Ensamble studio: The Truffle

Why are we using soil as a shoring component and not a haystack?

spanish studio ensamble studio, run by architect antón garcía-abril, with collaborators ricardo sanz
and javier cuesta, have created ‘la trufa’ (the truffle), a small holiday house in costa de morte,
in the north of spain.
“The truffle is a piece of nature built with earth, full of air.
a space within a stone that sits on the ground and blends in with the territory.
it camouflages, by emulating the processes of mineral formation in its structure,
and integrates with the natural environment, complying with its laws.
We made a hole in the ground, piling up on its perimeter, the topsoil removed,
and we obtained a retaining dike without mechanical consistency. then, we materialized
the air building a volume with hay bales and flooded the space between the earth and the
built air to solidify it. the poured mass concrete wrapped the air and protected itself
with the ground. time passed and we removed the earth, discovering an amorphous mass”
