Excellent.

Did they get special rot treatment or is the solum  guaranteed to be dry?

Osb webs or steel  frame?

 

Made in Elgin so localish too.

No special treatment.  Solum was built up with compacted infill after strip founds and under building done, then DPM then thin concrete screed poured.  Under floor space ventilated with air bricks so assumed to be a dry space.  Normal practice for a timber frame with suspended floors.
