The ”Infinite House” is a unique architectural work designed by architect Marco Martinez, located in Quinta da Marinha Sul. This property, with a total construction area of 1,193 square meters, elegantly integrates the concepts of continuity and balance, symbolized by the numbers eight and zero. When viewed from above, the residence reveals a distinctive design: two interconnected oval structures forming an impressive infinity symbol, with facades made of 3D-printed concrete that blend innovation and art.

Upon entering the property, you are greeted by a tranquil and private environment, in perfect harmony with the surrounding natural landscape. The ground floor features a spacious living area of over 90 square meters, organized into three distinct but connected spaces. This floor also includes a dining room for 12 people and a kitchen with a central island, ideal for intimate dinners with your private chef. Adjacent to the main kitchen is a fully equipped support kitchen. On this level, there is also a guest suite that offers comfort and privacy.

Ascending the staircase or using the elevator, you will discover four bedrooms on the first floor, all with en-suite bathrooms. The master suite, with 85 square meters, stands out, featuring a spacious bathroom and two closets.

The lower floor is dedicated to wellness, with a gym, sauna, and a glass window offering serene views of the patio, which is connected to the pool by a waterfall. This level also includes a service room, multifunctional technical areas, and a garage with capacity for four cars.

A staircase next to the outdoor social area leads to a panoramic terrace with stunning views.

The house is located near the sea and Guincho Beach, within walking distance of the Oitavos Dunes golf course, the Sheraton Cascais Resort and Onyria Quinta da Marinha Hotel, and the CUF Cascais Hospital. With easy access to the A5 highway, it is just 30 minutes from Lisbon Airport. Renowned international schools, such as Deutsche Schule Estoril, Santo António International School, King’s College, Tasis, and St. Julian’s School, are just a few minutes’ drive away.

What truly distinguishes this property is its unique architecture, deep connection with nature, and commitment to sustainable materials and technologies. The water features surrounding the southwestern portion of the property create an unparalleled atmosphere.
