Maison De L'eau | Cascais, Quinta Da Marinha

Acqua House – 7-Bedroom Residence, Quinta da Marinha | Cascais, Portugal

Some residences are built. Others are dreamed into existence.

Acqua House was conceived as a true work of art.
Set within the exclusive Quinta da Marinha, Cascais’ most prestigious residential address, this exceptional property embodies a rare vision of contemporary luxury, where architecture, water and nature exist in perfect harmony.

Reflecting pools gently surround the residence, home to elegant koi carp, creating the extraordinary illusion that the house is floating above the landscape. Throughout the day, the changing light casts ever-evolving reflections across the water; at sunset, the property takes on an almost ethereal quality, as architecture and nature merge into a setting of remarkable beauty.

Designed to dissolve the boundaries between indoor and outdoor living, expansive floor-to-ceiling glass walls frame uninterrupted views over the meticulously landscaped gardens and the surrounding golf course. Natural light becomes an architectural element in its own right, filling every space and creating an atmosphere of absolute serenity.

The social areas have been designed for sophisticated entertaining while retaining the intimacy and warmth of a true family home. Generous living spaces, elegant dining areas and carefully curated interiors reveal an exceptional attention to detail, with every material, texture and finish selected with an uncompromising commitment to excellence.

The private quarters comprise five magnificent suites, each designed as a peaceful retreat, with views over the gardens and reflecting pools. The principal suite stands apart as a truly exclusive sanctuary, featuring extensive dressing areas, a bathroom inspired by the world’s finest spas and private terraces created for moments of quiet contemplation.

Beneath the main residence lies an entire world dedicated to wellbeing.

An impressive heated indoor swimming pool forms the centrepiece of an exclusive wellness area, complemented by a fully equipped gym, spa facilities and spaces designed for complete relaxation. A private cinema completes the experience, offering all the comforts and amenities of a world-class resort without ever leaving home.

Outdoors, mature gardens, elegant terraces and peaceful courtyards create a variety of settings for open-air living, following the changing rhythm of the light throughout the day — from the first rays of morning to long evenings spent entertaining family and friends beneath the Atlantic sky.

Perhaps the greatest privilege of all, however, is the location.

Quinta da Marinha is internationally recognised as one of Portugal’s most exclusive residential destinations, where championship golf courses, an equestrian centre, five-star hotels, outstanding restaurants, the Atlantic coastline and the protected beauty of the Sintra-Cascais Natural Park coexist in perfect harmony.

Cascais Marina, the iconic Guincho Beach and the charming historic centre of Cascais are only minutes away, while Lisbon International Airport is approximately thirty minutes from the property.

Aqcua House is far more than an extraordinary residence.

It is a private resort.
A masterpiece of contemporary architecture.
An expression of understated elegance and timeless sophistication.

A property created not simply to be admired, but to be fully lived.

For those seeking one of the most exceptional properties on Portugal’s Atlantic coast, opportunities of this calibre and exclusivity are exceedingly rare.
