This beautiful restoration project in, Porto, Portugal was designed by Barbosa & Guimaräes Architects. When the area needed modernization due to a number of the buildings sinking, this one was saved, where others were demolished. The granite exterior was cleaned up and used as a shell for the modern fit out and extension that was installed.
The relationship between old and new must have been difficult to get right. Similar materials have been used to link the differing elements and I think the new additions are extremely honest. The housing element of the project sits across three floors, following the staircase up through the building and separated from a commercial unit and an office space.
I particularly like the mixture of uses in this project. It looks like it would be an incredible place to shop, live and work. I particularly like the sky lights, shown in the image above (via archdaily). As frameless as possible, the finishing has clearly been done to an extremely high level and the result is spectacular.
