Replacing the smelly carpet with laminate in Dave's room the guest room has escalated into installing insulation under the floor in half the flat. Which is definitely good in the long run by BY GOLLY do I want this disruption to be over.

Replacing the smelly carpet with laminate in my room will, I anticipate, escalate into creating a secret compartment under the floor with a trap door because I think I have 4-5 feet of space down there.. (plus installing under floor insulation in the other half of the flat).
