Monaco's $2BN Expansion into the Sea Monaco, the richest country in the
world, has a problem. It’s full. The entire country covers an area smaller
than Central Park and with Monaco’s reputation for glamor and elegance, luxury developments
have literally filled up the entire country. So, in this video, we’re diving into Monaco’s
incredible solution. A $2 billion expansion that the country is building into the
sea. This is a brand new neighborhood, built by world renowned architects,
using sustainable construction techniques and offering the highest possible
quality of luxury to its residents. I’m Regis and this is Mareterra. The Story of Monaco Before we dive into Mareterra itself, it’s important to understand why Monaco
needs to expand in the first place. To do that, we need to step back
in time for a minute. To the 1800s. At that time, the Principality of Monaco
was a lot bigger than it is today. But with France to the north, Italy
to the East, and Spain not far away, the Principality had fallen under the rule of
its more powerful neighbours for centuries. That all changed, however, in 1861, when this man, Prince Charles III, signed the
first Franco-Monégasque Treaty. In it, he basically sold 90% of Monaco’s land to France. The return - 4 million
gold francs… and full independence. This is a massive simplification but the point
is that Monaco now had the freedom to really determine its own future. With the slight problem
that they’d just lost most of their territory. And that’s when the Monaco we know today was born. Monaco then used the 4 million gold francs from
France to reinvent itself as a luxury tourist destination. Focusing on glamorous coastal
resorts and gambling, which was illegal in France at the time, Monaco began attracting
Europe’s richest elite to its tiny shores. As the years went by, Monaco doubled down on
the strategy. They built casinos and luxury hotels and opened marinas to cater for the
international yachting community. In 1950, they featured in the first ever
Formula One World Championship, which still returns every year
for the Monaco Grand Prix. And with other exclusive events
like the Monaco Yacht Show and the Monte-Carlo Masters on the calendar, not
to mention the finest restaurants and shops, the country became a prime destination
for the world’s wealthiest people. To encourage them to stay, Monaco put in
place an extremely lenient tax system. Residents in Monaco pay no tax on personal
income, capital gains or wealth. Corporation tax is low and property tax is only applied
for rentals. There are, of course, a few exceptions to the rules, like if you’re a French
national, in which case you do pay income tax. Sounds good, right? Well, for them it is. And their plan worked. Monaco is now the richest country per capita in
the world. It has the highest concentration of millionaires and an international reputation
as a playground for the rich and famous. Developers have built everywhere they can in
an attempt to meet the demand for high-end real estate, but the natural geography of the
microstate limits construction massively. Much of Monaco’s 2km2 is mountainous and
difficult or impossible to build on. Despite the challenges, over 36,000 people
now live in Monaco, making it the most densely populated country in the world, and that’s only
expected to rise going into the 2030s and 40s. Since, if you want to profit from Monaco’s lenient
tax laws one needs to establish residence in the country. And an essential requirement for
that is to own or at least rent a property. Hence it is no surprise that property prices
are currently among the highest in the world. Recent valuations put the average
price of 1m2 at a crazy €50,000. To put that in perspective, that is
four times higher than in Paris. Anyway, we’re telling you all this to explain one
critical point. Monaco needs to build more luxury real estate so it can keep attracting high
net worth individuals. That’s what they do. Previous Land Reclamation So the question is, how are they doing it? Well, the only way they can. By
building out into the ocean. This is something that Monaco’s
been doing for over a century. In the years following the Franco-Monégasque
Treaty that we talked about earlier, Monaco was already filling in parts of its
