Mega-Project Plans 3,000 Apartments in Bañados De Carrasco

Bislun S.A.S., backed by Eduardo Costantini’s Consultatio and a group of undisclosed investors, is pushing forward with an ambitious plan to develop nearly 3,000 housing units across 226 hectares in Bañados de Carrasco. The project draws clear inspiration from Argentina’s Nordelta, and at $1.248 billion spread over 15 years, it’s the kind of scale Uruguay hasn’t really seen before.

That scale is exactly why it’s worth paying close attention to where things stand right now. Departmental approval hasn’t been granted, and environmental authorization is still pending , two hurdles that carry real weight in Uruguay, especially when the site sits directly alongside protected wetlands. Anyone watching this space should understand that those aren’t minor formalities here; they shape timelines, costs, and ultimately whether a project moves forward at all.

The location also raises legitimate questions that go beyond paperwork. Flood risk is a genuine concern in that corridor, and the neighboring working-class communities deserve serious consideration in how urban planning decisions get made. Uruguay has a strong tradition of balancing development with social equity, and that standard doesn’t disappear because the numbers are large.

What this proposal signals is an appetite for large-scale, master-planned residential development in Montevideo’s periphery. Whether it materializes as envisioned depends heavily on what comes out of the regulatory process. Keeping a close eye on those approvals , and the conditions attached to them , will tell you far more about this project’s real trajectory than the headline figures do.

Key Takeaways

A large-scale residential development is being proposed for Bañados de Carrasco, covering between 226 and 228 hectares near the Canelones border. The project would deliver close to 3,000 housing units, with density thoughtfully stepped down as the land approaches the wetland , 1,150 medium-density units, 1,370 medium-low, and 520 low-density homes rounding out the mix.

The total investment sits at roughly $1.248 billion, spread across a 15-year build-out. That kind of timeline is typical for developments of this scale in Uruguay, and it gives buyers and investors room to enter at different phases rather than committing all at once.

Beyond the residential component, the masterplan incorporates an eco-park, lagoons, a linear park, a school, a civic center, and vehicle bridge access , the kind of infrastructure that genuinely supports long-term property value in a self-contained neighborhood.

That said, the project still needs to clear several regulatory hurdles: a declaration of departmental interest, land recategorization, and environmental authorization are all pending. Anyone watching this closely should keep an eye on those approval stages, since each one marks a meaningful shift in the development’s viability. In Uruguay, environmental authorization near wetland zones can take time, and understanding that process is key before making any decisions tied to this project.

What Is the Bañados De Carrasco Mega-Project?

Bañados de Carrasco is one of those locations that naturally draws attention, and this mega-project reflects exactly why. Roughly 228 hectares are being developed into close to 3,000 housing units, covering a solid range of formats , low-rise buildings, grouped houses, detached homes, and chacra-style residences. That variety is deliberate and worth noting, since buyers here are not limited to the standard apartment block model that dominates so much of Montevideo’s residential market. The entire undertaking represents a $1.248 billion commitment spread across a 15-year timeline.

The scope goes well beyond housing. Commerce, offices, schools, recreational areas, and public spaces are all part of the plan, making this a full mixed-use expansion rather than a standalone residential neighborhood. Projects of this scale tend to generate their own momentum once established, and the location near the Canelones border positions it as a genuine gateway development.

That said, the site sits directly beside a significant wetland corridor, and that detail carries real weight. Bañados de Carrasco is not just scenery , it is a protected natural system that many residents, environmental groups, and public institutions actively want to preserve. The push for development and the push for wetland conservation are pulling in opposite directions here, and anyone seriously evaluating this opportunity should understand that dynamic clearly before moving forward. Knowing the land means knowing its context, and in Uruguay, that context often shapes what gets built, when, and how.

Who’s Behind the $1.248 Billion Bañados De Carrasco Plan?

Bislun S.A.S. is the name on every filing tied to this project, and that’s your starting point. The real muscle behind it runs through Eduardo Costantini and Consultatio , the same group that built Nordelta across the river in Argentina, so there’s genuine pedigree here. Uruguayan partners are part of the structure too, though their identities haven’t been made fully public yet. Notably, the project model draws directly on Nordelta, which was itself built on Argentinian wetlands.

