Hello!
I am in the idea stage of a project where I have been tasked with building a house "upside down." To achieve this, I want to build a completely square house, preferably in concrete with a paper roof and virtually no slope, and a "parapet" at the bottom that will simulate an upside-down roof.
I am wondering what kind of foundation and wall thickness, as well as insulation, is minimally required to support a concrete or wooden flat roof. Are there any good examples of concrete structures with built-in insulation?
Since I have my parapet, the interior floor needs to be a bit above ground level to have about 700-800 mm to the bottom edge of the window. This means I either need to raise my interior floor if I choose a slab on the ground, or build a crawl space. Do you know of any good examples with measurements for each?
Since the house is supposed to be upside down, I would prefer a roof that does not extend beyond the outer edge of the wall. The question is how to solve the air passage to the roof. I have thought that if it is not possible to lay a concrete slab, then to lay wooden joists with vent grilles on the outer wall for ventilation.
Any reflections?