coastline to build railways. Since then, Monaco has grown and grown and grown. Actually, the country has already increased its territory
by a fifth thanks to land reclamation projects. The biggest of which is the Fontvieille project
of the 1970s. Here, Monaco reclaimed 22 hectares of land from the sea using a construction method
similar in principle to the one used in Mareterra. Developers first built a 1km dike in the sea
stretching all the way around the perimeter of the new district. Then they filled the enclosure
with 7 million tonnes of boulders and gravel and after 10 years they eventually had the foundations
on which they could start laying down buildings. Fontvielle was a massive project
and a success at the same time, as it is now home to around 10% of the population. But Monaco’s new undertaking, though smaller
in physical size, is much more ambitious. Constructon of Mareterra Which finally brings us to Mareterra itself. The answer to Monaco’s lack of space
and thirst for high-end real estate. Mareterra is a 6 hectare expansion that fuses
extreme luxury with pioneering sustainable construction, and it's this combination
that makes Mareterra so ambitious. You see, every centimeter of Mareterra has been carefully master-planned. And
it starts with the foundations. Based on the principles of marine
eco-design, Mareterra’s underwater foundations have been designed to encourage
and preserve biodiversity. This kind of construction is brand new for Monaco and
before a single rock was even put down, 520m2 of sea grass was carefully transplanted to a
new home nearby, preserving its role in the local ecosystem. 12 separate cleaning operations
took place to care for protected species and 2 artificial reefs were built off shore to
provide new homes for any displaced sealife. With the ground clear, 50m underwater, Mareterra
began to take shape. It started as a wall of 1 and a half million tonnes of gravel. Each rock,
measuring between 2 and 18 cm, was placed on the seabed with pinpoint accuracy by this ship,
the Simon Stevin, kind of like a 3D printer. It formed a perfectly level foundation that
follows the natural flow of the underwater currents, putting less pressure
on the foundations and causing as little disturbance as possible
to marine life in the long-term. With the wall built, 18 of these
especially designed concrete caissons, each weighing 10,000 tonnes, were
floated in and layed perfectly on top of the rocks. Installed
from both sides simultaneously, the engineering was so accurate that the final
piece slotted in with centimetre accuracy. The caissons are weighed down with sand to hold
them in place, but each block also contains hollow parts to provide new homes for marine life.
The multi-textured finish of the caisson walls encourages algae growth and provides
shelter for fish and molluscs. The idea being for the natural world to adapt to
the new coastline as easily as possible. As project director Guy
Thomas Levy-Soussan explained: “We brought in leading experts to design
homes for people… But at the same time we brought in experts to develop reefs and
homes for the surrounding marine life, too.” This is one of the reasons Mareterra stands out
from the other previous land reclamation projects. Monaco’s newest neighborhood is pitching
itself as an eco-village for the wealthy, a neighborhood that’s in touch with the
nature surrounding it. In fact, the name Mareterra itself is actually a combination of the
Italian words for sea - mare - and land - terra. For complicated projects like this one,

this video. And now back to Mareterra. With the caisson belt in place, water was drained
out of the enclosure to be replaced by quarry materials as a base. Buildings started to go down
and at the time of this video, just 9 years since the underwater construction started, Mareterra is
months away from completion. In fact, the whole project is 8 months ahead of schedule, something
we have never said on this channel before We’ve got to admit, it’s pretty impressive. Even though construction has been really
quick, the attention to detail has stayed consistent. And above ground, the focus
on nature as well as luxury has continued. You see, Mareterra is going to be
the greenest district in Monaco. Nearly half of the entire neighborhood will
be green space, with 800 trees and a huge variety of native Mediterranean plants.
