The Infinity House | Contemporary 6 Bedroom Villa In Quinta Da Marinha, Cascais

Located in Quinta da Marinha, one of Cascais’ most exclusive residential enclaves, this contemporary six-bedroom villa is set to become a landmark of Portuguese residential architecture. Designed by Marco Martinez Marinho, the architect behind The Wall House featured on Netflix’s The World’s Most Extraordinary Homes, this residence will be the world’s first luxury villa to incorporate 3D concrete printing technology in its construction.

Set on a 1,500 sqm plot with a gross built area of 1,193 sqm, the property offers 509 m² of above-ground living space, complemented by an additional 341 m² basement level, distributed across two floors plus a lower level.

The villa is conceived as two interlinked oval volumes inspired by the infinity symbol, balancing functionality and privacy. The “8” wing is dedicated to expansive social areas, while the “0” wing houses the private bedroom suites.

The layout comprises six bedroom suites, including a distinguished master suite with dual walk-in closets, a guest suite and a dedicated staff suite. Living spaces include two elegant reception rooms and two state-of-the-art kitchens, designed for both everyday living and refined entertaining.

Social areas are centred around a 90 sqm open-plan living room, which flows seamlessly into the fully equipped kitchen with central island and the dining area. Expansive floor-to-ceiling glazing ensures abundant natural light and a strong visual connection to the landscaped gardens.

Wellness facilities include a private gym and spa with sauna, changing rooms and laundry area. Outdoor spaces feature a private black-tiled swimming pool, multi-level terraces, and dedicated lounge and al fresco dining areas.

Sustainability is integral to the project, with photovoltaic panels for energy self-sufficiency, certified wood and recyclable steel, and advanced home automation systems for lighting, climate control and security. The use of 3D concrete printing significantly reduces material waste while optimising construction efficiency.

Quinta da Marinha is just minutes from Praia do Guincho, renowned golf courses such as Oitavos Dunes, luxury resorts including Sheraton Cascais and Onyria Quinta da Marinha, and the centre of Cascais. Lisbon and its international airport are within easy reach.

Currently under development, this project represents a rare opportunity to acquire a truly distinctive residence, where architectural innovation, advanced construction technology and a prime location converge in a standout asset within Portugal’s luxury real estate market.
