Process & backstage from Project Outeiro.

Every project holds smaller ones within.

A 240 kg fireplace, designed not as decoration but as a structural object.
Steel, balance and heat carefully considered, in dialogue between craft, art and architecture.

Designed by CAS Studio.
Built by metalsmith Artur Camponês.

Field Notes I – Great Zimbabwe

Nine hours on the road from Manica, where we were based.
Red msasa trees. Baobabs. Border dust and a golden sunset.

And then: stone.

Granite blocks shaped and laid without mortar.
Subtle inward batter. Curvilinear walls rising with structural clarity.

Not primitive, just intelligence in material. Built over 700 years ago.

Around it, wattle and daub huts.
Earth and timber. Flexibility and resilience.

Permanence in stone. Adaptability in earth.
A building culture shaped by time and territory.

Field Notes, Vernacular Architecture in Africa.

CAS Studio was forged in 2012, in Manica, Mozambique, through long field based investigation across Southern and Eastern Africa.

From the stone structures of Great Zimbabwe to earthen and reed buildings along the Swahili coast, passing through Manica and Gorongosa, we learned architecture by being on site.

Working with earth, material and craft shaped the way we design today.

Light Shaped by Nature

The ocean covers most of our planet.
It regulates climate. When it changes, everything changes.
It’s warming and becoming more acid.
Shells and corals are struggling.

Spending time in the ocean made it real.
The sea stopped being a postcard and became a teacher.

This lamp started there: a nautilus-inspired form.
Printed in biobased PLA, made locally, one at a time.
Each piece unique. No stock, no waste.

First piece of the series.

Architecture that reveals the place.

What drives and inspire us is simple:
Climate. Material. Craft. Context.

Álvaro Siza’s Leça Tide Pool (1966) and Boa Nova Tea House (1963) show this principle clearly.

There, the building does not try to stand above nature. It responds to it.

The rocks, the wind and the horizon were there first.

Architecture isn’t about imposing form.
It’s about working with what already exists and revealing the place through the building.

A building is more than a drawing.
It listens to place, to light, wind, and sun.
Built by hand, guided by precision.
An organism, not a machine.

Smart Homes with Living Materials.

Earth, cork, wood, stone: they are not inert, but alive.

They breathe, adapt, and balance the environment.

Technology should not dominate, but translate. In this way, sensors and electronic systems are mediators between human needs and material intelligence.

A house is not a machine but an organism: breathable, adaptive, regenerative.

Innovation begins with matter in dialogue with nature, not with circuits.
