A new address with history
"Designing a new old town is, above all, a challenge of human scale and comfort.”
Miguel Saraiva
Concept
His new home with a soul is located next to the 16th century convent where the Poor Clares once lived.
500 years later, with the true spirit of an ancient city and a modern design, your family will find a new home with history to live in.
Over the rivers and in communion with the garden, this will be your refuge, close to the city center.

Architecture
Your new home with history is a modern project with the S+A signature.
Clarissas brings modern design to everyday life.
Whether it's the comfort of each of the more than 700 apartments or the functionality designed for the development as a whole, the architecture of the S+A studio guarantees superior quality.
With Lisbon as its creative base and home to more than a hundred of its employees, S+A stands out for its ability to open up to the wider world, adaptability to new markets and resilience to the challenges facing a society in constant change. With offices in 9 countries, S+A is now a major player in several countries.
Investing in an area that is constantly being developed and enhanced.
Portugal is one of the 10 countries with the best quality of life and the Lisbon Metropolitan Area is one of the most desirable areas - which is why prices have been rising exponentially.
With the city center becoming inaccessible, the city expands and creates new centralities with quality construction at more affordable prices, in areas where the value of the m2 has been rising - in the case of Loures, from January to December 2024, the m2 rose by 12.5%*.
Buying an apartment in Clarissas - to live in, rent out or resell - is betting on a new (old) city that will grow in value, guaranteeing a return on investment.
International experience creates solid projects in Portugal.
More than 50 years of history.
Operating in 5 countries: Belgium, Luxembourg, France, Portugal, and Switzerland.
More than 3,200 employees, more than 780 houses and 750 apartments delivered each year, and annual revenue that exceeded 950 million euros this year.
Operating in Portugal since 2018, the company has invested approximately 450 million euros in more than 1,000 housing units and over 135,000 m²2 construction.
More than 300 million euros invested in the Poor Clares.
