Dear home builders,
We would like to build a small single-family house and, if possible, avoid earthworks and a poured slab. The house is designed so that it can be dismantled and relocated if necessary. Is there a way to found on the ground without carrying out earthworks, for example instead of replacing a soil layer with frost protection material, simply compacting foam glass gravel to a level surface, placing concrete slabs under the exterior walls, or something like that? In my research, I have not yet found solutions without a poured concrete slab.

The soil condition is quite sandy with groundwater starting at 3m depth.
Built-up area 5x10m2.
No basement, the ground floor floor is drawn with 50cm high constructed beams (KVH, nail plates, glass wool WLG035) in a grid spacing of 62.5cm.

Greetings from Berlin

A house also needs various connections. Apart from the fact that I am not aware of any experimental communities that designate building areas for mobile modular house concepts: what (besides your tinkering fun) would you see as the main advantage of such a house concept?

- Circular economy. It would be nice if this does not turn into mixed construction waste at EOL and parts can simply be separated and reused wholly or partially.
- We would love not to seal the land. Saves costs on construction and dismantling/demolition, and the impact on nature is less.
- The non-renewable primary energy (PEI n.e.) required is enormous with a strip foundation and frost protection; building in a climate-friendly way is important to us.
- Maybe someday the floor area ratio will be adjusted and densification enabled. Then the house could be moved on the property or rebuilt elsewhere. Dismantled, it fits on a truck.

I suspect the ground is already sufficiently stiff with the 45cm high beams that two 10m long strip foundations would suffice. I will recalculate this tomorrow.

Greetings from Berlin!

There are a thousand ways and means... In the USA, construction is done by simply driving a number of fence posts (micropiles) into the ground.

In Russia, foundations are found on truck/car tires.

Great tip, thank you! I will look into the idea with the tires. Has anyone in [D] ever gotten that approved in a building application?

Basically, they are just pad or strip foundations, only without concrete.
