While the warren-like layouts of many of the city’s historic apartments are merrily being stripped away in favour of more fashionable open-plan arrangements, this trio of apartments by Aurora Arquitectos makes an effort to preserve the original design.

When architects Sofia Couto and Sérgio Antunes were commissioned by a developer to transform one floor of the 18th-century building into three apartments they paid careful attention to retaining traces of what had been left behind.

Three decades of use as a tannery in the late 20th century depleted many of the original features, leaving only the floorplan and a few ornamental mouldings and paintings.

The floor has been carefully subdivided to create three new apartments, without the addition of corridors or extra circulation spaces commonly added in contemporary renovations in the city.

This attention retains the “integrity” of the Pombalino building, which was built to new seismic resistance standards following the 1755 Lisbon Earthquake under Prime Minister Marques de Pombal – from whom the typology gains its name.

In keeping with the style, the generously sized rooms are sparsely decorated in a monogenous style.

Doors, shutters, cabinetry and skirting boards are made from pastel-painted wood, which each apartment given its own individual colourway.

The clean lines and continuity of either pale blue or cream paintwork throughout offsets the few remaining original features.

Surfaces made from Liós limestone, pine wood and handmade tiles are a further nod to the traditional decoration of buildings of this era.
