Working the essence of architecture: people

Founded in Porto, A43 unites art and science, creating spaces that emerge from listening: to the land, to light, and to the lives that will unfold within them.
Each project is born from this dialogue, where the human rhythm meets the natural order.

We believe that architecture has a soul. And that space shapes the way we feel, live, and connect with the world around us.

Because for us, architecture goes beyond function. It generates well-being, presence, and connection.

Our Work

Every project begins by listening to the place, to the human being, to what is said, and to what is felt. More than spaces, we craft atmospheres that awaken presence, evoke memory, and translate essence into form.

Adaptation

We consider the unique perspective of the client, according to specific demands, different budgets, functions that may look the same but that receive personalized treatment.

Our Team

We’ve come together from many different backgrounds, united by our passion for working critically—and with curiosity, integrity, and camaraderie.

Our shared goal: to design elegant, effective, and environmentally responsive solutions for an intentionally broad range of clients.
