The PNN46 Apartment is a renovation project of a 65m² apartment located in the Anjos area of Lisbon. It is a very special project for the studio since the goal of the project was to transform the apartment into the home of the founding architect, Duarte Caldas.

Originally, the semi-basement space had very small rooms, where none of the bedrooms were large enough to even accommodate a double bed. Through careful interventions, the aim was to optimize the space and create a more fluid layout.

The first step was to demolish two walls to enlarge the rooms. This change not only allowed for an increase in the size of the spaces but also enabled the installation of the dining room in the center of the home, which was a key requirement of the project. The choice of stone for the dining table—grey with almost fluorescent green streaks—served as the starting point for defining the color palette of the remaining spaces.

The light gray tone of the walls was harmonized with the microcement floor and the kitchen cabinets. It was decided to leave the plaster exposed instead of covering everything with stucco, creating a textured effect that contrasts with the other smooth surfaces, particularly the polished stainless steel countertop. In the kitchen, the gray intentionally darkens in a niche on one of the walls, where the taller elements, such as the refrigerator, are positioned. On the opposite wall of the kitchen, a low countertop and a suspended shelf were placed to make the space feel lighter and more refined.

The living room, located in a former interior bedroom, features an orange floating shelf that serves as a TV stand, desk, and entryway console.

The old enclosed sunroom with frosted glass was replaced with large white sliding windows, three meters wide, that open onto a small patio with a concrete bench. The bathroom is hidden behind panels that simulate a built-in wardrobe, and inside, it is entirely clad in dark grey microcement.

In the bedroom, the use of large metallic lamps designed by the studio stands out. The bedroom door was extended to the ceiling, removing the glass transom. Adding a mirror to this feature provided a straightforward and cost-effective solution to enhance the sense of space and reflect natural light. Near the bedroom windows, wooden elements were created to function simultaneously as a step, side table, and bench. The shutters, whose height deliberately exceeds the window dimensions, were designed to dignify and maximize the perception of space, which originally felt more confined due to its location below street level.
