ᐅ Cost per square meter of precast concrete slab

Hello everyone,
I am currently planning a flat-roof bungalow of about 150 sqm (1,615 sq ft).
I am not sure yet what kind of ceiling to choose. Could someone provide an approximate price per sqm (sq ft) for a precast concrete ceiling without insulation?

Regards,
Rainer
