Located in Lisbon's most prestigious and attractive boulevard, Liberdade Building 49 has particular importance in OTIIMA'S rehabilitation project portfolio.
The project has the signature of the renowned architect Ana Costa and distinguished real estate Prime Portugal. This collaboration gave birth to a timeless and sophisticated project, the intervention returned the building to residential use, thus resuming the initial vocation of this Avenue in the centre of Lisbon. This change in use from offices to housing implied changing the façade to adapt its image to the new use.
A completely re-skimmed façade, large bay windows and gold reflective panels lend the building an iconic and distinctive new look. The existing office building, designed by the Risco Architecture Office, used a system of metrics and proportions of the adjacent buildings (from the end of the 19th century) to which a new “layer” was added. This alteration project had as its principle the addition of a new thickness to the façade that would allow the creation of balcony openings and work on a system of reliefs and shadows that resumed the themes of the stonework.
Avenida da Liberdade, not only because of its scale but also because of its importance in the development of the city of Lisbon, was the scene of interventions of great architectural quality, which, despite being assumed to be something completely new, always established a dialogue with the city. The application of the
OTIIMA PLUS System thus was the perfect solution to allow the perfect balance between the privacy of living spaces and, on the other hand, the creation of outdoor spaces that are as generous as possible.
The existing cantilever at the level of the first floor of about 25 cm was taken advantage of to gain depth and to align with the façade of the adjacent building to the south. Thus, a new “skin” was added using new materials and constructive systems with different plastic characteristics and guaranteeing the necessary thermal and acoustic comfort.
