The weekend before loading the truck, I drew for the very last time of the year our wall. This is the non-permeable one, with all the slats and all the spaces between them. I also drew two details in axonometry in order to understand how we would pre-fabricate the slat panels. We simply built two horizontals holding all the slats so that we would just put those horizontals on the exitsting frames.

 ( Elevation Scale 1:20 ) 

When we learned that our walls were going down by 1.65 meter, we were all pre-fabricating our walls and so we didn't have a correct drawing. This last drawing was then showing the size of the wall we would actually build. 

But when we arrived in Evian, we learned that an error in the measures of the slope would again change the height of the walls, by another 40 centimeters. Our walls were 2 meters smaller than the beginning. 

My drawing wasn't showing anymore the actual wall at the site. It became the part of the process and not the end of the process.

While we were doing the prefabrication of our frames, we needed to send the final Rhino file to the engineer in order to have his agreement to build our project. We did a skype with him to see the load descent in the proto.

At first, when he used our system of bracing and kept our wall at height meters high, we had 1800 kilograms at the left foot of the protostructure.

The engineer, Stephan and Teresa helped us to change something, like the bracing or the walls, in order to reduce the weight that went down to the foot. 

At the end of the Skype, we made a strong decision but we all agreed that it would be even better than before. The solution was to low down our walls. Given that we had already made every frames, we chose to take away one series of frames for every walls, which means that every walls was 1.66 meters lower. This choice allows us to have not so much bracings, and allows us to keep the energy of the project, which is the space that are created inside those vertical walls. What's even nicer is that the horizon with the Marechal's screen showed up again, and the link with their project is stronger than before.

Here is the scheme of the load descent that the engineer sent us when our walls were shorter.

We still have 650 kilos that goes down to the left foot of the proto, but we are going to dig 50x50x50 holes to put the proto inside and then put concrete.

The last week before going in Evian, which is the fifth week for the House phase, we all worked on doing the prefabrication. We started by going couple times at the cutting site, we used the measures of our drawings and of our Rhino files.

We then made some templates to assemble our frames with a right angle and with the correct distance. 

We then all screwed our frames. All our frames are built in a way that every horizontals sits on the horizontals of the proto, and that it won't be too heavy to lift it up.
