The well-established building, constructed in the mid-19th century as a nobleman's house and later transformed for various uses, such as a hotel for emperors or the headquarters of the Cinema Club of the Portuguese city of Porto, has received a new program from the Diana Barros Arquitectura studio, focused on converting it into collective housing.

Given the predominance of tourist use in the area, the studio proposes a mixed use for the building, focusing on housing on the upper floors and commerce and services on the ground floor, where priority is given to preserving the careful decoration of the carpentry framed in the compositional rigor of the 19th-century façade and the staircase in the core of the building, topped by a central skylight and extended to the upper floor.

The project by the portuguese studio Diana Barros Arquitectura respects the versatility of the historic building by maintaining the organization of the common areas and entrances, preparing it for a new century and a half of use through a design that emphasizes and differentiates the various uses through the textures and colors of the materials used.

With the fundamental objective of creating a robust and coherent complex, functionally integrated but adaptable and capable of making the most of the natural and human resources invested in its rehabilitation, prolonging its useful life, the project takes care, through a construction system that respects the original elements, of the scale between the original building and the new domestic uses introduced.

Project description by Diana Barros Arquitectura

Built in the mid-19th century to be the house of a Douro nobleman, the building's fame was consolidated over time by the meticulous decoration of the woodwork, framed within the compositional rigour of the 19th-century facade, and the incredible staircase in the core of the building, which extends to the top floor and is topped off by the central skylight.

It has embodied various uses over time, from a hotel prepared to receive emperors, to the headquarters of a resistance movement against the Estado Novo, from the home of the Oporto Film Club to a driving school. The proposed programme involved making it embody another: collective housing with commerce and services on the ground floor. Perhaps more pedestrian, but no less daring, given the dominance of tourist use in the area.

The project tried to respect the incredible polyvalence of a building that was once almost everything, keeping the organization of the common areas and accesses, the careful decorative work that survived in the stonework of the facade and in the interior and exterior carpentry and the constructive system used in the slabs and central staircase. The tension between the scale of the original building and the domestic uses now introduced is accentuated by the elemental design of the new elements, emphasising the textures and colours of the materials.

The fundamental aim was to create a robust and coherent whole, functionally integrated but adaptable and capable of making the natural and human resources invested in its rehabilitation profitable, prolonging its useful life and preparing it for another century and a half of use and as many other incarnations.
