Citadel Within the City

Set within the Matosinhos Sul Urbanization Plan by Álvaro Siza, the former Brandão & Companhia canning factory occupies a privileged position near the coastline, retaining a strong connection to the industrial past and maritime identity of the area. The intervention reinterprets this legacy through a mixed-use development that consolidates healthcare, commercial, office, and residential functions within a unified architectural system, restoring the original envelope and chimney while introducing a contemporary layer.

 

Urban Integration

The proposal addresses the fragmentation of the existing structure by re-establishing continuity within the urban fabric. While the original volumetry occupied almost the entire plot, the project introduces permeable and green voids that allow natural light and circulation to penetrate the block. These interstitial spaces generate visual and physical connections between programs, enhancing accessibility to upper levels and fostering interaction within a dense, multifunctional urban environment. The ground floor accommodates commercial and service functions, offices are positioned on the first level, and residential units are organized in elevated volumes.

 

 

Programmatic Organization

At the entrance to the residential areas, a reception space opens onto a patio that operates as the central node of circulation, linking communal zones and distributing movement across the complex. The spatial hierarchy is structured to balance privacy and collectivity, ensuring fluid transitions between different uses. The distribution of the building mass into distinct volumes creates a dynamic composition that responds both to the scale of the plot and to the surrounding urban context.

 

 

Material Palette

The architectural language is articulated through a juxtaposition of materials with varying densities, notably pigmented concrete and aluminum stretched mesh. This contrast reflects the dialogue between past and present, emphasizing both the solidity of the existing structure and the lightness of the newly inserted volumes. Suspended above the courtyard, these elements introduce a sense of elevation and permeability, with a material palette inspired by the proximity to the sea. The intervention ultimately establishes a balanced relationship with adjacent buildings and the public realm, contributing to the revitalization of the block and supporting a broader strategy of sustainable urban development.