In this market, that matters. Uruguay’s real estate framework rewards buyers who ask the right questions early, and the ownership picture here still has gaps. “Multiple investors” is the language being used, but no complete roster has come forward. That’s not unusual at this stage of a large-scale development, but it’s also not a reason to set the question aside.

What’s confirmed so far:

A $1.248 billion plan for Bañados de Carrasco is significant by any measure in this country. Before committing capital, get clarity on the full funding structure , not because the project lacks credibility, but because that information is simply part of doing this properly.

Why Is the Bañados De Carrasco Site so Large?

The 226-hectare footprint at Bañados de Carrasco isn’t just a large number on paper , it’s a direct response to what building responsibly in a wetland environment actually requires. In my years working across Montevideo’s residential and mixed-use markets, I’ve seen projects underestimate site complexity, and it rarely ends well. Here, the scale is purposeful.

The plan incorporates multiple density zones, which means housing, commercial spaces, offices, and schools each get room to breathe without competing for the same square meter. That kind of thoughtful zoning is what separates a livable development from one that feels overwhelmed by its own ambition.

Wetland buffer requirements add another layer to the equation. Developers are obligated to set aside meaningful portions of land to protect the surrounding ecosystem, and that protection isn’t optional , it’s built into the legal framework governing this type of site in Uruguay. This matters because the wetland functions as a natural regulator, retaining runoff during heavy rains and releasing it gradually to reduce downstream flood risk. Once you factor that in alongside the density zoning, the 226 hectares stop feeling excessive and start feeling like the minimum viable footprint for a project of this nature.

A 226-Hectare Footprint

When you’re looking at Montevideo’s northeastern edge, a land parcel stretching between 226 and 228 hectares tied to Bislun S.A.S. isn’t something you pass over lightly. This is Bañados de Carrasco territory , ecologically sensitive, strategically positioned, and now concentrated under a single private entity’s control. In Uruguayan real estate terms, that’s not a development footprint; that’s district-scale land consolidation, and the distinction carries real weight.

Scale like this tells you something specific about intent. A holding this size signals long-term territorial control rather than a contained construction project, and in a country where wetland-adjacent land carries both environmental and regulatory significance, that raises legitimate governance questions worth examining carefully.

A few things worth keeping in mind when evaluating a claim of this magnitude:

Assembly at this scale typically reflects a strategic position held over time, not a short-cycle development play.
Private control over wetland-adjacent land in Uruguay intersects with MVOTMA environmental frameworks in ways that deserve clear public disclosure.
Comparing this footprint to entire city districts isn’t rhetorical , it’s the accurate reference point.

Uruguay’s land registration system and transparency mechanisms exist precisely for situations like this. Buyers, neighbors, and civic stakeholders alike benefit from knowing who holds title, under what conditions, and with what long-term intentions. That information should be accessible, not buried. As of now, the project remains in what officials describe as an early stage of studies, with most specifics still undisclosed.

Multiple Density Zones Included

The 226 hectares make a lot more sense once you look at how they’re actually divided up. This isn’t a single housing typology pushed across uniform land , it’s a zoned gradient that responds directly to the terrain, and that’s exactly what you want when you’re working alongside a humedal. Medium-density zones account for 1,150 homes, medium-low areas hold 1,370, and the low-density sector , the largest portion and the one sitting closest to the wetland , covers 520 units. Each band reflects where the land allows intensity and where it doesn’t.

That relationship between density and ecological sensitivity is something buyers in Uruguay increasingly understand and value. The low-density parcels near the edge aren’t a compromise; they’re a premium. A linear park is also planned to separate the neighborhood from the wetland itself, reinforcing that boundary rather than blurring it. Anyone who’s spent time near Montevideo’s coastal wetlands or the quieter zones around Laguna del Sauce knows that proximity to that kind of landscape carries real weight , and real responsibility in how development is structured around it.

What this zoning does well is hold two very different buyer profiles on the same project without forcing either to settle. Urban density is available for those who want it. Lower intensity, more open lots near the wetland are there for those who need that distance and calm. Trying to meet both demands on a smaller footprint simply wouldn’t work , the scale here is part of what makes the balance possible.

