About this home
A Haven of Design and Nature on the Paraná Miní Nestled in the heart of the San Fernando Delta, surrounded by canals, native vegetation, and wildlife, lies this exceptional 60-hectare property, conceived as a contemporary retreat in the heart of nature. Situated on the Paraná Miní River, with approximately 310 meters of north-facing riverfront, it combines architecture, technology, comfort, and sustainability in a setting of absolute privacy, with no neighbors in sight. Access is exclusively by water, from San Fernando, in approximately one hour by boat. The property consists of five lots and features a designer main residence, a second detached home for guests or staff, spacious docks, landscaped areas, and a vast expanse of virtually untouched natural landscape. Award-Winning Architecture The main residence was designed by MAPA Arquitectos (Argentina–Uruguay) according to principles of passive architecture and sustainability. The home received the 2022 Social Habitat and Sustainability Award and, according to the information provided, is Passivhaus certified. Its elevated design responds naturally to the conditions of the Delta and allows the structure to adapt to the river’s fluctuations, while optimizing orientation, cross-ventilation, sunlight exposure, and thermal efficiency. The house faces primarily north, taking advantage of natural light during the winter and reducing direct sunlight during the warmer months. Main House The residence spans approximately 240 m² of covered area, complemented by spacious outdoor galleries and decks. The floor plan features an open and bright layout, with a strong visual connection to the landscape. It includes: - Spacious entryway - Integrated living room, dining room, and kitchen - Library / lounge area - Master bedroom with en suite bathroom and walk-in closet - Two additional bedrooms - Den, usable as an office, library, or additional bedroom - Two additional full bathrooms - Guest restroom - Laundry room - Spacious utility room The galleries extend toward different areas of the property, creating outdoor spaces for dining, relaxation, and enjoying views of the river. A spacious covered deck serves as a true outdoor social space and features a grill, a large wood- or charcoal-fired oven, a gas burner for a paella pan or griddle, and a hanging fireplace. Materials and Finishes The construction combines high-efficiency technology with natural, warm materials. Notable features include: - SIP panel construction system - Elevated structure - Dry construction - Solid wood and laminated beams sourced from reforestation efforts - Incense wood floors - Interior paneling in guatambú and kiri - Solid kiri wood doors - Wood interior finishes - Schüco PVC windows and doors - Triple-pane hermetic glazing - Thermal break - Schüco hardware - Exterior cladding in pre-painted sheet metal The furniture and interior design were created using designer pieces by Solsken. Technology, Comfort, and Automation The house was designed to operate with a high level of autonomy and comfort. It features a comprehensive Savant/Lutron system for lighting and audio control, which can also be operated via mobile devices. The lighting was designed by Eli Sirlin, combining warm LEDs and RGB lighting both indoors and in various areas of the grounds. It also features: - Starlink satellite internet - Luxul Mesh WiFi - Indoor and outdoor sound system - Bose speakers - Sony receiver - 65" Samsung TV - Alarm system - Security cameras - CO detectors? Energy and Sustainability One of the property’s key distinguishing features is its energy infrastructure.

Dock and River Access The property features a private dock on the Paraná Miní River, designed to comfortably accommodate several boats and serve as the main access point year-round. It features a spacious sun deck area and has the capacity to moor approximately four large boats. The second home also has its own dock. In the Delta, the river serves as a means of access and connection. The architecture and landscape of this property were designed precisely with this in mind. 60 hectares of nature The land consists of five lots totaling approximately 60 hectares, with about 310 meters of shoreline along the Paraná Miní River. The surroundings combine landscaped areas with large expanses of native vegetation, canals, and natural scenery. The landscaping was designed and executed by Clara Billoch. It also features approximately 30 fruit-bearing trees, primarily citrus. Species native to the Delta’s ecosystem can be observed in the area, including marsh deer, overo lizards, and wild turkeys. The scale of the property allows for the consideration of various complementary projects, such as: - Nature lodge - Private retreat - Ecotourism project - Wellness-oriented development - Inland lagoon - Heliport, subject to the necessary authorizations - New constructions compatible with the environment and applicable regulations A property that is hard to replicate This is not simply a house in the Delta. It is a combination of 60 hectares of natural landscape, a residence with acclaimed architecture, high-tech infrastructure, energy self-sufficiency, direct access to the Paraná Miní River, and absolute privacy. A property designed equally as a permanent residence or private retreat, as well as for those seeking to develop a hospitality, nature, or wellness project of exceptional character.

Buying in Argentina as a foreigner
Yes, foreigners can buy property in Argentina.
The most important restrictions concern rural land, properties containing or bordering significant bodies of water and properties located within border security zones.
- Near coasts and borders
- Argentina does not have a coastal restricted zone equivalent to Mexico's. To preserve a common schema, this field groups areas subject to special rules: rural land, border security zones and certain properties involving significant permanent bodies of water.
- Residency
- Property ownership does not automatically grant residency. You must prove recurring income (Rentista Visa).
- Taxes and closing costs
- They depend on the state, the municipality and the property itself, so there is no single national figure. Ask the agent or our Concierge for an estimate on this home.
- Financing
- Financing for foreign buyers may be limited and depends on the lender, residency, documented income, financial history, currency, down payment and property type.
How buying works
Obtain tax identification
Obtain a CUIT or CDI as applicable and prepare passport, powers of attorney, translations and source-of-funds documentation.
Legal due diligence
Review title, ownership, seller restrictions, liens, debts, cadastral status, condominium rules and the seller's legal standing.
Check special restrictions
Determine whether the property is rural, located within a border security zone or contains or borders bodies of water subject to restrictions.
Reservation, contract and deed
Define price, currency, deposit, conditions and timelines; then execute the deed and register it.
This information is general and educational. Rules concerning purchases, taxes, rural land, security zones and registration may change or be interpreted differently by jurisdiction.
