Spent the last half of the day starting the demolition of the gray house interior. Never done a project like this but I’m very interested to give it a try. The plan is to remove all of the wallboard (walls and ceiling) and see what shape the structure is in and how/if we can remove the various walls and open the inside. Ultimately we want to make it a guest house with all of the modern conveniences. Below is a before and a few afters. The structure so far appears to be in good shape. Lots of wasp and hornet nests in the walls, so good time to do it since they are dormant.
There is no insulation in the walls nor ceiling, the place had to be incredibly cold in the winter.