Wetland Buffer Requirements

Working next to a wetland network of this scale , somewhere between 1,100 and 1,300 hectares , means the regulatory framework kicks in well before you break ground. The core wetland itself carries a rural natural designation, and the surrounding buffer sits under rural de interfaz, a category that limits intensive use and requires proper buffer mapping as part of the development process. These aren’t arbitrary hurdles; wetland hydrology doesn’t respect property lines, and its effects reach far beyond any single site.

Municipal conditions require developers to formally define a protection area that preserves the bañado’s matrix ambiental. In practical terms, that translates into three non-negotiable commitments:

No drainage or desiccation that would alter the wetland’s natural water regime
Maintained flood-storage capacity for heavy rainfall events
Active filtration protection to prevent urban runoff from degrading the ecosystem

Getting this mapping done early , and done correctly , saves considerable time and cost down the line. Any development proposal that skips or underestimates this step simply won’t move forward through the approval process. Uruguay’s land use framework on this is clear, and local municipalities apply it consistently.

How Will the 3,000 Housing Units Be Divided?

The 3,000 units are distributed across density tiers that respond directly to how close each zone sits to the wetland. Plots farther from the humedal carry the bulk of the count , think low-rise apartment buildings and clustered housing that make good use of the land without overwhelming it. As you move inward, the density pulls back naturally, with detached homes and larger chacras taking over near the wetland edge, where the environmental sensitivity of the terrain really calls for a lighter touch.

Medium-Density Zone Allocation

Based on technical reports filed by the project company in 2025, 1,150 of the planned 3,000 housing units fall under the medium-density category , making it the largest single residential segment at roughly 38.3% of the total program. In Uruguay’s current market, that kind of weighting tells you a lot about where developers see demand heading.

The zone is framed as “open and accessible,” with a clear middle-income focus, and it’s designed to anchor design diversity across the site. This isn’t filler. In a country where mixed-use, human-scale neighborhoods like those in Pocitos or Carrasco have consistently held value, positioning a segment this size around variety rather than uniformity is a deliberate structural decision worth paying attention to.

A few things stand out:

The medium-density zone sits above the lowest-density sectors, set back from the sensitive wetland edge , an important consideration given Uruguay’s environmental regulations around coastal and riparian areas
It supports varied housing typologies rather than uniform tower blocks, which aligns well with buyer preferences we see across Montevideo and the interior
No granular breakdown exists yet within this 1,150-unit segment, so the actual product mix still needs to be defined

That last point matters more than it might seem. Until developers specify what those 1,150 units actually look like , apartments, duplexes, townhouses , the numbers give you direction but not the full picture. Keep that in mind before drawing firm conclusions.

Medium-Low Density Breakdown

At 1,370 units, medium-low density carries the real weight here , 45.7% of the total 3,000 units, which makes it the single largest housing category in the entire breakdown. That’s not a coincidence. In the Uruguayan market, this range consistently hits the broadest buyer segment, from young professionals in Montevideo looking for their first property to families relocating from the interior who want space without the maintenance demands of a full low-density lot.

What the 2025 technical reports confirm is that this distribution was deliberate market segmentation, not a default setting. Sandwiched between the denser core and the low-density edge near the wetland buffer, this layer becomes the project’s residential backbone , the part that actually makes the numbers work financially and urbanistically.

Uruguay’s planning culture tends to reward density gradients that feel graduated rather than abrupt, and this design respects that. The built intensity here is calibrated to sit comfortably within the broader residential gradient, which matters when you’re talking about long-term absorption rates and resale value. Developers who have worked in similar mixed-use contexts along the Rambla or in Carrasco’s transitional zones know that getting this middle tier right is what separates a project that sells steadily from one that stalls. This one is built around that principle.

Low-Density Wetland Edge Units

The quietest part of this development sits right where it matters most , along the humedal edge, where 520 low-density units occupy the largest individual plots in the entire project. That’s a deliberate choice, and one worth paying attention to. In Uruguay, wetland-adjacent land carries real responsibility, both legally and in terms of long-term value, and the way this zone is laid out reflects that seriously.

