What Most People Get Wrong About the Domes
A lot of people think these were part of some secret government project or a cult commune. I've heard rumors about everything from UFO landing pads to high-tech research labs. The reality is much more "suburban Florida" than that. It was just a guy who liked domes.
- Fact Check: They weren't built by NASA.
- Fact Check: No one died in a tragic drowning inside the house.
- Fact Check: It wasn't abandoned because of ghosts; it was abandoned because the taxes were high and the land literally disappeared.
The complexity of the situation is really about property rights vs. environmental reality. When the land beneath your house vanishes, do you still own the air where the house used to be? In Florida, once land is submerged by the tide, it often becomes state-owned "sovereign submerged lands." This created a massive legal gray area that basically ensured the domes would rot in place rather than being moved or saved.

The Lessons of Cape Romano
We talk a lot about "resilient architecture" these days. The Cape Romano dome house was actually ahead of its time in that regard. Bob Lee’s use of solar power and rainwater harvesting is exactly what modern eco-homes strive for. But he missed the biggest variable: the geology of the Ten Thousand Islands.
This area is a shifting jigsaw puzzle of mangroves and sandbars. Trying to build a permanent, heavy concrete structure here is like trying to build a skyscraper on a treadmill. You might have the strongest building in the world, but if the ground is moving backward at three feet a year, you’re eventually going to end up in the drink.
The Current State of the Site
As of 2026, the ruins are mostly underwater. Depending on the tide, you might see the rounded tops of the remaining domes poking through the waves. They are no longer a "house." They are a reef. Local charter boat captains still take tourists out there, but you can’t get close safely. The concrete is jagged, the rebar is rusted and sharp, and the currents around the structures can be surprisingly strong.
How to Actually See the Cape Romano Dome House Today
If you’re planning a trip to see what’s left, don't expect to walk on the beach. You need a boat or a jet ski. Most people depart from Goodland or Marco Island. It’s a short trip, maybe 20 to 30 minutes depending on your engine and the weather.
- Go at low tide. This is the only way you'll see the scale of what's left. At high tide, they look like weird rocks.
- Hire a guide. The waters in the Ten Thousand Islands are notoriously shallow. If you don't know the channels, you will get stuck on a mudflat.
- Bring a drone. Honestly, the best views of the domes are from the air. You can see the circular footprints of the sunken domes beneath the turquoise water.
- Respect the birds. The ruins are now a major nesting site for local seabirds. Don't be that person who flies a drone three feet away from a nesting pelican.
The Cape Romano dome house is a reminder that nature always has the last word. We can build with the best concrete and the most clever designs, but we’re ultimately just guests on the coast. The domes are a beautiful, haunting mistake. They represent a future that never quite arrived—or perhaps a future that we weren't ready to build on such shaky ground.
Actionable Next Steps for Enthusiasts
If you are fascinated by the intersection of architecture and coastal erosion, your next step shouldn't just be a boat tour. Start by researching the Ten Thousand Islands National Wildlife Refuge to understand the specific ecosystem that claimed the domes. If you're an architecture buff, look into the monolithic dome movement which actually has a surprisingly large following today for storm-resistant housing in inland areas. For those visiting Florida, check local marine weather reports and tide charts via the NOAA Tides and Currents portal before heading out to the Cape Romano site; navigating these waters during a king tide or a storm surge is genuinely dangerous for inexperienced boaters. Finally, if you want to see the original "blueprint," you can still find photos and satellite imagery of the Gatlinburg Dome House, which remains the best way to see what Bob Lee’s vision looked like before the salt water took over.
