Amphibious houses are no longer a distant or futuristic idea. They're homes that can stand firm on dry land, but if the water rises, they float. Just like that. It's not magic or science fiction: it's architecture designed to coexist with a climate that increasingly brings more surprises. And if we look at the Balearic Islands, where the sea is just a stone's throw away and the rains sometimes weigh heavily, the question arises: would such a model be viable here?
When architecture observes nature
The concept itself isn't too complicated. The house rests on a fixed base, but it's designed to rise if the water level requires it. This is achieved with a floating foundation supported by vertical piles that prevent the house from shifting. The interesting thing is that we're not talking about prototypes: the Netherlands, the United Kingdom, and Canada already have such houses that work, and do so well.
The Balearic Islands and flooding: a reality that cannot be ignored
The islands have experienced difficult times in recent years. Just remember what happened in Sant Llorenç in 2018. That disaster made it clear that we are not immune to extreme events. Therefore, starting to think about housing that can withstand these types of events is not an eccentricity, but rather a necessity. However, doing it well means knowing the regulations, understanding the terrain, and being clear about what can and cannot be done.
The Coastal Law sets the limits
There's a tricky point here. The Coastal Law doesn't allow construction in the strip closest to the sea, which leaves out many areas that, at first glance, would seem ideal for this type of housing. In reality, if we're talking about applying it in the Balearic Islands, we'd have to look inland or to peri-urban areas that are prone to flooding, yes, but that aren't within what's known as the Preferential Flow Zone.
Where could they operate in Mallorca or Menorca?
These homes are designed for areas where the water rises relatively calmly, without strong currents or drag. And of course, here we have the dreaded torrents, which come with force and sweep away anything they catch. So they wouldn't work everywhere. But there are estates and private plots where flooding is slower and more predictable. In those cases, the floating system could be useful and safe.
And how much does it cost to build one?
We're not going to lie: this type of construction comes at an extra cost. Typically, between 20 and 25 % more than a conventional house. This extra is due to the type of foundation and the technical adjustments it requires. Still, when weighed against the damage that flooding can cause every few years, the difference can be worth it. Furthermore, having insurers and banks understand and support this type of housing will make a difference.
It's not about building where you shouldn't
It's important to be clear about this: just because a house floats doesn't mean it can be built anywhere. Amphibious homes aren't a no-brainer for construction in protected areas. Rather, they can be an option in places where homes already exist, but which, due to climate change, now face new risks and require realistic solutions.
What has already been done abroad can serve as a guide.
In Maasbommel, next to the Meuse River, there is a group of amphibious houses that rise when the flood hits and then return to their original position as if nothing had happened. These have also been built on the Thames, with adaptable anchors and connections. It's not just a technical issue: these homes take great care in design, energy efficiency, and, above all, safety. The Balearic Islands could take note, adapt what they've learned, and apply it while respecting their own unique reality.
Not everything is easy, but not impossible either.
It's clear that talking about amphibious homes here involves facing several challenges: permits, prices, regulations, market acceptance... but it also opens doors. We're talking about innovation, yes, but also about common sense. About how to live better in a changing environment. It's not for tomorrow, perhaps, but the time to start thinking about it has arrived.
On the islands, building has always been an exercise in balance.
From the days of stone to farmhouses and modern seaside apartments, construction in the Balearic Islands has had to adapt to the environment. Salt, wind, regulations, history… It's all part of the process. Amphibious houses aren't a departure, but rather a new way of responding intelligently to a changing landscape.
