"Mary Fisher" randomly hit the keyboard and
produced:

I wonder if building regs inspectors thoroughly consider the foundation
aspect when allowing vertical extensions.

Surely, if the foundation aspect had thoroughly been investigated there
would have been objections?

The additional loading on most foundations from a loft conversion is
usually minimal compared to what's there already. Unless there is an
arrangement of beams and columns which concentrates a load at a
particular point, the foundations aren't usually checked by the BCO.

Building Control don't "allow" work to be carried out; their role is
to determine whether the work being carried out complies with the
technical requirements of the Building Regulations. I often put it
as, "Planning determine the who, what and where; Building Control
determine the how".

If the existing property is showing signs of movement, that's a matter
that should be addressed _before_ any loft conversion is considered.
One would presume that if the conversion was being paid for by a
secured loan, even a valuation survey would pick it up.
