The design of the book on the Gramaxo Foundation, the work of architect Álvaro Siza Vieira, seeks to synthesise certain values of space, light and materiality that can be interpreted not only in the architecture, but also in the record made by photographer António Júlio Duarte. Physically, the book is heavy, austere and clean.

We had the opportunity to learn about the process and the outcome of Claustro do Rachadouro through the lens of André Príncipe. We were inspired by the simplicity and restraint of the project that represents a unique definition of luxury.

These are architectural books. Their entire structure characterises them in this way. They have good, enlightening interviews — which I enjoyed reading — critical texts, sketches, drawings, technical drawings. About this, i don't want to — nor can i — say anything about this. I don't like ploughing into other people´s fields.

I have been following Nuno Miguel Borges' publishing project on and off. It focuses on current Portuguese architecture design.

I think that architecture books usually contain information, either graphic or written (in the form of text), which is generally very centered and focused on the architectural object itself, a building or a garden, sometimes benefited from someone's critical eye - I am talking about your typical monographs on architecture or landscape architecture.

The book "Termas Romanas de São Pedro do Sul" sums up the work done: it collects texts by archaeologist-historians, the architect and the landscape architect, sketches and photos that document the building's life and history. Its skillful printing and carefully curated materials make this book a timeless and rigorous publication. A book that is expected to survive the test of time, just like the project it documents.

This first phase of the work was a scouting of the territory: getting to know and understanding the structure of the building. After that, because it is a ruin, trying to perceive things that are not visible.

The book is designed with a fifth colour, a greyish green evoking water, the central element of João Mendes Ribeiro's architectural project for the rehabilitation of the Roman Baths of São Pedro do Sul.

In 2015, I started working on a photo essay for a book on to the rehabilitation of Mercado do Bolhão. My work consists of three stages, all very different from one another.

The Termas de São Pedro do Sul photos document the transformation of the building and its surroundings, from the ruin taken by vegetation until the end of the rehabilitation project.

After the book about the Lisbon Cruise Terminal, I started shooting the construction of the Gramaxo Foundation, in Maia, designed by architect Siza Vieira.

This work has several new things. It is the first time I photograph an architecture project. It's a building in a monastery I already knew, which has a very strong historical framework, and which will be adapted into a hotel by an architect I deeply respect, and he is my favourite architect.

In this work, the city and the river formed a kind of frontier. The constant point of reference was the relationship between the new construction and Alfama on one hand and the Tagus on the other. It was within this territory and over this area of the city, with its two very visually strong parallel landscapes, that I moved for three and a half years.
