Alarquitectos lines Lisbon apartment with colour-blocked walls and pine wood

Portuguese studio Alarquitectos has used walls of pink and blue to brighten São Sebastião 123, an apartment converted from a 20th-century office in Lisbon.

Tasked with revitalising the old workspace's dark and poorly ventilated interiors, Alarquitectos opened it up by removing the existing partitions and adding a courtyard.

Along with an existing outdoor space that has been reorganised, this courtyard doubles as a lightwell for the 167-metre-square apartment.
