Yeah I was trying to be clever, it was a wooden framed nightmare, victorian hospital conversion with shallow roof and stud built interior walls built approx 1' out from the real walls (which themselves were a foot think and no cavity)

 

No access to the stud cavity from above either due to layers and layers of opposing joists with new and old roof flooring! (I think it consists of original + 1950's + 2007 stuff)

 

The roof would have once been used for storage (probably up to a certain time point) but even after that was boarded out to allow inspection of pipes etc...

 

When the block was divided into townhouses, my parents got the original (stone built) staircase, but the later wooden 1950's era prefab stairs up to the loft was removed (we saw the pics - you can still see the opening into the loft (blocked with new plasterboard) and top of the handrail from the loft itself though! Sadly there are few other pics as the unit was very well guarded from closure in 1995 to building work not really that much later, starting from in 2005 with demolition of the 1950's/60s **** surrounding the listed victorian stuff, so it avoided the whole 'urbex' scene. Also my parents bit was the admin block anyway.

 

Otherwise I'm pretty proud of my fishing history

Yup same here with a massive drill bit.

 

Finding cavities bridged at the top a lot now though, (houses approx 2000 onwards?) with thick cement laid onto a plastic former.

 

That said if you're expecting it, one of the benefits of a long drill, just keep on going...

 

Cavities were always supposed to be closed, capped off, but most builders didnt. Cavities now are generally not closed to remove the thermal bridge, but the insulation in the cavity carries on up through the loft in one continuous sheet for want of a better word. Should be no gaps.

As Rich says, all common sense.

until you poke through the tiles.....

lol!
