FIVE TV's superbright logo - not the DOG's, it's ********

Approved Document L1B, 5.7 b. i. defines the replacement of an
existing layer as "stripping down the element to expose the basic
structural components (brick/blockwork, timber/metal frame, joists,
rafters, etc)..."

So I guess if you take up the floorboards, strictly speaking it's
notifiable. I wouldn't bother, and I bet nobody has.
