Lisbon-based architecture studio AVA renovated the interior of this eye-catching apartment in Portugal’s capital city. Situated on the first floor of an 1893 building, the loft is occupied by a married couple (both engineers – dear lord!) with two small children. The designers chose to keep as much of the existing space as possible, preserving the apartment’s old timber floor and the existing layout of the rooms, with the added extension of two bathrooms. Harmoniously combining contemporary elements with the property’s history, including the elaborate stucco decorations on the ceilings, the designers have created an airy and calm living space that displays a sense of playfulness and humor.
