ᐅ Strip Foundation versus Slab Foundation

Hello,

I am considering building a house using a timber frame construction method.

The plot is about 1 meter (3 feet) below street level, so it would need to be properly filled and compacted.

I discussed a scenario with a carpentry company to build strip footings instead of a slab foundation.

This would essentially create a crawl space. The ground floor would then have a beam ceiling.

The beam ceiling would be insulated similarly to an exterior wall. To protect against rising damp, a membrane and cement fiberboard would be installed at the bottom.

Are such constructions sustainably stable?

Is it advisable to avoid strip footings?

Best regards

This is generally feasible and can be significantly more cost-effective than building up the ground with a compaction certificate. I built my own house this way, using a ventilated wooden floor slab. The key factor is the soil survey, which should be the first step and includes important recommendations for the foundation.

Okay, and do you also have a membrane and cement fiber board underneath?

Or is there a different construction method?
