52 Atlantic Estate

At the western frontier of Europe, where the cliffs of Sintra meet the Atlantic Ocean, 52 Atlantic Estate stands as a rare coastal sanctuary.
Spanning three hectares within the Sintra–Cascais Natural Park, the property quite literally ends at the sea — with a private path descending through the cliffs to the untouched Vigia Beach below.

Originally built between 1989 and 1993, the estate was fully remodelled and transformed between 2022 and 2025 by its current owner into one of Portugal’s most distinctive off-grid residences. Every intervention respected the Natural Park’s strict environmental and aesthetic guidelines, preserving the property’s Mediterranean and traditional architectural character while integrating modern comfort and technology.

The estate runs entirely on solar power with battery storage system and its own artesian well, ensuring complete energy and water independence year-round.

The main villa features nine bedrooms, spacious living areas, and stone façades that echo the region’s heritage.
Surrounding it are landscaped gardens, a swimming pool, outdoor dining pergola, helipad and several annexes, including a caretaker’s house and rural support buildings. Approximately 2.3 hectares are dedicated to agricultural and regenerative purposes, enhancing biodiversity and self-reliance.

Every technical upgrade — from solar energy to water management — was designed to increase efficiency while maintaining harmony with the surrounding cliffs, ocean, and sky. The result is an estate that embodies the essence of coastal living: silent, self-sufficient, and profoundly connected to nature.

Recognised internationally with the International Property Awards 2025 for Sustainable Residential Development and the Evergreen Awards 2025 for Best Oceanfront Property in Portugal, 52 Atlantic Estate represents a timeless vision of independence by the sea.

Where autonomy meets the Atlantic — a landmark on Europe’s edge.