Density drops off here for good reason. You get detached houses and grouped homes instead of towers, chacra-style layouts that spread horizontally rather than stack vertically, and green buffers designed to ease the transition between built space and protected wetland. These aren’t decorative gestures , they’re structural decisions that determine how livable this edge actually is.

What you’re looking at is essentially a perimeter zone, not the project’s primary housing mass. Its job is to hold the line between urban development and ecological boundary, and the low-density format is the right tool for that. Whether MVOTMA and the relevant municipal authorities will ultimately sign off on every aspect of this configuration is still an open question, and any serious buyer in this segment should factor that into their timeline.

That said, plots with genuine wetland proximity in greater Montevideo and along the Río de la Plata corridor don’t surface often, and when they do at this scale, the window tends to be short.

What Else Is Planned Besides Homes in Bañados De Carrasco?

The Bañados de Carrasco master plan covers somewhere between 226 and 228 hectares, so what’s taking shape here goes well beyond the roughly 3,000 apartments. You’ve got commercial premises, office space, and a range of housing typologies that move past the usual residential block format. It’s designed as an open, accessible neighborhood, not a closed-off enclave, which matters a great deal in a market like Uruguay’s where civic integration tends to hold long-term value.

Community facilities are genuinely built into the plan: a school, civic center, cultural center, and an observatory. That kind of local infrastructure keeps residents anchored to the neighborhood rather than driving out for every errand or activity. Sports spaces, recreational areas, and shared open zones fill in the everyday picture nicely.

What really sets this development apart for buyers thinking about liveability and appreciation is the environmental component. A metropolitan eco-park, lagoons, and green corridors run along the wetland edge, paired with a linear park and promenade that includes dedicated viewpoints. Uruguay’s coastal and wetland environments are genuinely irreplaceable assets, and having them woven into the urban fabric rather than pushed to the periphery is a real distinction here. A vehicle bridge connects the whole development to the existing road network, with low- and medium-density sectors also factored into the layout.

Why Is the Bañados De Carrasco Wetland Project so Controversial?

The Bañados de Carrasco wetland sits at the intersection of ecology, equity, and urban planning , and if you’re following the Uruguayan real estate market, this is a situation worth understanding carefully. A private development proposal seeking to reclassify this rural land for urban use has raised serious flags across multiple fronts, and the concerns are well-founded.

From an ecological standpoint, this wetland actively filters water and absorbs flood pressure for surrounding neighborhoods. Montevideo’s geography makes natural drainage systems like this one genuinely irreplaceable , losing that capacity doesn’t just affect the immediate area, it shifts flood risk onto communities that already deal with infrastructure gaps.

That brings up something harder to ignore: the social dimension. Nearby working-class neighborhoods lack basic services, yet a high-end residential project appears to be moving forward outside the usual regulatory framework. Leaving this land off protection lists while pursuing reclassification raises real questions about who planning decisions are actually serving.

Public engagement has been limited throughout this process, which only deepens the distrust. In a country where land-use decisions carry long-term consequences for entire districts, that kind of opacity tends to leave lasting damage , both to ecosystems and to community confidence in the institutions managing them.

For anyone evaluating property in or around this area, these unresolved tensions represent genuine market uncertainty. Understanding the full picture here isn’t just good due diligence , it’s essential.

What Approvals Does Bañados De Carrasco Still Need?

Bañados de Carrasco still has a long road ahead before any development can realistically move forward. The Junta Departamental needs to declare departmental interest first , that conversation is still very much ongoing as of July 2026 , and nothing else can progress until that step is resolved. Once that declaration is in place, officials can then vote on recategorizing the land from rural to urban use, which is its own separate process.

From there, developers would need to put together a Programa de Actuación Integrada Complementario, including fresh technical studies to support it. Given the wetland sensitivities already associated with this site, environmental authorization from the Ministry of Environment is also required, and that review tends to be thorough. Community participation and stakeholder outreach are mandatory steps as well, not optional formalities.

Each of these stages unlocks the next, so the sequence matters as much as the approvals themselves. None of them exist yet. Keeping that in mind is important when evaluating the 3,000-unit vision that’s already making the rounds publicly , ambitious numbers are easy to float before the regulatory groundwork is anywhere close to being laid.
