The original house consisted of just a ground floor with a surface area of 50 m². The upward extension consisted of an extra floor and a converted attic, bringing the total surface area up to 90 m², or resulting in 80% extra space.
- The additional load was reasonable. 320 kg/m3, or 96 kg/ml for a thickness of 30 cm for insulating walls and 48 kg/ml for a thickness of 15 cm for insulating gable walls.
- The walls and roof were lightweight and insulated, yet they still felt as sturdy as most of traditional buildings in the area.

- That is all it takes to heat the house for a year. And no air conditioning is required for the hotter season either, despite the location.
Mechanical projection meant that
- The four walls were finished in five days
- The roof was finished in only two days
In-situ projection ensured elements were perfectly self-insulated and that there were no thermal bridges where vertical walls joined together and where they joined with floors and the roof.
