Located in one of the most exclusive areas of Lisbon, this elegant building in the heart of Príncipe Real features a rehabilitation and expansion project already approved. With a current gross area of 676 sqm, the project includes a 100 sqm expansion, distributed among balconies, terraces with river views, and a 60 sqm mezzanine on the top floor, part of a sophisticated signature duplex. The project is by renowned French architect Isabelle Stanislas, internationally recognized for her fusion of art, architecture, and contemporary design. The intervention respects the historical character of the building while enhancing it with a refined and modern aesthetic. On the ground floor, there is currently a yoga center in a fully renovated area, executed with great attention to detail. The approved extension of the garden façade’s arches down to ground level stands out, creating a striking architectural effect that integrates with the outdoor space. The 1st and 2nd floors are designed to accommodate 1-bedroom and 3-bedroom units, highlighting original features such as ornamental ceilings, balconies with river views, and an elevator that ensures comfort and accessibility. The interiors are defined by natural light, functionality, and respect for heritage. The top floor features an exclusive 200 sqm duplex, complemented by a 60 sqm mezzanine, a 20 sqm terrace, a solarium, and panoramic views over the Tagus River and the city. This is a unique investment in one of Lisbon’s most charismatic and sought-after neighborhoods, ideal for luxury residential development or a mixed concept of living and wellness, with a privileged location, Lisbon authenticity, and proximity to the historic center.
