time to tackle the front - that is to say, master - bedroom (the one where you can have a bed
and stand up in the same room) on the 2nd floor. i really wanted to be able to just patch the holes in the original plaster/lath walls and stick a new drywall ceiling in and be done with, but it just wasn't viable.

ceiling furred out with new studs, as is de rigeur. this bedroom, like most of the 2nd floor, had no ceiling light, so had to add in that and a switch.

the wall had three loose outlets, one of which had dead wiring lead to it. so, those were replaced with new outlet boxes attached to the studs. the large patched hole above the window had been created in 1984 (thank you eric merrill) when they installed the drop ceilings/loose new wiring. and then they blew in cellulose insulation between the studs from the outside... and kept on blowing and blowing... such that the dropped ceiling had 40 gallons of insulation piled on top of it when it came time to remove it.

so, in the end, there were too many large holes and countless other cracks to merit trying to save the plaster/lath as the finished wall. here, we've started installing the 3/drywall over the top, as per the other rooms on the 2nd floor. the plus side is that it will
add some slight r-value to the insulation and better seal drafts from the outside.
