1. An open system for a closed cycle. 
Integrated design, manufacturing and process open platform.
Each shelter is completely biodegradable, and no toxic components are used throughout its life cycle –extraction, manufacturing and shipping- achieving a closed cycle like those in natural processes not marked by humans. 
Designed and manufactured according to the techniques available in each territory.
We use mainly CLT panels and three-layer boards. Our supply-chain net of local producers minimises time-cost-energy motion. Each family comes from a known forest, and we only make as much timber as it will be able to grow back in new trees, during the life of each family of shelters.
Each shelter is a carbon sink, absorbing more CO2 than it produces.
When possible, we use only dead trees, or try to bring derelict logs, boards or shelters into a new life.

2. No waste.
Material fabrication techniques. 
We make the most of each board.  Current material CNC fabrication techniques allow us to achieve a maximum material economisation, by integrating nesting as an initial design ingredient. Unused board areas become gifts and toys. CNC milling leftovers become protectors for transportation.
We are starting to collaborate with CLT panels manufacturers in order to bring the whole potential of timber into innovative panel solutions, including the use of geometry instead of chemical adhesives.

3. Positive ecological footprint and clean motion.
Carbon neutral transport and supply chain net. 
We seek real traceability of all their life cycle. Wood is transformed as near as possible from its mother forest. That’s why we collaborate with lumberyards, timber manufacturers and craftsmen from different parts of the world that meet our will in this regard. Only in this way can we guarantee that our goals are actually fulfilled.

4. Built to last more than four generations. 
Planned endurance and updating.
Little maintenance is required.
Spare parts are easy to make. No stocks are necessary.
The older it gets, the better it works. 

5. No packaging. 
Crafting process leftovers are thought so they become the packaging system.
Wrapped in a rope, that can be reused as a swing or as the surface to sit on.
Traveling.
Easy to transport.
You can carry most shelters like a rucksack.
All fit in a big trunk or a small van.

6. Reversible.
High performance, second life adaptable building envelopes. 
Fully assembled and dismantled without any screws or glue, by intuition or with little instructions.
The joint system adapts to the behavior and nature of each kind of timber, in order to ensure complete reversibility.
We use as few pieces as possible, all of them have more than one different use.
None is just an assembling piece.

 

-In a world where there is more chairs and roof space than people, what is the sense of making more shelters?

-When we were kids, we enjoyed making little huts in our family's hazel trees fields, or on our schoolyard, using salvaged materials we found around us. Later on, we developed this passion thanks to our training as architects (1). From 2009 to 2013, we worked on our PhD thesis about the maison that Jean Prouvé built for his family in Nancy in 1954. The story of that house is also the story of the end of the dream of high-quality, prefabricated houses affordable to everyone. The questions raised during this research, have implicitly guided us on our post-doctoral research journey with the CIY aixoplucs.

 

-How did this all start?

-Teresita, my grandmother, lived in a long, old flat. Every time we visited her place,
we sat under a 1870s-looking, 1940s-built roof,
on some 1890s-looking, 1950s-made chairs,
had coffee on a 1900s-looking, 1960s-made table,
on cups kept on a 1800s-looking, 1970s-made cupboard.
Her generation and our parent's,
built as much indoors as all previous human generations combined,
made and bought a big amount of furniture,
far more than they needed.
owever, the next generations of our family won't be able to inherit all these goods. It is not a matter of style or fashion, but for several practical reasons:

1. Their energy performance is lousy. They are too hot in summer, too cold in winter. They need too much disposable energy, they produce too much waste. They were built in cheap fossil fuel era. They are fossil fuel junkie environments.

2. They are too loose. All the joints, screwed, nailed or glued, have moved or lost their resistance.

3. They are too big and heavy. As they can't be taken apart in order to reassemble them, the cost of moving them to her offspring is unaffordable. Some don't even fit through the door.

4. They are too small. We have grown more than 10 cms. during the last century.

5. They are too dirty. All the upholstery and stuffing can't be taken out or easily washed. They contain stains, bacteria and dust mite from more than 60 years ago.


From this first CIY shelterware, we keep exploring how we can help you
with open source architecture.
We hope your great grandchildren can still use these shelters, so they are passed -and improved- from generation to generation.
