Boulouki is a team of architects, engineers,

professionals of construction and heritage.

We have been researching on traditional building materials and techniques

to preserve them

and bring them into the contemporary construction sector

as part of our heritage,

and as part of a solution for a sustainable construction.

We really wanted to have a place at the mountains of Epirus,

because we are closer to where all this knowledge and craftsmanship began,

and it's still like an alive place that keeps a bit of this tradition.

We are at Frasta school, in central Tzoumerka in northwestern Greece.

We are at Frasta school, in central Tzoumerka in northwestern Greece.

This is the school that is being renovated

and restored by the team of Boulouki

to be transformed into a community hub

for traditional and sustainable building practices.

This is tacit knowledge,

something that used to pass from generation to generation,

how to build with local resources,

how to be resilient.

There is an interest for being more respectful for the environment.

So I think this is very positive.

But we cannot do something for the climate

without taking into consideration the building sector.

Using this natural material in a big scale

is a real challenge.

You have big companies

that are interested in selling products like cement,

because it's quick, it's easy, and it's safe for the direct results.

Traditional materials don't work like this.

They have their own time, their own character.

You have to follow them.

They affect our way of thinking and our way of living.

This combination of aggregates is working well

also with the color we like it.

I want a bucket of lime and two buckets of sand

and one bucket of marble sand.

The natural building materials have an image of

not very serious, but you have articles, you have books,

you have, like, proof all over the world.

You have cities made of earth

that are still here, that have more than 900 years.
