Quinta do Paço

The Health Valley

The one-of-a-kind health valley will offer premium houses and apartments to buy or rent, while featuring extended medical facilities to cater for the residents' wellbeing. With the 127ha area's fantastic selection of activities, Quinta do Paço will be an excellent choice for anyone seeking an active lifestyle, while still being able to rely on the immediate proximity of high-end medical services and staff.


As in all RIDDLE resort projects, nutrition will be a central part of the services on site, with expert chefs and individual nutrition plans supporting our guests' and residents' health and longevity. Sports opportunities such as horseback riding and tennis, as well as barrier-free buildings and a high level of electric mobility will make Quinta do Paço an incredible place to live and get healthy. 70% solar-powered and self-sufficient on a large amount of the fruit and vegetable selection served, this is the health valley of the future.


The Luxury Resort

With 470,000m² of rare land plot in Algarve and more than 1,5km of seafront overlooking an important natural reserve this rare seafront development with a luxury community is environmentally friendly and sustainable. A unique historical Demeure, an original 19th century french castle in typical Louis XVI style, is being reconstructed using the finest Sireuil Limestone quarried in France. A design inspired by the Palacio de Queluz, home of the Portuguese royal familly in the 19th century, itself inspired by the Petit Trianon in Versailles, this architectural masterpiece is headlining the domain.
