ADD FUEL is the work of Portuguese artist Diogo Machado.
A JANELA
‘A JANELA’ now lives in Osaka.
Commissioned by Visit Portugal and installed at the entrance of the Portugal Pavilion at Expo 2025 Osaka, this piece is a symbolic meeting between Portugal and Japan — made of tile, memory, and intention. It was an enormous privilege to create this work to represent our country at such a special moment. Official opening on June 10.
More than a sculptural tile piece, ‘A JANELA’ asserts itself as a symbolic place between times and territories — where tradition and invention intertwine. Each pattern is a trace, an inscription of transmitted knowledge, and at the same time, a gesture of renewal. It doesn’t merely evoke cultural images and symbols of both countries; it summons a sensitive archaeology of looking, where memory and material articulate a grammar of permanence. It does not show — it reveals. It does not illustrate — it challenges. By opening itself to the other and to the timeless, it returns us to the essential question of what we see when we look — and how the visible transforms us.
This piece took shape little by little — tile by tile, gesture by gesture. No work is born alone.

Between two horizons, a veil dissolves — Portugal and Japan entwined in a singular breath of form.
(Project commissioned by Turismo de Portugal).



Created in collaboration with the iconic Viúva Lamego, this project invokes the timeless ritual of hand-painted tiles—echoes of ancestral knowledge rendered in glaze and fire.

Within ADD FUEL’s studio, each tile finds its place — a quiet choreography of balance and harmony.