Residential areas will flow into parks, promenades and plazas, and most of the
parking will be hidden underground, making Mareterra largely pedestrian. Parts of the
new neighborhood have even been topographically designed, creating a so-called “valley” where the
public can escape from the city and be in nature. When it’s finished, these public green spaces will
be the defining feature of Mareterra for visitors But hidden amongst them, are the
buildings that ultimately make the entire project viable. These are some of
the most luxurious residences Monaco has ever seen, designed by the finest
architects from around the world. Once finished, there’ll be over 100 apartments
and 4 townhouses, as well as 10 villas, each of which has been uniquely designed
by the buyers and their bespoke architects. Architectural Flagship: Le Renzo But above all, the flagship
architectural piece is this, Le Renzo. Named after its designer, the
Italian architect Renzo Piano, the residential building is meant
to blend Monaco’s past and present. “Lasting architecture always tells an engaging
story”, Piano told Architectural Digest in 2022. “A home, for example, is not just a roof or
a shelter. Rather, it’s a dialogue between those who live there now and the moments
that shaped the land before they arrived” He’s talking about Monaco's
history as a sleepy fishing village. Le Renzo is supposed to
look like a giant sailing boat, propped up on stilts to seem like it's floating
and so as not to block the view of the ocean. Inside, the apartments all
stretch through the building, meaning residents have views of the
ocean on one side and the city on the other. The smallest apartments are a crazy
370m2, meaning there are only 2 per floor, but that hasn’t stopped some people buying
adjacent units to combine into even bigger homes. The photos look insane but they
don’t tell the whole story. Le Renzo is also sticking to Mareterra’s
ecological goals. In keeping with the eco-design, the entire building
is heated and cooled by seawater. It uses a state-of-the-art energy conversion
system known as a “thalasso-thermal loop” to control its temperature and heat its pool. The system “transforms the thermal energy of
the sea into heat or air conditioning”. It’s pretty complicated but basically seawater
is pumped into the building, passed through heat pumps which convert its thermal energy
into heating and air conditioning. Then it is returned to the ocean with no adverse
effects on marine life or water quality. The crazy thing is that this system isn’t just limited to Le Renzo. It’s actually part of a
bigger installation that will heat and cool all the properties in Mareterra and even
extend into the neighboring Larvotto district. The designers go as far as to
claim that this system alone will reduce Monaco’s greenhouse gas emissions by 7%! Sounds
good, but right now that's just a prediction. This isn’t the first time a system
like this has been used in Monaco, but Mareterra has been custom designed
with the thalasso-thermal loop in mind, making it much more efficient than
retrofitting it to older buildings. So what will Mareterra cost? What will Mareterra cost? As you might have guessed, all the properties
in Mareterra have been sold out for months. The exact cost has been kept quiet but resale
prices are already coming in at 100,000€/m2. At that price, Mareterra takes the title
of most expensive real estate in the world. Putting the cost of the smallest
apartments in Le Renzo at $37 million and the 3000m2 villas as high as €300 million! The prices are crazy, but that’s what Mareterra
is going for. Insane levels of luxury. And considering every property was sold before they
were even finished, it seems like it's working. The reality is that the value of residential
real estate in Monaco has risen by 60% over the last decade. Investors see an opportunity, as
well as a status symbol. As do the developers. Who is backing it? Which brings us to our last
point - Who’s backing it? But before that, we want to thank you for
your continued support here on MegaBuilds. If you enjoy these videos, make sure to
subscribe. This helps us a lot! Thank you. Mareterra is a response to Monaco’s need for
land but also the business interests of those behind the project. The entire $2 billion budget
comes from 9 exceptionally wealthy families, 3 from Monaco and 6 from other European
countries. Every new resident in Mareterra has been personally approved by the project
directors, showing just how exclusive the new neighborhood is but also how much
power the developers have in its final image. Mareterra is a necessity but that's
because it’s mainly a business opportunity. And whilst Mareterra is being very vocal
about its environmental credentials, it might also be fair to say that the most
ecologically responsible decision would simply have been to never build the district in the first
place. We’re not judging one way or the other, and we haven’t seen any extensive
assessments of the whole project, but it’s just important to point out
that there are two sides to the coin. One thing’s for sure though. Mareterra
cements Monaco’s position as the pinnacle of luxury. It provides much needed
land and accommodation as well as investment opportunities for the
country’s ultra-rich clientele. But what do you think? Are the apartments worth the crazy price tag? Let us
know down in the comments. We’ll be back next week with
another video. So until then, thanks for watching and see you in the next one.
