Originally constructed in 1993, Atlantic Estate was acquired in 2020 by Donatien Roy with a vision to create a refined, self-sufficient retreat in harmony with its natural surroundings. Between 2020 and 2025, a series of thoughtful upgrades enhanced comfort, infrastructure, and sustainability. Focused on energy independence, water autonomy, eco-conscious architecture, and passive climate solutions, these improvements transformed the
property into a fully off-grid, resilient, and elegant residence.

Located in Portugal’s Lisbon District, within the Municipality of Sintra and the rural village of Assafora, 52 Atlantic Estate lies within the Sintra-Cascais Natural Park, a protected coastal area that preserves biodiversity, geological formations, and cultural landscape. Its elevated position atop the cliffs provides panoramic sea views and complete privacy, while remaining a short drive from Lisbon and international transport links.

Set within a 30,000m² private estate overlooking the Atlantic Ocean, the property integrates renewable energy, water autonomy, and eco-conscious architecture designed to minimise environmental impact and promote sustainable living. Perched on a coastal cliff, it enjoys a natural microclimate created by maritime air currents rising along the escarpment, ensuring stable temperatures and removing the need for air conditioning.

Presented by Oasis52, 52 Atlantic Estate stands as a model of sustainable luxury – a fully off-grid sanctuary where refined design, natural harmony, and ecological responsibility coexist.
